1. Initial Stage

The initial stage of mobile app development is divided into two categories;

  • Research & Analysis

According to one of the research departments of iOS app development, there are already more than 2,097,100 apps accumulated by the Apple App Store.

Initial Stage of Mobile App Development

According to the graph shown above, there is a tight competition of applications in the mobile app development market and you should avoid taking the risk by creating a similar iOS app, which is already available in the Apple App Store.  

In order to get more satisfactory results for your iOS app, you must conduct good market research to cross verify the similarity of the developed mobile app and to enhance the features of your app. 

It is also a good practice to identify the mobile apps of your competitors by analyzing the rating section of their iOS apps where you can get to know the experiences shared by the app users.

  • Compliance With Apps Stores Guidelines

While developing an iOS app, you must successfully meet the guidelines published by Apple for design, user privacy, security, and several other essential aspects needed for the iOS app development. Along with the right guidelines, an iOS app also must meet the requirements set by the Apple Store.

LocationApproximate TimelineEstimated Cost (Approx)
India1 – 3 Weeks$30 – $50 Per Hour
Europe1 – 3 Weeks$35 – $90 Per Hour
Canada2 – 4 Weeks$40 – $80 Per Hour
USA2 – 3 Weeks$45 – $90 Per Hour

2. App Designing

In this phase of iOS app development, Concept & Wireframing and UI/UX are the two parts that must come under consideration while developing an iOS app.

  • Concept & Wireframing 

When you are done with the concept of your iOS app, the next step is to start the documentation process for the requirement of the app’s design. 

The designing process includes developing wireframes, which are the digital sketch or blueprints of your iOS app that show how the iOS app will look after the finalization.

  • UI/UX Design

In order to make the app more compelling and impeccable, you should determine the user experience of the app to see how the app would look. 

Our main objective in this step is to create an appealing design that is easily navigable for app users. However, you also have to keep the guidelines published by Apple in your mind, while creating the UI and UX of the iOS app.

LocationApproximate TimelineEstimated Cost (Approx)
India100 – 150 Hours$30 – $45 Per Hour
Europe100 – 170 Hours$35 – $60 Per Hour
Canada120 – 200 Hours$60 – $100 Per Hour
USA120 – 180 Hours$60 – $110 Per Hour

3. iPhone App Development

Now, we will start the iPhone app development process in this step. This stage is divided into three parts; Software Architecture, Backend Development, and API Design, and Design Integration & Logic & API Integration.

  • Software Architecture

This part is considered one of the most important steps in the process of iOS app development. Here, you have to plan for the architecture of the app and account for the components of the Model View Controller (MVC). 

There are three components of MVC; the user, the data, and the software. The requirement of app architecture is necessary in order to ensure the stability and scalability of your iOS app. Also, you need to make sure that all the steps are going in a sequence.

  • Backend Development and API Design

Backend development plays a vital role in the mobile app development process. Backend development is responsible for handling the server-side development that includes:

  • The functioning and maintenance.
  • Authentication of the user account.
  • Push notification services.
  • Customizing the user experience.
  • Account management.

Now, let’s understand the role of API design in iPhone app development.

Application Programming Interface (API) plays a crucial role in mobile app development because APIs are responsible for connecting the frontend and backend of an iOS app. In simpler words, API serves as a bridge between the frontend and the backend developments.

  • Design Integration and API & Logic Integration

In the Design Integration stage, the iOS app developer needs to integrate the UI/UX and create a navigation flow with dummy data using the Xcode Storyboard.

Once you are done with the navigation process and UI/UX integration as per the requirement of the iOS app, you will enter into API & Logic integration stage. In this stage, the iOS app developer needs to work on API integration in order to show the live data rather than dummy data that the developer has used for navigation flow and UI/UX integration in the above step.

App DevelopersApproximate TimelineApproximate App Costs
Frontend Developers160 – 170 Hours$35 – $45 Per Hour
Backend Developers200 – 220 Hours$35 – $50 Per Hour

4. Testing & Launching

This is the last stage of iPhone app development where you will test and launch the application. Let’s understand both of these parts for more clarity and to know their costs.

  • Testing

Once you are done with all the technical aspects, you will enter into the Testing stage. This stage is very crucial as you have to consider Apple’s approval and all the challenges while submitting the iOS app.

You, as an iOS app developer, also need to review several essential factors like debugging, security, optimized performance, optimal memory, impeccable user experience, and checking the guidelines published by Apple for the compliance part in order to launch your iOS app.

