SwiftUIPhone

Run a SwiftUI app (or any SwiftUI view) in an iPhone Simulator "wrapper", directly on macOS!

To be clear, this is not an iPhone Simulator (nor any sort of emulation thereof). Rather, for those of us who took care to write our iOS apps without leaning on any platform-specific libraries (e.g. UIKit), you can think of this as your reward: a way to build that app for macOS and run it at light speed (compared to an actual iPhone Simulator, that is) directly on any Mac, no Xcode or dev tools required.

Compatibility

SwiftUIPhone is compatible with applications targeting macOS 11+.

    @SceneBuilder var body: some Scene {
        WindowGroup {
            VStack(alignment: .center) {
                Button("Launch SwiftUIPhone") { launch() }
            }.padding()
        }
    }
    
    func launch() {
        let window = NSWindow(
            contentRect: NSRect(x: 0.0, y: 0.0, width: 400.0, height: 809.0),
            styleMask: [.titled, .closable, .miniaturizable],
            backing: .buffered,
            defer: false
        )
        
        let view = SwiftUIPhone(
            rootView: AnyView(
                VStack(alignment: .center) {
                    Text("This is the root view of my app")
                }
                .background(colorScheme == .dark ? Color.black : Color.white)
            )
        )
        
        window.titlebarAppearsTransparent = false
        window.hasShadow = false
        window.isOpaque = false
        window.backgroundColor = NSColor.clear
        window.center()
        window.setFrameAutosaveName("\(appName).MainWindow")
        window.title = appName
        window.isReleasedWhenClosed = false
        window.contentView = NSHostingView(rootView: view)
        window.makeKeyAndOrderFront(nil)
    }
}
