Hello, I'm having trouble understanding Focus in SwiftUI on macOS for my application. I have distilled it down to a small reproducible case here. struct ContentView: View {   struct Item : Identifiable, Equatable, Hashable {     let id : Int     let url : URL     @ViewBuilder var view : some View {       if id % 2 != 0 {         AsyncImage(url: url)       } else {         Image(systemName: "questionmark.diamond")       }     }   }   struct DetailView : View {     @Binding var item: Item?     var items : [Item] {       if let item {         return [item, item]       }       return []     }     var body: some View {       List(items) { item in         item.view       }     }   }   var url : URL {     return URL(string: "https://is1-ssl.mzstatic.com/image/thumb/Music/4c/aa/6f/mzi.cnwthgxu.jpg/900x900bb.jpg")!   }   var items : [Item] {     var a : [Item] = []     for i in 0..<10 {       a.append(Item(id: i, url: url))     }     return a   }   @State private var selectedItem : Item?   var body: some View {     NavigationSplitView {       List(items, selection:$selectedItem) { item in         NavigationLink(value: item) {           Text("\(item.id)")         }       }     } detail: {       DetailView(item: $selectedItem)     }   } } If you click on an even row, the behavior is as expected. The side List highlights. Press the Tab key. Nothing highlights, but I assume focus is in the DetailView. Press the Tab key a second time. It will now highlight the focus on the side bar show/hide button in the toolbar. Press the Tab key again, and it will go back to the side view list’s selection. If you click on an odd row, the behavior is not as expected. The side List highlights. Press the Tab key. Nothing highlights, but I still assume focus is in the DetailView. Press the Tab key a second time. This time, instead of focusing the sidebar show/hide button, nothing highlights again. I still assume focus is in the DetailView, but it is not clear what. Now press the Tab key again, and the highlight focuses on the sidebar show/hide button. I’m confused why two Images (one from Image(systemName:) and the other from an URL via AsyncImage) have different Tab key behavior. Why does AsyncImage seem to capture the two images, while the SF Symbols Images do not? Why does anything in the DetailView capture focus at all? Thanks for any tips! FB12044843

The new Map builder SwiftUI is awesome. Does it support cluster annotations? I have opened FB12244017. Thank you very much!

Hello, On macOS I can use the defaults command line tool to reset or modify @AppStorage data outside the application. Where is @SceneStorage data stored? Alternately, how do I reset my application back to "it's not yet stored"? Thank you for any tips!

Hello, When I use xcstrings in my app, and I have my scheme's localization debugging enabled (when it renders all caps for any non-localized text). Prior to converting to xccstrings, my app shows non caps text for everything. After I convert to xcstrings, some of my app shows caps text for some items. I can see the keys in the xccstrings that I expect, so I do not think it is a bug in the conversion. Could it be a bug in the renderer somehow? FB13261276 Thanks! -- Greg

Hello, I use CLGeocoder to get the CLLocationCoordinate2D and CLRegion for an address. Now that this is deprecated in OS 26, I don't see a replacement for that property on MKMapItem via MKMapItemRequest and PlaceDescriptor. I've filed FB19027378 on this issue. Basically I have some addresses that have a street address, and others that just have a city. With CLGeocoder, when geocoding just the city, the CLRegion was set such that I could show my map zoomed out just right. I'm not sure how to do that now. Thanks!

I would like to have an AppEntity with a Property that is a Date, which is only the date, not the time. ie the equivalent of 09/14/2025, not 09/14/2025 09:00 UTC How would I model this? How would I create an EntityPropertyQuery for this? If I add QueryProperties they have the UI in Shortcuts pick a time too. Thanks!

Hello, I am running a virtual machine on my Apple Silicon Mac, using the sample Xcode project provided by Apple last year. I have Ventura 13.4 installed on on the host and the VM. I try to enter my Apple ID credentials in "Sign In with Apple ID" in the VM so I may then update this VM to Sonoma. I am sure I am getting my password correct. I cannot log in. Please see the screen shot. Am I supposed to be able to do this? I can log into developer.apple.com within the VM OK. Thank you. FB12263051

If I convert my SPM from .strings to .xcstrings it will fail to build when using swift build. It builds from Xcode 15. My UI code uses bundle: .module so the localized strings are found properly. See https://github.com/bolsinga/site/pull/685 for the change (as well as the action log). Does SPM build somehow not know that .xcstrings in a Resource directory make the build a "bundle build"? I filed FB13261704 Thanks!