LocationApproximate TimelineEstimated Cost (Approx)
India20 – 25 Hours$25 – $35 Per Hour
Europe30 – 40 Hours$30 – $55 Per Hour
Canada28 – 42 Hours$60 – $90 Per Hour
USA40 – 50 Hours$70 – $90 Per Hour
  • Launching

In the Launching stage, make sure that you review and test the iOS app properly in order to avoid rejection from the Apple App Store. 

Important! The submission of your iOS app on the Apple App Store can take up to two weeks depending on the quality of the submitted app and how well the guidelines are followed.

Now, we have discussed the iPhone app development cost phase-by-phase. However, there is one more iOS app development cost that you must know, which is the Project Management Cost that is required to manage your iOS app development.

Create Login Screen Using TextInputLayout In An iOS App

We are here to learn about creating a login screen. This is generally the first step in creating a mobile app. This allows, user to create an account on your app and later on can authenticate the user. As it is a basic step, this article is a fit for users who want to create their own iOS app or the developers who are new to iOS mobile app development.

Here, for creating an input field we are using a placeholder attribute that allows the user to view the text inside of the Textbox by providing the hint for each text field. Also, a placeholder disappears whenever the users try to input the text in the provided text field.

However, TextInputLayout, also known as ‘Floating labels’, is a layout that does not disappear, in fact, it wraps a placeholder by displaying the clues in the form of floating text while inputting the text.

Well! You do not get an in-built TextInputLayout functionality in iOS app development. Thus, this tutorial will help iOS mobile app developers like you to initialize floating labels for your iOS apps using the ‘Swift’ programming language.

The Signup screen of iOS mobile apps provides you with the text fields that allow you to enter the text such as: 

  • Password 
  • Age 
  • Email Address 
  • Phone Number
  • Name

There is also various other personal information as well, which is required for signing up on the app. The text field takes the input in the form of numeric, special characters, and plain text. In order to open the keyboard on an iOS app, you just need to tap on the placeholder.

Now, let us get into iOS app development and take a practical step-by-step route to create a signup screen for the iOS app using TextInputLayout, which will allow you to input the user name, email address, age, and country.

Steps To Create UI In iOS App Development

  • Open the Xcode in your Mac and create a new project.
Open the Xcode

  • Select “Single view app” in the iOS tab and hit the “Next” button.
Single View App in iOS Tab

  • Now, enter the desired product name in the “Product Name” field, and select the ‘Swift’ programming language. Click “Next” and save your project on the hard drive.
Enter Desired Product Name

  • Great! Now, under the “Product Name” tab, go to the “Main storyboard”, and click on “View Controller”.
Go To Main Storyboard

View Controller” provides you with the TextInputLayout on the selected iPhone simulator along with customizable “Text Fields”, “Label”, and an action performing “Button”.

  • In this step, drag and drop the required text fields and action “Button” onto your simulator from the object library.
Drag and Drop Required Text Fields

  • Now, customize your app as per the requirement by renaming the action “Button”, changing the background of the app, and many more.
Customize Your App

After applying the customized settings, the login screen of the app appears like this:

Applying Customized Settings

  • Important! Do not forget to add align constraints to your app in order to avoid overlapping the created text fields during the “Build” phase.

Great! Now, it’s time to write the placeholder text in the above-created text fields.

  • Click on one of the text fields. Now, a customizable placeholder text field appears in the top right corner of the “View Controller”. Enter the text and align it as per your need.

Repeat this step for the remaining text fields, and “Button”.

Now, you can also customize the on-screen keyboard for each text field. For example, if you want the users to enter their age in one of the text fields, you can select a numeric keyboard from the “Keyboard” options.

Customize On Screen Keyboard

Well done! You have successfully created the UI of the app using TextInputLayout.

Quickly! Let’s come to the coding part of this tutorial.

Steps To Set Up The Text Fields And Action Function In “ViewController.swift”

Follow the below-written steps in order to initialize all the “Text Fields” and a created “Button”:

  • First of all, open the “Assistant” header in order to view the screen in the multiview option. 

This will lead you to the “ViewController.swift” tab where we initialize “IBOutlet” for each of the text fields and “Login Button”.

ViewControllerSwift Tab

  • Now, press and hold the “Control” key and drag-and-drop each text field to the “ViewController.swift” tab from your “Main storyboard” under “class ViewController: UIViewController”.

After this process, assign a unique name to each of the text fields.

The code snippet for the text fields is as follows:

import UIKit

class ViewController: UIViewController

@IBOutlet weak var userNameField: UITextField!

