How do I handle multiple windows and scenes on macOS using Swift?

Handling multiple windows and scenes on macOS using Swift can enhance your application's user experience by allowing users to manage different content areas simultaneously. Utilizing the SwiftUI framework along with AppKit, you can create a robust macOS application that can handle these features effectively.

To manage multiple windows, you can create a new window for each scene or view you want to present. In SwiftUI, you can use the `WindowGroup` to manage multiple windows easily. Each window can represent a different `view` or `scene` within your application.

Example Code

import SwiftUI @main struct MultiWindowApp: App { var body: some Scene { WindowGroup { ContentView() } } func openNewWindow() { let newWindow = NSWindow( contentRect: NSMakeRect(0, 0, 600, 400), styleMask: [.titled, .closable, .resizable], backing: .buffered, defer: false ) newWindow.center() newWindow.setFrameAutosaveName("New Window") newWindow.contentView = NSHostingView(rootView: NewWindowView()) newWindow.makeKeyAndOrderFront(nil) } } struct ContentView: View { var body: some View { Button("Open New Window") { if let appDelegate = NSApplication.shared.delegate as? AppDelegate { appDelegate.openNewWindow() } } } } struct NewWindowView: View { var body: some View { Text("This is a new window!") } }
