macOS: Sequoia Xcode: 16.1 I am working on a macOS app and it has a widget feature. When I use Swift 6 (Build Settings > Swift Language Version) in IntentExtension, the intent configuration won't show up in macOS Sequoia. If I downgrade to Swift 5, it works without any other changes. Is it a bug or am I missing something? How can I use Swift 6 with IntentExtension.

We recently converted an existing app to adopt scenes (for CarPlay). The app has one main view controller that presents a WKWebView to show our content. Everything works fine in both landscape and portait mode when swiping on the screen to scroll. But with an iPad using an external Magic Keyboard, once you rotate to landscape mode the scrolling gestures are reversed. Swiping vertically on the trackpad is scrolling the page horizontally and vice versa. When this happens an error like below is logged (this error also shows up when in portait mode, but scrolling works as expected): Unexpected window orientation: <UIWindow: 0x10370d8f0; orientation: landscapeLeft (4)> { hidden = NO; frame = {{0, 0}, {1180, 820}}; bounds = {{0, 0}, {1180, 820}}; ownsOrientation = NO; ownsOrientationTransform = NO; autorotationDisabled = NO; windowInterfaceOrientation = unknown (0); rootTransformOrientation = landscapeLeft (4); viewTransformOrientation = unknown (0); autorotationDisabled = NO; orientationVC = ... { providedSupportedOrientations = ( Pu Ll Lr Pd ); resolvedSupportedOrientations = ( Pu Ll Lr Pd ); canPreferOrientation = NO; }; }, event type: 6 It seems to suggest that while the view controller orientation is set correctly. It doesn't know what the orientation is for the window. I have been unable to figure out what would change with adopting scenes that would explain this behavior. I assume it has to do with the potential multi-window nature of it but haven't found any docs that describe how to ensure the window is setup to use the same orientation as the device. Any suggestions on things to check?

I'll describe my crash with an example, looking for some insights into the reason why this is happening. @objc public protocol LauncherContainer { var launcher: Launcher { get } } @objc public protocol Launcher: UIViewControllerTransitioningDelegate { func initiateLaunch(url: URL, launchingHotInstance: Bool) } @objc final class LauncherContainer: NSObject, LauncherContainer, TabsContentCellTapHandler { ... init( ... ) { ... super.init() } ... // // ContentCellTapHandler // public func tabContentCellItemDidTap( tabId: String ) { ... launcher.initiateNewTabNavigation( tabId: tabId // Crash happens here ) } public class Launcher: NSObject, Launcher, FooterPillTapHandler { public func initiateNewTabNavigation(tabId: String) { ... } } public protocol TabsContentCellTapHandler: NSObject { func tabContentCellItemDidTap( tabId: String, }

Does that mean tabId passed to tabContentCellItemDidTap is a String but the one passed to initiateNewTabNavigation is NSString? TabId is UUID().uuidString if that helps. Wondering if UUID().uuidString has something to do with this. Thanks a ton for helping. Please find attached screenshot of the stack trace.

When developing with SwiftUI, I encountered the following error: failed to produce diagnostic for expression; please submit a bug report (https://swift.org/contributing/#reporting-bugs) Since I don’t understand the reason behind this error, what details should I include in the report?

we are migrating our app to support Arabic language support but the requirement is we want the calendar/date object to display as missed. That is all the numbers in english digits and rest all the words like days, months should be in Arabic. I tried few options but at the end its resulting everything is in Arabic or in English but not the mixed as expected. Attaching the expected behavior.