@IBOutlet weak var emailAddressField: UITextField!

@IBOutlet weak var ageField: UITextField!

@IBOutlet weak var countryField: UITextField!


  • After initializing the text fields, it’s time to initialize the action function for the created Button, which is responsible for performing the assigned action such as submit, login, return, etc.

For that, drag and drop the Button, holding the “Control” key from your “Main storyboard” to “ViewController.swift” under the function “override func didReceiveMemoryWarning()” and enter the name of this function. For example, we are using enterTapped in this tutorial.

The code snippet for the action function is as follows:

override func didReceiveMemoryWarning()



// Dispose of any resources that can be recreated.


@IBAction func enterTapped(_ sender: Any)

Thankfully! We have initialized the Text Fields and Login Button. Now, it’s time to understand the remaining coding part in order to build and run your project on the simulator.

Steps To Implement TextInputLayout In iOS App Development

  • Go to “ViewController.swift” and assign a delegate to all of the Text Fields under the function “override func viewDidLoad()”. Follow the below-written code snippet for the same:
override func viewDidLoad()



userNameField.delegate = self
emailAddressField.delegate = self
ageField.delegate = self
countryField.delegate = self

  • Now, in this step, initialize another function “override func touchesBegan()”, which allows you to return to the login screen. This function is used to disappear the numeric keyboard, upon touching anywhere on the login screen, after inputting the “Age” in the “ageField”. The following code snippet for this function is as follows:
override func touchesBegan(_ touches: Set, with event: UIEvent?)



The wait is going to be over! Just one more step and we are done.

  • The final step involves creating an extension for the “UITextField” that allows you to return to the login screen after inputting the text in each Text Field. Just press the “Return” key and the Text Field will accept the entered text. Follow the code snippet written below for the same:
extension ViewController : UITextFieldDelegate


func textFieldShouldReturn(_ textField: UITextField) -> Bool {


return true


The complete implementation to create a login screen using TextInputLayout in iOS app development is as follows:

import UIKit

class ViewController: UIViewController


@IBOutlet weak var userNameField: UITextField!

@IBOutlet weak var emailAddressField: UITextField!

@IBOutlet weak var ageField: UITextField!
@IBOutlet weak var countryField: UITextField!

override func viewDidLoad()

userNameField.delegate = self

emailAddressField.delegate = self

ageField.delegate = self

countryField.delegate = self


override func didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.


@IBAction func enterTapped(_ sender: Any)



override func touchesBegan(_ touches: Set, with event: UIEvent?)




extension ViewController : UITextFieldDelegate

func textFieldShouldReturn(_ textField: UITextField) -> Bool

return true

Finally! We are done. 

If the on-screen keyboard does not appear on the login screen of your app, Go to the “Hardware” option on your Xcode, click on “Keyboard”, and select “Toggle Software Keyboard”. And the keyboard will appear on the login screen.

Toggle Software Keyboard

After building the project successfully, the login screen of your app will look like this:

Building Project Successfully

Login Screen of Your App

You may also use validations for the created text fields such as email validation, which prompts the user to enter the correct email address, password validation for entering the correct password, and many more as per the requirement of your app. For example, you can use the following code snippet in order to apply email validation in iOS app development.

func isValidEmail(email: String) -> Bool
let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

if let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
return emailPred.evaluateWithObject(email)
return false

We will cover the validation part in our next blog. Stay tuned!


In this swift iOS app development tutorial, we have concluded that in order to achieve great conversation goals, the iOS app developers should provide a better user experience in iOS app development. A placeholder is one of the features provided by an iPhone app development company that reduces the user’s risk of stumbling while filling forms because a placeholder puts persistent instructions and hints outside the empty text fields.

Send Push Notifications to React Native App

How to Send Push Notifications to React Native App Running on an iPhone

Push notifications play a vital role in providing you with timely updates and also allow you to re-engage effectively with customized content. It is a message displayed to you outside of the application’s normal UI whether or not you are using the app. You can create the push notifications with the help of the nodeJS server, which is responsible for sending the notification payload to the Apple Push Notification service (APN).

This article will help you step-by-step to configure a react native mobile application that can receive a push notification on an iPhone. In order to follow this guide, you will require an iPhone/iPad, a Mac, and an Apple developer account.

3.1 Enabling Push Notification Capabilities
3.2 How to Configure App to Retrieve the Token?
4. Set Off a New Notification from a NodeJS Provider Server
4.1 Initialize a Trusted Connection to APNs
4.2 Create and Send a New Push Notification Payload
5. Conclusion

Let’s begin. Now first understand:

What is a Push Notification?

