Swift
Swift — Apple’s powerful and intuitive programming language — now features built-in concurrency support. This means developers can more easily write code that does work in parallel, which is key to building apps that are responsive to user input, while doing more work in the background. With concurrency in Swift, developers can write fast, modern, safe code with fewer mistakes, and take full advantage of the powerful multicore silicon across Apple’s devices.
SwiftUI has re-invented user interface development by making it easier to develop great-looking apps with as little code as possible. Now SwiftUI takes a huge step forward, helping developers bring more great experiences to all their users. This includes enhancements for improving list views, search experiences, in-app accessibility features, multicolumn tables and so much more.
Swift Playgrounds is a great way to learn to code on a Mac or iPad. With Swift Playgrounds 4, coming later this year, users will be able to create the visual design of an app with SwiftUI. App projects can be opened and edited in Swift Playgrounds or in Xcode, and when they’re ready, users can build a real app and submit it directly to the App Store from their iPad.
