The powerful programming language that is also easy to learn.

Swift is a powerful and intuitive programming language for iOS, iPadOS, macOS, tvOS, and watchOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast and is super-dynamic.

Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Even better, you don’t even need to type semi-colons. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases.

Memory is managed automatically using tight, deterministic reference counting, keeping memory usage to a minimum without the overhead of garbage collection.


  • Swift has many other features to make your code more expressive:
  • Generics that are powerful and simple to use
  • Protocol extensions that make writing generic code even easier
  • First class functions and a lightweight closure syntax
  • Fast and concise iteration over a range or collection
  • Tuples and multiple return values
  • Structs that support methods, extensions, and protocols
  • Enums can have payloads and support pattern matching
  • Functional programming patterns, e.g., map and filter
  • Native error handling using try / catch / throw

Can I learn Swift on Windows?

You can learn Swift on Windows, but not as a part of Xcode or iOS. Swift on its own is just a programming language, it's the Cocoa Touch SDK you use to build iOS apps. If you want to learn how to code iOS apps, you'll eventually have to work with Xcode – that's the only way to build iOS apps.

Is Swift in demand?

Swift remains in the top ten most demanded programming languages, while iOS apps are popular. According to Statista, in 2019, 1.84 million mobile apps were available for download on the App Store. And the number of iOS applications is growing every year.

Is Swift like Java?

Swift vs java are both different programming languages. They both have different methods, different code, usability, and different functionality. Swift is more useful than Java in the future. But information technology java has one of the best languages.

What do I need to program in Swift?

The most straightforward way to code Swift is with a Mac and Xcode. You'll need a Mac computer to install Xcode, like a MacBook, or you can try to install macOS on PC. You can download and install Xcode on your Mac via the App Store. You can also download Xcode via

Is Swift worth learning 2022?

It remains one of the most in-demand languages of 2022, as iOS applications are increasing in popularity around the world. Swift also is easy to learn and supports almost everything from Objective-C, so it's an ideal language for mobile developers.



Kotlin is a general purpose, free, open source, statically typed “pragmatic” programming language initially designed for the JVM (Java Virtual Machine) and Android that combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support.

Kotlin allows writing less code


Less code, when done right, results in fewer bugs. When you let the framework take care of certain mundane aspects of coding, you can focus on more important things. Kotlin is all about high readability, simplicity, and the facilitation of the app development process.

Some of the main goals of Kotlin's development team are rapidly becoming some of the biggest 

advantages of using Kotlin over Java. Kotlin is:

  • efficient and presents a familiar development tooling that is meant to boost developers' productivity;
  • a good compiler;
  • a seamless integration with the existing infrastructure (Kotlin's compatible with all Java frameworks and libraries, and it's designed to integrate easily with Marven and Gradle build systems, as well); and, provides an enhanced run-time performance.

Kotlin FAQs

What is Kotlin?

Kotlin is an open-source statically typed programming language that targets the JVM, Android, JavaScript and Native. It’s developed by JetBrains. The project started in 2010 and was open source from very early on. The first official 1.0 release was in February 2016.

What is the current version of Kotlin?

The currently released version is 1.6.10, published on December 14, 2021.


Is Kotlin free?

Yes. Kotlin is free, has been free and will remain free. It is developed under the Apache 2.0 license and the source code is available on GitHub.


Is Kotlin an object-oriented language or a functional one?

Kotlin has both object-oriented and functional constructs. You can use it in both OO and FP styles, or mix elements of the two. With first-class support for features such as higher-order functions, function types and lambdas, Kotlin is a great choice if you’re doing or exploring functional programming.


What advantages does Kotlin give me over the Java programming language?

Kotlin is more concise. Rough estimates indicate approximately a 40% cut in the number of lines of code. It’s also more type-safe, e.g. support for non-nullable types makes applications less prone to NPE’s. Other features including smart casting, higher-order functions, extension functions and lambdas with receivers provide the ability to write expressive code as well as facilitating creation of DSL.

Is Kotlin compatible with the Java programming language?

Yes. Kotlin is 100% interoperable with the Java programming language and major emphasis has been placed on making sure that your existing codebase can interact properly with Kotlin. You can easily call Kotlin code from Java and Java code from Kotlin. This makes adoption much easier and lower-risk. There’s also an automated Java-to-Kotlin converter built into the IDE that simplifies migration of existing code.


What can I use Kotlin for?

Kotlin can be used for any kind of development, be it server-side, client-side web and Android. With Kotlin/Native currently in the works, support for other platforms such as embedded systems, macOS and iOS is coming. People are using Kotlin for mobile and server-side applications, client-side with JavaScript or JavaFX, and data science, just to name a few possibilities.


Can I use Kotlin for Android development?

Yes. Kotlin is supported as a first-class language on Android. There are hundreds of applications already using Kotlin for Android, such as Basecamp, Pinterest and more. For more information check out the resource on Android development.


Can I use Kotlin for server-side development?

Yes. Kotlin is 100% compatible with the JVM and as such you can use any existing frameworks such as Spring Boot, vert.x or JSF. In addition there are specific frameworks written in Kotlin such as Ktor. For more information check out the resource on server-side development.


Can I use Kotlin for web development?

Yes. In addition to using for backend web, you can also use Kotlin/JS for client-side web. Kotlin can use definitions from DefinitelyTyped to get static typing for common JavaScript libraries, and it is compatible with existing module systems such as AMD and CommonJS. For more information check out the resource on client-side development.

Can I use Kotlin for desktop development?

Yes. You can use any Java UI framework such as JavaFx, Swing or other. In addition there are Kotlin specific frameworks such as TornadoFX.


Can I use Kotlin for native development?

Yes. Kotlin/Native is available as a part of Kotlin project. It compiles Kotlin to native code that can run without a VM. It is still in beta, but you can already try it on popular desktop and mobile platforms and even some IoT devices. For more information, check out the Kotlin/Native documentation.


What IDEs support Kotlin?

Kotlin is supported by all major Java IDEs including IntelliJ IDEA, Android Studio, and Eclipse. In addition, a command line compiler is available and provides straightforward support for compiling and running applications.


What build tools support Kotlin?

On the JVM side, the main build tools include Gradle, Maven, Ant, and Kobalt. There are also some build tools available that target client-side JavaScript.


What does Kotlin compile down to?

  • When targeting the JVM, Kotlin produces Java compatible bytecode.
  • When targeting JavaScript, Kotlin transpiles to ES5.1 and generates code which is compatible with module systems including AMD and CommonJS.
  • When targeting native, Kotlin will produce platform-specific code (via LLVM).


Which versions of JVM does Kotlin target?

Kotlin lets you choose the version of JVM for execution. By default, the Kotlin/JVM compiler produces Java 8 compatible bytecode. If you want to make use of optimizations available in newer versions of Java, you can explicitly specify the target Java version from 9 to 17. Note that in this case the resulting bytecode might not run on lower versions.

Is Kotlin hard?

Kotlin is inspired by existing languages such as Java, C#, JavaScript, Scala and Groovy. We've tried to ensure that Kotlin is easy to learn, so that people can easily jump on board, reading and writing Kotlin in a matter of days. Learning idiomatic Kotlin and using some more of its advanced features can take a little longer, but overall it is not a complicated language.
