I have a data object that dynamically changes the UIImage assigned to one of its instance variables, but when showing this image in SwiftUI, it's always black and white. The following sample code shows the difference between the same image, but using first the native constructor Image(systemName:) and then Image(uiImage:). When using AppKit and Image(nsImage:) this issue doesn't happen. import SwiftUI import UIKit struct ContentView: View { @State var object = MyObject() var body: some View { Image(systemName: "exclamationmark.triangle.fill") .symbolRenderingMode(.palette) .foregroundStyle(.white, .yellow) Image(uiImage: object.image) } } class MyObject { var image = UIImage(systemName: "exclamationmark.triangle.fill")! .applyingSymbolConfiguration(.init(paletteColors: [.white, .systemYellow]))! } #Preview { ContentView() }

The App Store Connect API documentation still doesn't list the new 13" iPad display type: https://developer.apple.com/documentation/appstoreconnectapi/screenshotdisplaytype When adding screenshots to 13" iPads on the website, they still seem to use the display type APP_IPAD_PRO_3GEN_129 when listed by the API, and uploading to that same type uploads them to the 13" display type instead, but then there is the requirement that one still has to upload screenshots for 12.9" display type, without an apparent way of doing so. I would expect to have an option to upload to 13" display type that is also used for 12.9" display type. Do we have to wait for Apple to update the documentation or does someone know a workaround?

I'm trying to bind a NSProgressIndicator to Progress, but with the following code I only get an indeterminate progress indicator with a blue bar forever bouncing left and right, even after the two timers fire. According to the documentation: Progress is indeterminate when the value of the totalUnitCount or completedUnitCount is less than zero or if both values are zero. What am I doing wrong? class ViewController: NSViewController { let progress = Progress() override func loadView() { view = NSView(frame: CGRect(x: 0, y: 0, width: 500, height: 500)) let progressIndicator = NSProgressIndicator(frame: CGRect(x: 100, y: 100, width: 100, height: 100)) progressIndicator.bind(.isIndeterminate, to: progress, withKeyPath: "isIndeterminate") progressIndicator.bind(.value, to: progress, withKeyPath: "completedUnitCount") progressIndicator.bind(.maxValue, to: progress, withKeyPath: "totalUnitCount") progressIndicator.startAnimation(nil) view.addSubview(progressIndicator) progress.completedUnitCount = 3 progress.totalUnitCount = 10 Timer.scheduledTimer(withTimeInterval: 1, repeats: false) { _ in print(1) self.progress.completedUnitCount = 6 } Timer.scheduledTimer(withTimeInterval: 6, repeats: false) { _ in print(2) self.progress.completedUnitCount = 0 self.progress.totalUnitCount = 0 } } }

With a Button I can directly copy contents to the clipboard via UIPasteboard.general.setObjects(objects), but this is iOS-specific so I was hoping that ShareLink would allow me to share items in a platform-independent way. Is it possible to show a Copy item in the ShareLink sheet? import SwiftUI struct ContentView: View { let myType = MyType() var body: some View { ShareLink(item: myType, preview: SharePreview(myType.text)) } } class MyType: Transferable { let text = "asdf" static var transferRepresentation: some TransferRepresentation { ProxyRepresentation { myType in return myType.text } } } #Preview { ContentView() }

I'm trying to use @Environment(\.openDocument) private var openDocument but it seems to only be available on macOS. How can I open a document programmatically on iOS? My app has a custom interface for browsing and opening files, so that a tapped file should be shown in the current window, replacing the current file if it exists.

A user of my app, which shows subtitles loaded from a text file above a video loaded from another file, reported that it crashes within minutes of launching it. The user confirmed that the crash only happens when they load a video within the app; if they use it without a video, it doesn't crash. The subtitles are shown in a NSTextView added to AVPlayerView.contentOverlayView. What could cause such a crash? I'm not able to reproduce it. (I tried attaching the full crash report but I always got a validation error "This post contains sensitive language. Please revise it in order to continue.")

In SwiftUI we can use @AppStorage to save app settings. In my app, I have a settings view which allows the user to change various settings. Since there are many of them, it's not practical to declare a binding for each setting between the settings view and whatever other views effectively use that setting. Is there a more convenient way to store a setting in one view and access it in another view?

URLResourecKey.tagNamesKey is only available on macOS, so apparently there's no way of reading or writing file tags on iOS. Why is this the case, given that file tags can be set via Finder on macOS and the Files app on iOS devices? Is there a workaround?

The sample project Filtering Network Traffic uses IPC (NSXPCConnection etc.) to send data from the network extension to the app, but the documentation for NEFilterProvider says The sandbox prevents the Filter Data Provider extension from moving network content outside of its address space by blocking all network access, IPC, and disk write operations. Since my network extension forwards all network traffic to the app so that the user can see it, I was wondering when the app isn’t running and the user shuts down the machine, if the network extension could write the flows it wasn’t able to forward to the app to disk, so that it could read them on the next successful connection to the app. Then almost by accident I read again the documentation and according to the quoted passage a network extension cannot write to disk, but it also cannot use IPC. Is NSXPCConnection not considered IPC, or could the statement that it cannot write to disk be false as well?

XCUIElement has two methods named typeKey(_:modifierFlags:): the first one takes a String as an argument, the second one a XCUIKeyboardKey, which has constants like .downArrow. Now, even if the documentation says that both methods are "Available in macOS and in iPadOS 15 and later", when compiling the UI tests for iOS, the following line app.typeKey(.downArrow, modifierFlags: []) produces a compiler error Type 'String' has no member 'downArrow' Am I missing something or is there a workaround?

I'm using the following code to launch a UI test that forces a specific app language and moves a slider. I noticed that when forcing right to left text direction (for Arabic or Hebrew), during the UI test the slider doesn't move. The app content: struct ContentView: View { @State private var slider = 0.0 var body: some View { Slider(value: $slider, in: 0.0...1.0) } } The UI test: final class problemUITests: XCTestCase { func testExample() throws { let app = XCUIApplication() let locale = Locale(identifier: "ar") app.launchArguments += ["-AppleLanguages", "(ar)", "-AppleLocale", "ar"] if locale.language.characterDirection == .rightToLeft { app.launchArguments += ["-NSForceRightToLeftWritingDirection", "YES", "-AppleTextDirection", "YES"] } app.launch() app.sliders.element.adjust(toNormalizedSliderPosition: 0.3) } } Am I missing something or is there a workaround?

In TextKit 1 we have the method NSTextStorage.addLayoutManager(_:) that allows to show the same text in multiple text views. This method exists with NSLayoutManager but not with NsTextLayoutManager. Is there a way to achieve the same thing with TextKit 2?

All the threads only contain system calls. The crashed thread only contains a single call to my app's code which is main.swift:12. What could cause such a crash? Crash report

Among the newest crash reports downloaded by Xcode for my App Store app there is one that contains a single thread, crashed at libsecinit_appsandbox.c, without any trace of my app name. What could possibly cause such a crash? Is this something related with app signing? The app has been on the App Store for a long time and this never happened to me.
