About SwiftUI
SwiftUI is Apple's framework for building user interfaces with Swift. You describe what the interface should look like, and the system handles updates and animations.
What it does
SwiftUI lets developers build apps across Apple platforms with one set of tools and APIs. Views are described in code, so the interface updates when the data changes. Animations can be added to most controls with a few lines of code. SwiftUI works alongside UIKit and AppKit, so teams can adopt it one screen at a time.
Key features
- Declarative syntax for user interfaces
- Live previews inside Xcode
- Simple animations with few lines of code
- Works alongside UIKit and AppKit
- One set of APIs across Apple platforms
Who it's for
iOS and Mac developers who want less interface code, and teams that already use Swift. It suits new apps as well as new screens added to existing apps.
Pricing and good to know
SwiftUI is free. It is part of Apple's developer tools and runs inside Xcode. Apps built with it are published through Apple's developer program, which has its own membership requirements.
