SwiftUI
Short answerSwiftUI is Apple's declarative UI framework: you describe views as functions of state and it updates the screen when the state changes. It runs on iPhone, iPad, Mac, Watch and Vision Pro.
Why it matters
It is the fastest way to build a native iOS app today, and the code is plain text that builds from a script, which makes it friendly to CI and AI coding agents.
Our number
Our 20+ iPhone apps are built with SwiftUI (plus SpriteKit or Metal in the games), written on Windows and compiled on cloud macOS runners.
