Unable to display SwiftUI View Previews in a Static Framework target
Hello, I am currently encountering an issue where SwiftUI View Previews cannot be displayed when the View is defined in a Static Framework target. This issue only occurs under specific conditions. Environment Xcode: 16.2 Scheme Structure: MainApp Test Target: TestHogeFeature Test Setting: Gather coverage (Code coverage collection) enabled(all) Target Structure: MainApp (Application target) Dependencies: [HogeFeature, Core] HogeFeature (Static Framework target) Dependencies: [Core] Core (Framework target) Dependencies: None TestHogeFeature (Unit test target) Dependencies: [HogeFeature] Summary I am currently working on a SwiftUI-based project and have encountered an issue where Previews fail to display under specific conditions. Below are the details: Issue In the MainApp scheme, when the code coverage collection setting (Gather coverage for) is enabled, Previews for SwiftUI Views within the HogeFeature (Static Framework) target fail to display correctly. However, the issue is resolved by taking one of the following actions: Change HogeFeature from a Static Framework to a Dynamic Framework. Remove the build setting MACH_O_TYPE: staticlib Disable the Gather coverage setting in the MainApp scheme. I have attached the actual error log from the failed Preview. preview error log Questions Why does this issue occur only when using a Static Framework with code coverage enabled? Is there any way to resolve this issue while maintaining the current configuration (Static Framework with code coverage enabled)? I would appreciate any advice or insights regarding the cause and potential solutions.

*** -colorSpaceName not valid
Here is a relatively simple code fragment: let attributedQuote: [NSAttributedString.Key: Any] = [ .font: FieldFont!, .foregroundColor: NSColor.red] let strQuote = NSAttributedString.init(string:"Hello World", attributes:attributedQuote) strQuote.draw(in: Rect1) It compiles without an issue, bur when I execute it, I get: "*** -colorSpaceName not valid for the NSColor <NSColor: 0x6000005adfd0>; need to first convert colorspace." I have tried everything I can think of. What's going on?

NSHostingController menu not activated
I'm attempting to write a macOS version of https://stackoverflow.com/a/74935849/2178159. From my understanding, I should be able to set the menu property of an NSResponder and it will automatically show on right click. I've tried a couple things: A: set menu on an NSHostingController's view - when I do this and right or ctrl click, nothing happens. B: set menu on NSHostingController directly - when I do this I get a crash Abstract method -[NSResponder setMenu:] called from class _TtGC7SwiftUI19NSHostingControllerGVS_21_ViewModifier_...__. Subclasses must override C: manually call NSMenu.popup in a custom subclasses of NSHostingController or NSView's rightMouseDown method - nothing happens. extension View { func contextMenu(menu: NSMenu) -> some View { modifier(ContextMenuViewModifier(menu: menu)) } } struct ContextMenuViewModifier: ViewModifier { let menu: NSMenu func body(content: Content) -> some View { Interaction_UI( view: { content }, menu: menu ) .fixedSize() } } private struct Interaction_UI<Content: View>: NSViewRepresentable { typealias NSViewType = NSView @ViewBuilder var view: Content let menu: NSMenu func makeNSView(context: Context) -> NSView { let v = NSHostingController(rootView: view) // option A - no effect v.view.menu = menu // option B - crash v.menu = menu return v.view } func updateNSView(_ nsView: NSViewType, context: Context) { // part of option A nsView.menu = menu } }

How to override NSWindow in a pure SwiftUI Application
So I am looking to use a custom NSWindow application (so I can implement some enhanced resizing/dragging behavior which is only possible overriding NSWindow). The problem is my whole application is currently SwiftUI-based (see the project here: https://github.com/msdrigg/Roam/blob/50a2a641aa5f2fccb4382e14dbb410c1679d8b0c/Roam/RoamApp.swift). I know there is a way to make this work by dropping my @main SwiftUI app and replacing it with a SwiftUI root view hosted in a standard AppKit root app, but that feels like I'm going backwards. Is there another way to get access (and override) the root NSWindow for a SwiftUI app?

