Swift Playgrounds lets you build a complete iOS app from scratch, right on your iPad. You get to draw upon Apple’s powerful SwiftUI framework, you can pull in libraries that other people have written, and if you want you can even move your project over to your Mac and continue it in Xcode, Apple’s full-blown code editor.
At WWDC21 Apple revealed that Swift Playgrounds was getting a huge upgrade to allow us to build complete SwiftUI apps, including not only a live preview of our work but also the ability to ship direct to the App Store.
Swift’s standard library is packed with types and functions to solve the most common code problems quickly and efficiently, but it doesn’t cover everything. So, for more advanced needs we need to turn to Swift Algorithms: Apple’s open source package of sequence and collection algorithms, tuned for maximum performance and flexibility.
