Get notified when a file gets opened and closed (macOS)

I would like to get notified, when a specific file gets opened or closed by another application. I tried different things like DispatchSource, FSEvents and kqueue, but nothing worked. The only option so far is searching for all process ids, that accesses the file with proc_listpidspath (or with the command line tool lsof). Unfortunately I need to use a Timer for this. But checking i. e. every second will need a lot of CPU, so I'm curious, if there is a built in notification in macOS?

.onChange with ScenePhase not working

Hi, I created a new project with Xcode 12 beta on Big Sur beta. I changed the code in the @main-wrapper to this: 	@Environment(\.scenePhase) private var scenePhase var body: some Scene { WindowGroup { ContentView() } .onChange(of: scenePhase) { (newScenePhase) in print(newScenePhase) } } If I start the application (either macOS or iOS), nothing happens, nothing will be printed in the onChange. Do I miss something?

Use tabs like in Safari

Is it possible in SwiftUI to have a tabbed interface like in Safari? The videos of the WWDC only shows that you can group several windows on macOS to tabs, but is this possible in iPadOS as well and can I create tabs programmatically?