SwiftUI: How do you do CoreData backup and restore?
Hi, I am trying to create a local backup + restore when using SwiftUI and CoreData but I am facing errors left and right. the latest error I am stuck on is: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'executeFetchRequest:error: A fetch request must have an entity.' Here is what am trying to do: Creating a backup (already solved using NSPersistentStoreCoordinator.migratePersistentStore(_:to:options:type:)) Create a new NSPersistentContainer and call its NSPersistentContainer.loadPersistentStores(completionHandler:) (already solved, load is successful) Update the .environment(.managedObjectContext, viewModel.context) so that SwiftUI uses the new context. (HERE is where the error appears) Any help would be appreciated. Here is some sample code of SwiftUI part of the main view: class ViewModel: ObservableObject { @Published var context: NSManagedObjectContext } @main struct MyApp: App { @StateObject var viewModel: ViewModel var body: some Scene { WindowGroup { ContentView() .environment(\.managedObjectContext, viewModel.context) } } }

PhoneSceneDelegate white screen
I am currently implementing multiple scenes in my React Native / Swift application (one scene for the phone and one scene for CarPlay). I am facing an issue where one scene renders completely white (on the iPhone) but I can see in the console that the code is running (for example if I add a console.log to the App.tsx I can see that console log happen in XCode). There are no errors when building the app in XCode, and testing with the simulator CarPlay appears to render the correct output, but there is no component being rendered on the simulated phone screen (just white).

I am very new to building apps with React Native and Swift so could do with some support.

Change anchor position of view for the tvOS focus engine
I'm developing a grid of focusable elements in SwiftUI with different sizes for tvOS (similar to a tv channel grid). Because the Focus Engine calculates the next view to focus based on the center of the currently focused view, sometimes it changes focus to an unexpected view. Here's an example: Actual: Expected: Is it possible to customize the anchor point from which the focus engine traces a ray to the next view? I would prefer the leading edge in my case.

Button Behavior between fullScreenCover and sheet
The behavior of the Button in ScrollView differs depending on how the View is displayed modally. When the View is displayed as a .fullScreenCover, if the button is touched and scrolled without releasing the finger, the touch event is canceled and the action of the Button is not called. On the other hand, if the View is displayed as a .sheet, the touch event is not canceled even if the view is scrolled without lifting the finger, and the action is called when the finger is released. In order to prevent accidental interaction, I feel that the behavior of .fullScreenCover is better, as it cancels the event immediately when scrolling. Can I change the behavior of .sheet? Demo movie is here: https://x.com/kenmaz/status/1896498312737611891 Sample code import SwiftUI @main struct SampleApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { @State private var showSheet = false @State private var showFullScreen = false var body: some View { VStack(spacing: 16) { Button("Sheet") { showSheet.toggle() } Button("Full screen") { showFullScreen.toggle() } } .sheet(isPresented: $showSheet) { SecondView() } .fullScreenCover(isPresented: $showFullScreen) { SecondView() } .font(.title) } } struct SecondView: View { @Environment(\.dismiss) var dismiss var body: some View { ScrollView { Button("Dismiss") { dismiss() } .buttonStyle(MyButtonStyle()) .padding(.top, 128) .font(.title) } } } private struct MyButtonStyle: ButtonStyle { func makeBody(configuration: Self.Configuration) -> some View { configuration .label .foregroundStyle(.red) .background(configuration.isPressed ? .gray : .clear) } }

LazyHstack in SwiftUI not supporting varying height views
In SwiftUI I want to create a list with LazyVstack and each row item in the LazyVstack is a LazyHstack of horizontally scrollable list of images with some description with line limit of 3 and width of every item is fixed to 100 but height of every item is variable as per description text content. But in any of the rows if the first item has image description of 1 line and the remaining items in the same row has image description of 3 lines then the LazyHStack is truncating all the image descriptions in the same row to one line making all the items in that row of same height. Why LazyHStack is not supporting items of varying height ? Expected behaviour should be that height of every LazyHStack should automatically adjust as per item content height. But it seems SwiftUI is not supporting LazyHstack with items of varying height. Will SwiftUI ever support this feature?