I use the iTunes Library framework in one of my apps, starting with macOS Sequoia 15.1 i can't create the ITLibrary object anymore with the following error: Connection to amplibraryd was interrupted. clientName:iTunesLibrary(ITLibraryLoader) Error connecting to the server via proxy object Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.amp.library.framework" UserInfo={NSDebugDescription=connection to service named com.apple.amp.library.framework} configure failed: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.amp.library.framework" UserInfo={NSDebugDescription=connection to service named com.apple.amp.library.framework} I created a new sandboxed macOS app, added the music folder read permission and it reproduced the error: import SwiftUI import iTunesLibrary @main struct ITLibraryLoaderApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { var body: some View { Button("Load ITLibrary") { loadLibrary() } } func loadLibrary() { do { let _ = try ITLibrary(apiVersion: "1.0", options: .none) } catch { print(error) } } } I restarted my developer machine and the music app with no luck.

Is it possible to use CloudKit and add integrations, Google Drive for example. If possible, how?

I am using a Mac Catalyst with SwiftUI for our document-based app with DocumentGroup. The issue is that when we create a new document or open an existing one, the opened view is completely blank. It is only blank/empty when the "Optimzie for Mac" is checked. If it is "Scaled t oMatch iPad", then it works well. Xcode 16.1 macOS 15.1 struct DocumentGroupTestApp: App { var body: some Scene { DocumentGroup(newDocument: WritingAppDocument()) { file in TestView() // it is empty when it gets opened. It does not work if the option "Optimize for Mac" is checked. If it is scale iPad, then it works. } } } struct TestView: View { var body: some View { Text("Hello, World!") } }

Hello, Team. We used WKWebView for our project. We loaded the HTML file into the webview and added the following configuration. weak var webView: WKWebView! func configWebView() { let webViewConfig = WKWebViewConfiguration() let controller = WKUserContentController() controller.add(self, name: "sometest") webViewConfig.userContentController = controller webViewConfig.processPool = WKProcessPool() webViewConfig.setValue(true, forKey: "allowUniversalAccessFromFileURLs") webViewConfig.mediaTypesRequiringUserActionForPlayback = [] let webpagePreferences = WKWebpagePreferences() webpagePreferences.allowsContentJavaScript = true webViewConfig.defaultWebpagePreferences = webpagePreferences webViewConfig.websiteDataStore = WKWebsiteDataStore.default() webView = WKWebView(frame: .zero, configuration: webViewConfig) webView.navigationDelegate = self webView.uiDelegate = self webView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(webView) NSLayoutConstraint.activate([ webView.topAnchor.constraint(equalTo: view.topAnchor), webView.bottomAnchor.constraint(equalTo: view.bottomAnchor), webView.leadingAnchor.constraint(equalTo: view.leadingAnchor), webView.trailingAnchor.constraint(equalTo: view.trailingAnchor) ]) loadWebView() } func loadWebView() { guard let documentsDirectoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first else { return } let contentFolderURL = documentsDirectoryURL.appendingPathComponent("content") let assetFolderURL = contentFolderURL.appendingPathComponent(interactiveGUID) if FileManager.default.fileExists(atPath: assetFolderURL.path) { let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first! let documentsURL = URL(fileURLWithPath: documentsPath) let fileToLoadPath = (documentsPath as NSString).appendingPathComponent("content/index_p.html") let fileURL = URL(fileURLWithPath: fileToLoadPath) autoreleasepool { DispatchQueue.main.async { [weak self] in guard let self = self else { return } self.webView.loadFileURL(fileURL, allowingReadAccessTo: documentsURL) } } } We are experiencing webview crashes when loading an HTML file. What happened when I loaded the video file? It automatically looped. Webview frequently crashes when the HTM/JS file is loaded. When a webview crashes, the delegate method usually calls webViewWebContentProcessDidTerminate. This method calls webview.reload(). Also we are clear and cache/ deallocate eveything when i initialized those configuration mentioned as the above. Can you suggest a solution to this? Why is webview crashing? Thank you.

Hello! Is there any way to detect when the animation appearing in iOS 18 on switching tab items completes? This applies to TabView in SwiftUI.

