What is SwiftUI?
SwiftUI is Apple's framework for building the screens of an app in Swift. Instead of placing every button by hand, you describe what a screen should show, and SwiftUI draws it and keeps it up to date as the data changes. Apple introduced it in 2019, and it works across iPhone, iPad, Mac, Apple Watch and Apple TV.
More about SwiftUI
Because SwiftUI is Apple's own toolkit, apps built with it get the system's controls, fonts, Dark Mode, Dynamic Type and accessibility features with little extra work. New iOS designs reach SwiftUI apps first: on iOS 26, a SwiftUI tab bar takes on the Liquid Glass look.
SwiftUI with Borel
Every app Borel makes is a SwiftUI app. Borel's AI writes the screens in SwiftUI, Xcode builds them on Borel's Mac, and you try the result on a live iPhone Simulator in your browser. Ask for a change in plain words, and Borel edits the SwiftUI code for you.
