In SwiftUI for macOS, how can I animate the transition from one Tab to another Tab within TabView when the selection changes? In AppKit, we can do the following: let tabViewController = NSTabViewController() tabViewController.transitionOptions = [.crossfade, .allowUserInteraction] How can I achieve the same crossfade effect when using TabView?

In SwiftUI for macOS, when implementing a DragGesture inside a ScrollVIew, how can I implement auto-scrolling when the mouse is not actively moving? In AppKit, this would normally be done with a periodic event so that auto-scrolling continues to take place even if the user isn't actively moving the mouse. This is essential behaviour when implementing something like a drag-to-select gesture. NSView.autoscroll(with: NSEvent) -> Bool Is there anything in SwiftUI or ScrollView to accomplish this behaviour?

Is there a way to configure the style and toolbar of the macOS window that Xcode uses in #Preview? I am working on a macOS application and want to preview some SwiftUI views within different window styles, toolbar styles and window title/subtitle visibilities. Some of the modifiers to control the look-and-feel of a window are actually Scene Modifiers, not View Modifiers: .windowStyle .windowToolbarLabelStyle .windowToolbarStyle But #Preview does not accept Scenes, so I can't apply these modifiers: // Error, not a view modifier. #Preview { ContentView() .windowStyle(...) } // Error, Window is not supported in #Preview. #Preview { Window("Browser", id: "browser") { ContentView() } } If I give my ContentView a .toolbar(...), Xcode's Preview will correctly show a window with a toolbar, but not necessarily in the style I want. Is there a way to apply the Scene Modifiers to #Preview so that I can see how they affect the window's chrome and toolbar?