I am working in Carrier app i want to check sim change event in my iOS app. please guide me how i can get sim change event. Thanks

I am using swiftui lately in my iOS mobile app, The Mobile app already has a pipeline that detect any experimental features and throw an error I am using swift 5 and as you all know SwiftUI is using some of OpaqueTypeErasure utility types like "some" I heard that in swift 6 the OpaqueTypeErasure is not experimental anymore But upgrading the app swift version will be a very long process Also changing the pipeline will be a very long and tiring process So i want to know if there is a way to remove OpaqueTypeErasure from SwiftUI and what is the alternatives for bypassing the error that being thrown from the pipeline

Hello, My code calls a macOS system library which returns Foundation Date properties. I have a program that will run every night, and output the data via the Swift JSONEncoder and uses DateEncodingStrategy.iso8601. As you likely know, a DST shift happened over the weekend here in the US. In my output, every single Date changed by 1 hour, despite the fact that nothing in the underlying data changed overnight. Here is an example diff in the output. I see the "Z", which I think should not be affected by DST changes. - "dateAdded" : "2003-12-15T17:02:56Z", - "dateModified" : "2007-03-07T04:31:16Z", + "dateAdded" : "2003-12-15T18:02:56Z", + "dateModified" : "2007-03-07T05:31:16Z", Here is a sample of the data: public struct Track: Codable, Hashable { var dateAdded: Date? var dateModified: Date? } And the encoding is here: extension Array where Element == Track { public func jsonData() throws -> Data { let encoder = JSONEncoder() encoder.outputFormatting = [.prettyPrinted, .sortedKeys] encoder.dateEncodingStrategy = .iso8601 return try encoder.encode(self) } } Pretty basic stuff overall. So my questions are: Am I correct in my assumption that .iso8601 is UTC, and that UTC is daylight savings shift agnostic? Is this the right way to ensure the my JSON is encoded in UTC? If the library I am calling is building its Date incorrectly, how may I work around the problem? I'm not reporting the library name right now, in order to ensure that my code is doing the right thing without assumptions. Thanks for any tips!