As mobile app developers, we sent push notifications on the apps installed on the user’s mobile phones. In this article, we will focus on how to send a push notification on a simulator during an iPhone app development. There are mainly two types of notifications; foreground and background notifications.

  • A Foreground notification is a type of notification that you will send when the application is currently running. 
  • A Background notification is a type of notification that you will send whether or not the mobile application is currently running. 

Why most  mobile app development companies are asked to add push notification services:  

  • Push Notification is a great tool for a marketing company to engage a user with the mobile application.
  • Advertisements/ offers can be sent using push notifications to increase the transaction like the dominos app sends notifications for a special offer to increase sales at non-peak hours. 
  • Brand recall value can be increased with the help of push notifications.
  • They also assist in sending the transaction receipts at a fast rate.

What is Push Notification Architecture in React Native App Development?

Push Notification Architecture in React Native App Development

Sending Push notifications on react native applications, we need to use APN (Apple Push Notification services). This can be used after creating an Apple ID at the Apple developers forum.

APN is recommended as it can send notifications on iPhone mobile devices without knowing the IP address.

React Native app developers send push notifications in an iPhone app by registering a mobile app to get a push notification token. This token is a long string, which is responsible for uniquely identifying each mobile app device. 

In the next step, the token will be stored in a database on the server. Then, you handle the received notification after sending it. 

The next step is to store the token in a database server. Then, a notification will be sent to the mobile app. 

Now, let us go deeper and follow a step-by-step procedure for sending push notifications on iPhone mobile apps.

How to Register Your iOS App to APNs?

The first step includes the registration process of your already running app to the APNS in order to retrieve the token. This requires some configuration.

1. Enabling Push Notification Capabilities

1.1.  In the Apple Developer Account.

In the first step,

  • Go to the Apple developer account and find the App ID.
  • Enable the push notification capability for App ID.
Enabling Push Notification Capabilities in Apple Developer Account

  • Here enable the push notification capability for this Apple ID.

1.2.  In Xcode

  • Open Xcode on your Mac OS and create a new project.
Enabling Push Notification Capabilities in Xcode

  • Select “Single View App” in the “iOS” tab to proceed further. 
  • Now,  enter the “Product Name” along with the choice of iPhone app development languages between Objective-C and Swift.
Enabling Push Notification Capabilities

  • Click on the “Signing & Capabilities” tab in order to enable push notifications for your mobile application.
Signing & Capabilities

With this, a mobile application push notification is enabled in your mobile application development.

Xcode, during the build phase, automatically adds the APS environment entitlement after analyzing the certificate type used to sign the mobile app. 

This entitlement involves two values; Development and Production, which implement conditions to the APNs server for iPhone app development on which the mobile device will try to register.


The Development APS environment is used to create a new push notification feature on a running mobile app signed with a development certificate. 


The Production APS environment is used to deploy react native mobile apps in production.

2. How to Configure App to Retrieve the Token

The process of retrieving a token requires configuring a mobile app by installing React Native notifications. 

For that, you use the following code line above your “AppDelegate.m”.

- #import "RNNotifications.h"

After that, add the below code to monitor the notifications in “AppDelegate.m:

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[RNNotifications startMonitorNotifications]; // -> Add this line

return YES;

The following methods are required to support registration to AppDelegate.m:

- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
[RNNotifications didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
[RNNotifications didFailToRegisterForRemoteNotificationsWithError:error];

Next step is to create a “.tsx” file and at the beginning of that file add the following code:

(event: Registered) => {
console.log(' Push Notification token:', event.deviceToken);
(event: RegistrationError) => {
console.log(' Push Notification error', event);

In the above code, Notifications.registerRemoteNotifications() is calling the function registerRemoteNotifications(), which is the method of UIApplication to request the device token to the APNs. After receiving the response, your mobile app dispatches one of the following events:

  • registerRemoteNotificationsRegistered
  • registerRemoteNotificationsFailed

If all steps are done correctly, you will get a unique token that is associated with your mobile device and app in your logs. Now, your device is registered to the APNs, and you can use the retrieved token on the server-side in order to send the notification to your iPhone app.

Set Off a New Notification from a NodeJS Provider Server

As you have already registered your device to APNs and your server has all the information needed in order to target the device, let us go through the creation of a secured connection to APNs from your provider server. After that, you will send a notification payload to your device.

