This was release noted here: https://developer.apple.com/documentation/macos-release-notes/macos-15-release-notes (Search 127626852) Behavior was changed because the composition is undefined on iOS and was undefined on macOS, but happened to work in some cases. This change was made behind a link check, so hopefully you are only seeing this when compiling against the newest Sequoia toolchains. View-destination links (e.g. NavigationLinks that take a View as their destination) and value-destination links (e.g. NavigationLinks that take a value argument) cannot be mixed. By attaching an id to the link, you are wiring the link up to the Lists selection, and thus trying to drive navigation that way. The correct way to do this in releases including and prior to iOS 15 and macOS 18 is by switching over the selection in the NavigationSplitView's subsequent column: NavigationSplitView { List(selection: $selection) { NavigationLink(Value-destination link, value: 5) } } detail: { if let selection { SelectedDest

I want the wallpapers gone because I dislike them greatly. I have dozens of much higher quality (as wallpapers go) because they are simple and non-distracting, non-entertainment. I've been struggling to get rid of them for a long time. Additionally, the Sonoma wallpaper system is broken in many ways. The worst is that it keeps putting back that default wallpaper of some vineyard somewhere. I think I finally found an answer, although it is terribly kludgy. WARNINGS BEFORE YOU START THIS, BE AWARE OF THESE THINGS; READ THEM ALL If all you want is to delete the downloaded live wallpapers to save space THIS IS NOT THE WAY. Go find other posts for that. If you want to be rid of the downloaded wallpapers AND stupid selection thumbnails for all those stupid wallpapers, then find a different post for deleting, AND do the steps below. The Sonoma wallpaper selection pane (in Settings) might not work. Ever. Sometimes it does. Because of the above, if you can, set some wallpapers that you do like (wallpapers of your own

@vladimirs NavigationSplitView is a top level navigation container and it's meant to be used without being wrapped in another navigation container. You can embed a NavigationStack in a column of a NavigationSplitView not the other way around since a navigation split view collapses into a single stack on iPhone. If you'd like to learn more about navigation structures, you could review The SwiftUI cookbook for navigation WWDC session Could you elaborate on why you have the NavigationSplitView inside stack and what you're trying to achieve ?

Although Apple introduced .toolbar(removing: .sidebarToggle) finally, users can still drag the divider to change the column width and hide the side bar on macOS, and since sidebar toggle button is removed, users could never get back. In Sonoma Xcode15, developers have to use something like this: .introspect(.navigationSplitView, on: .macOS(.v13,.v14,.v15)) { splitview in if let delegate = splitview.delegate as? NSSplitViewController { delegate.splitViewItems.first?.canCollapse = false } } But it fails to work on Sequoia with Xcode16. Developers have to search around again to make it work just like the built-in Settings App, it's a shame.

Ditto here. All the other advice on the subject of struct-typed model attributes asserts the struct must be Codable and it stored in a single column. The evidence shows the struct's properties are stored as individual columns, spreading the structure out and using some truly unexpected Encoder/Decoder that's not JSON. For instance, I defined struct ComplexNumber: Codable { var real: Double var imaginary: Double } and @Model final class Item { var timestamp: Date var number1: ComplexNumber var number2: ComplexNumber and got this in SQLite: This works fine when fetching the records, but in my app it fails to decode when some of the struct's properties are Optional. I can write decoder() to deal with the optionals, but apparently SwiftData's Decoder can't cope. I suppose there's some similar limitation for Dictionary properties.

Try this: In Script Editor, create a new script like so: display dialog Hello Cruel World! buttons {OK} default button OK Save it as an application. Launch it from the Finder. Run Activity Monitor and, in the CPU tab, look for the value in the Kind column. It should show Apple (for Apple silicon). What do you see?

@marudavid I am not able to reproduce your issue using the following sample code. There is a default background color always on both Xcode 15 and Xcode 16.1 Beta. It is possible you are using some type of ViewModifier that is causing this. The following works fine. import SwiftUI struct Icon: Identifiable { var id: String var color: Color } struct ContentView: View { let icons = [ Icon(id: figure.badminton, color: .red), Icon(id: figure.fencing, color: .orange), Icon(id: figure.gymnastics, color: .green), Icon(id: figure.indoor.cycle, color: .blue), Icon(id: figure.outdoor.cycle, color: .purple), Icon(id: figure.rower, color: .indigo), ] @State private var selected: Icon? var body: some View { LazyVGrid(columns: [.init(.adaptive(minimum: 100, maximum: 300))]) { ForEach(icons) { icon in Button { selected = icon } label: { Image(systemName: icon.id) } .foregroundStyle(icon.color.gradient) .font(.system(size: 100)) } } .fullScreenCover(item: $selected, content: { icon in DestinationView(icon: icon, anim