I'm still discovering swift and the various frameworks. So I'm now trying to create scrolling composition with a grid - containing images - and an NSStackView at on top. However, I'm running into a problem that might seem stupid, but when I try to wrap my NSCollectionView in another NSView and pointing the scrollView.documentView to, I can't scroll anymore... Even though it works fine when I set the scrollView.documentView to the NSCollectionView directly. Working case: override func viewDidLoad() { super.viewDidLoad() scrollView = NSScrollView(frame: .zero) scrollView.hasVerticalScroller = true scrollView.hasHorizontalScroller = false scrollView.scrollerStyle = .overlay scrollView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(scrollView) vStack = NSStackView(frame: .zero) vStack.orientation = .vertical vStack.spacing = 12 * 2 vStack.translatesAutoresizingMaskIntoConstraints = false let hStack = NSStackView() hStack.orientation = .horizontal hStack.spacing = 12 hStack.translatesAutoresizingMaskIntoConstraints = false let label1 = NSTextField(labelWithString: "Collection") hStack.addArrangedSubview(label1) let layout = PinterestLayout() layout.delegate = self collectionView = NSCollectionView(frame: .zero) collectionView.collectionViewLayout = layout collectionView.dataSource = self collectionView.delegate = self collectionView .register( ArtCardCell.self, forItemWithIdentifier: NSUserInterfaceItemIdentifier("ArtCardCell") ) collectionView.backgroundColors = [.BG] collectionView.translatesAutoresizingMaskIntoConstraints = false // vStack.addArrangedSubview(hStack) // vStack.addArrangedSubview(collectionView) scrollView.documentView = collectionView NSLayoutConstraint.activate([ scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor), scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor), scrollView.topAnchor.constraint(equalTo: view.topAnchor), scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor), // vStack.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor), // vStack.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor), // vStack.topAnchor.constraint(equalTo: scrollView.topAnchor), // vStack.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor), // vStack.widthAnchor.constraint(equalTo: scrollView.widthAnchor), collectionView.widthAnchor.constraint(equalTo: scrollView.widthAnchor), // vStack.arrangedSubviews[0].leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 12), // vStack.arrangedSubviews[0].trailingAnchor.constraint(equalTo: scrollView.trailingAnchor, constant: -12), // vStack.arrangedSubviews[0].topAnchor.constraint(equalTo: scrollView.topAnchor, constant: 80) ]) collectionView.postsBoundsChangedNotifications = true NotificationCenter.default.addObserver(self, selector: #selector(didScroll(_:)), name: NSView.boundsDidChangeNotification, object: collectionView.enclosingScrollView?.contentView ) } collectionView height: 3549.0 ScrollView height: 628.0 StackView height: -- Dysfunctional case: override func viewDidLoad() { super.viewDidLoad() scrollView = NSScrollView(frame: .zero) scrollView.hasVerticalScroller = true scrollView.hasHorizontalScroller = false scrollView.scrollerStyle = .overlay scrollView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(scrollView) vStack = NSStackView(frame: .zero) vStack.orientation = .vertical vStack.spacing = 12 * 2 vStack.translatesAutoresizingMaskIntoConstraints = false let hStack = NSStackView() hStack.orientation = .horizontal hStack.spacing = 12 hStack.translatesAutoresizingMaskIntoConstraints = false let label1 = NSTextField(labelWithString: "Collection") hStack.addArrangedSubview(label1) let layout = PinterestLayout() layout.delegate = self collectionView = NSCollectionView(frame: .zero) collectionView.collectionViewLayout = layout collectionView.dataSource = self collectionView.delegate = self collectionView .register( ArtCardCell.self, forItemWithIdentifier: NSUserInterfaceItemIdentifier("ArtCardCell") ) collectionView.backgroundColors = [.BG] collectionView.translatesAutoresizingMaskIntoConstraints = false vStack.addArrangedSubview(hStack) vStack.addArrangedSubview(collectionView) scrollView.documentView = vStack NSLayoutConstraint.activate([ scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor), scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor), scrollView.topAnchor.constraint(equalTo: view.topAnchor), scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor), vStack.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor), vStack.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor), vStack.topAnchor.constraint(equalTo: scrollView.topAnchor), vStack.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor), vStack.widthAnchor.constraint(equalTo: scrollView.widthAnchor), collectionView.widthAnchor.constraint(equalTo: scrollView.widthAnchor), vStack.arrangedSubviews[0].leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 12), vStack.arrangedSubviews[0].trailingAnchor.constraint(equalTo: scrollView.trailingAnchor, constant: -12), vStack.arrangedSubviews[0].topAnchor.constraint(equalTo: scrollView.topAnchor, constant: 80) ]) } collectionView height: 508.0 ScrollView height: 628.0 StackView height: 628.0

I have a stackview which have 2 labels class TextView: UIView { @IBOutlet private weak var stackView: UIStackView! { didSet { stackView.isAccessibilityElement = true stackView.accessibilityLabel = label1.text + label2.text } } @IBOutlet private weak var label1: UILabel! { didSet { label1.accessibilityIdentifier = "label1" } } @IBOutlet private weak var: UILabel!{ didSet { label2.accessibilityIdentifier = "label2" } } } My goal here is to have a combines accessibility label for the stackview and yet able to access the accessibilityIdentifier of child elements for automation.

I would like to see examples of how to do this. Apple states that explicit clang modules don't work with C++ interop. ObjC++ has simple interop with C++. Swift does not. And so I'd like to know how to setup my C++ projects to build them as clang modules.

I want to expose few elements for accessibility alone and other for automation alone. But I can only accessibility elements in Accessibility Inspector but can't see Automation Elements self.view.accessibilityElements = [loginButton as Any, registerButton as Any, closeButton as Any] self.view.automationElements = [claimLabel as Any, loginButton as Any, registerButton as Any, intoductionImage as Any, closeButton as Any])
