Why should we learn Swift in 2021

Swift. A powerful open language that anyone can use to build great apps.

Swift is a robust and intuitive programming language from Apple for developing apps for iOS, Mac, Apple TV, and Apple Watch. It's designed to give developers more freedom than ever before. Swift is easy to use and open source. Anyone with an idea can do something fantastic with it.

Developers are already doing it
amazing things with Swift.

Swift is a fast and efficient programming language that provides real-time feedback and can be seamlessly integrated into existing Objective-C code. This allows developers to write safer and more reliable code, save time, and make their apps even better.

Great apps that work with
Swift were created.

More and more developers are embedding Swift Code in their apps. And some even create new apps entirely in Swift.

Better performance for
better apps.

Swift Apps do what their name promises. So z. B. a common search algorithm with Swift is significantly faster.

Swift is being taught.

It's not just developers who have recognized the potential of Swift. Colleges and schools have Swift programming courses on their curriculum and offer free courses on iTunes U. What makes the transition from learning to program to professional programming easier than ever.

Swift is everywhere.
And now open to everyone.

Swift is free and open source and is available to a wide audience of developers, educators, and students under the Apache 2.0 Open Source License. We provide binaries for OS X and Linux that can compile code for iOS, OS X, watchOS, tvOS, and Linux. And to make Swift even more powerful, we've created a community where users can contribute directly to the Swift source code.
