UIComposerStudio Help

Visual SwiftUI app builder for macOS

Reference notes: UIComposerStudio is a visual SwiftUI builder for creating iOS app UIs on macOS. It supports project-style code generation, local workspace save/load, screen flow setup, tab shell preview, and Swift export that you can continue in Xcode or Swift Playgrounds.

Most important: You can create Swift iOS app code without writing code and without owning an iPhone. Build visually on your Mac, preview in device frames, then copy or export Swift files.