1. Initialize a Trusted Connection to APNs

You can set up APNs connections in two ways:

  • Token-based connection
  • Certificate-based connection

The iPhone app development company recommends the token-based connection because it is faster and stateless. 

For token-based connection, generate and download the key which is used to sign your token on the Apple developer account.

Log in to your Apple developer account and go to the keys section:

Initialize a Trusted Connection to APNs

Here, generate a new public/private key pair. Now, download the private key in order to sign your authentication token.

 Apple will use the public key to validate and authorize your signed token. The generated token must follow JSON Web Token standard, which is an open and industry-standard RFC7519 method that represents claims securely between two parties. The token should comprise of:

  • A header that defines the algorithm used to sign your token and the key identifier that you have retrieved previously.
"alg": "ES256",
"kid": "BG7AK-24J9C-KJ8WE-VG5JU"

  • A payload that contains the ID of your developer’s team or development company and timestamp of the generated token.
"iss": "S4S8383M8Z",
"iat": "TimeStamp of Token Generation"

  • Alas! the last is the signature: which is the result in the payload and base64 encryption of the header with the selected key and the algorithm.

Ok, we are very close. now, proceed further and implement the above process in a NodeJS development environment. 

  1. Create a new NodeJS server. 
  2. Add the JSON Web Token library that offers you all the needed tools required to generate and sign your token. 
  3. The code below will help you to generate the token:
const authorizationToken = jwt.sign(
iss: S4S8383M8Z,
iat: Math.round(new Date().getTime() / 1000),
fs.readFileSync(C:\Desktop\test.P8, "utf8"),
header: {
alg: "ES256",
kid: BG7AK-24J9C-KJ8WE-VG5JU,

2. Create and Send a New Push Notification Payload

You can create a simple push notification payload and that should look like this:

"aps": {
"alert": {
"title": " Push Notification Test",

Now, in the next step, send this payload to APNs and for that, you need to set up an HTTP/2 connection. In order to do so, use the “http2” module, which is provided by NodeJS. The final implementation of your server is as follows:

const app = express()
const port = 3000

const authorizationToken = jwt.sign(
iss: S4S8383M8Z,
iat: Math.round(new Date().getTime() / 1000),
fs.readFileSync(C:\Desktop\test.P8, "utf8"),
header: {
alg: "ES256",
kid: BG7AK-24J9C-KJ8WE-VG5JU,

const http2Client = http2.connect(
IS_PRODUCTION ? 'https://api.push.apple.com' : 'https://api.sandbox.push.apple.com'

app.post('/', (req, res) => {
const request = http2Client.request({
':method': 'POST',
':scheme': 'https',
'apns-topic': com.foreway.PushNotificationTest.com,
':path': '/3/device/' + DEVICE_TOKEN,
authorization: `bearer ${authorizationToken}`,

aps: {
alert: {
title: "Push Notification Test",

request.on('end', () => {
res.send('Push Notification sent !');

app.listen(port, () => {
console.log(`PushNotificationTest app listening at http://localhost:${port}`)

Congrats! Now, you have written a lot of code in order to properly handle the communication with APNs so that we can create features including token refreshing, error handling, and notifications badging. 

In order to make your code simpler. You can use aps-node by running a code:

yarn add aps

After using aps-node, your server code with apn will look like this:

const app = express()
const port = 3000

let provider = new apn.Provider({
token: {
key: C:\Desktop\test.P8,
keyId: BG7AK-24J9C-KJ8WE-VG5JU,
teamId: S4S8383M8Z
production: IS_PRODUCTION

app.post('/', (req, res) => {
var note = new apn.Notification();
note.alert = "Push Notification Test";
note.topic = com.foreway.PushNotificationTest.com;
provider.send(note, DEVICE_TOKEN).then( (result) => {
res.send('Push Notification sent !');

app.listen(port, () => {
console.log(`PushNotificationTest app listening at http://localhost:${port}`)

After implementing all the above-mentioned steps, you will receive a pop-up, which will ask permission to allow the push notifications for the currently running React Native app on your iPhone device.

After this, you need to run your server (yarn start command) and create a post request to http://localhost:3000/. And you will receive a push notification on your iPhone.


Here, We have implemented one of the most worthwhile methods for configuring both a NodeJS server and a React Native app for sending the Push Notification feature on an iPhone app using APNs. This article provides you with deeper knowledge about using iPhone app services using IDs and Keys. There are various other methods used by react native mobile app development companies to send push notifications. However, the method we have used in our article is also valuable and advantageous.