I'm using iCloud Music Library. I’m using macOS 14.1 (23B74) and iOS 17.1. i’m using MusicKit to find songs that do not have artwork. On iOS, Song.artwork will be nil for items I know do not have artwork. On macOS, Song.artwork is not nil. However when the songs are shown in Music.app, they do not have Artwork. Is this expected? Alternately, is there a more correct way to determine that a Song has no Artwork? I have also filed FB13315721. Thank you for any tips!

Hello, I have a SwiftUI application that uses NavigationSplitView. It's working great on iOS, iPad, and macOS. I decided to give it a try on tvOS. After it builds, it will not allow user interaction on the NavigationSplitView's sidebar. I've tried various view focus modifiers without any success. I'd also expect this to "just work" as default behavior. I have filed FB13447961 on this issue. Here is a distillation of the code that demonstrates the problem. Any ideas? Thank you. enum Category : String, CaseIterable { case first case second case third } enum Detail : String, CaseIterable { case one case two case three } struct DetailView : View { let category : Category? var body: some View { if let category { Text(category.rawValue) List(Detail.allCases, id: \.self) { detail in NavigationLink(value: detail) { Text(detail.rawValue) } } } else { Text("Select Category") } } } struct ContentView: View { // NOTE: If this category is set to something, it will show that category's detail. // The problem is that the NavigationSplitView sidebar does not have, nor does not // seem to be able to get focus. @State var category: Category? @State var path : [Detail] = [] var body: some View { NavigationSplitView { List(Category.allCases, id: \.self, selection: $category) { category in Text(category.rawValue) } } detail: { NavigationStack(path: $path) { DetailView(category: category) .navigationDestination(for: Detail.self) { detail in Text("\(detail.rawValue)") } } } } } #wwdc2023-10162 #wwdc20-10042

I have an app that gets data from Music.app with both the iTunesLibrary and MusicKit. iTunesLibrary has ITLibArtist.sortName and ITLibAlbum.sortTitle and ITLibAlbum.sortAlbumArtist. I can’t seem to find an equivalent in MusicKit. How are those properties obtained using MusicKit? Thanks. FYI I have filed FB15554956 on this. You also may see my code at https://github.com/bolsinga/itunes_json

Hello, CLServiceSession is not on macOS. Does anyone have a drop-in CLServiceSession like replacement for macOS that wraps CLLocationManager? I would like to migrate to the latest for the other platforms. FWIW I filed FB17910626 Thanks!

Hello, I have a script that I can run with launchd. I want it to be able to do some git operations. If I run my script manually (outside of launchd) things work great. If I run it within launchd, it seems to have issues with the sandboxing. git says: error Unable to read current working directory: Operation not permitted Here are the .plist and the .sh. Does anyone have any ideas what I can do? git seems to have many options about reading its configuration files; I assume that is what is going on here.

Hello, This code has a NavigationSplitView, whose sidebar is a List and its detail contains a NavigationStack. It is controlled by two @Observable properties, a selection and a path. The path shown in the detail depends upon the selection in the List. If I programmatically change the selection and path, the path will be set, but via SwiftUI backtraces (pasted below), it will clear out my path. This makes my code lose state. What am I doing wrong? Is this a bug? I'm using Xcode16 running against the iOS 18 simulator (although this also happens with iOS17). To reproduce, Launch the App, Note that you are on the "first" selection. Tap "Nav Path: Path: second-100". You'll go to the "second" selection, but the path will be empty. If you place a breakpoint when the $path is cleared, you'll see it is being cleared by SwiftUI. Backtrace when the path is emptied: (lldb) bt * thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 2.1 * frame #0: 0x00000001043295c0

Is there a way to share a SwiftUI App's @Observable model into a CPTemplateApplicationSceneDelegate ? Is there an incantation to go from the UIApplicationDelegate via @UIApplicationDelegateAdaptor to the UISceneDelegate for CarPlay via a userInfo? I can't seem to figure it out. Otherwise I have to use a shared global, and I'd prefer not to have to do it this way. Any ideas? Thanks!
