What is Swift?
Swift is a multi-paradigm, compiled programming language invented by Apple for its own operating systems to make it easy for Apple devices. iOS, iPadOS, tvOS, Apple smart wears operating system, and every other device. In short, Swift is a language for developing all the applications on all Apple devices.
Swift was inspired by Objective-C, C#. Swift was mainly developed to work with Apple’s Cocoa and Cocoa Touch. Swift has amazing features to address common but problematic programming errors smoothly. Swift can be executed with C, C++, and Objective-C in the same program. Swift is the best language for mobile app development for iOS.
What is Kotlin?
The big question- Swift vs Kotlin
Purpose of Development
Swift was built for iPhone app development, whereas Kotlin was for android app development. Apart from, the purpose of development they both have very different syntax and features for mobile app development.
Difference in the Language Norms
- Swift “Enums” are more effectual.
- Swift uses no data class.
- Swift does not support delegated classes or delegated properties.
- Swift has no provision for annotations.
- All Kotlin classes are “final” by default, the developer has to use a specifier as per the need.
- Kotlin does not support struct or passing data by value.
- Kotlin uses no tuples.
- Kotlin doesn’t support type alias.
- Kotlin doesn’t have a guard statement.
Swift uses ARC or Automatic Reference Counting for memory management. Kotlin uses the Garbage Collection memory management approach.
Kotlin code is interoperable with Java, the sole reason to develop Kotlin is to have an interoperable language with Java. Java and Kotlin classes can be in the same file and the application will run smoothly. Likewise, Swift coexists with Objective-C code.
Let summarize what we have learned so far, Kotlin is a programming language for used Android app development whereas Swift is used for iPhone application development. Both Kotlin and Swift are built on top of the modern programming approach and software design pattern. Both languages provide several inbuilt functions defined in an extensive list of libraries and amazing features to the mobile app development companies.
Like always there are both similarities and differences between the two languages. Both Kotlin and Swift are evolving in terms of performance, programming advancement, and security. As both, languages have their own perks but they both are great in their own ways like Kotlin for Android and Swift for iOS.
