I am trying to do inline to icon and text in tab bar but it is not allowing me to do it in compact, but it showing me in regular mode , but in regular mode tab bar going at top in portrait mode , But my requirement is tab bar required in bottom with icon and text in inline it showed by horizontally but it showing to me stacked vertically, will you guide me on this so that I can push the build to live users.

Seeing this magical sand table, the unfolding and folding effects are similar to spreading out cards, which is very interesting. But I don't know how to achieve it. I want to see if there are any ways to achieve this effect and give some ideas. May I ask if this effect can be achieved under the existing API

Facing issue of NSUserDefaults data got cleared on update new version from app store. so all data of user got cleared and user have to login again. I was having app in store with version 1.1.3 and then we have uploaded new version to store with version 1.1.4 but when user download app from store their data was cleared from UserDefaults.so this is big issue in update. need to help. is that apple updated any process on update. Question How Apple change version build in device when we update app from app store. is it uninstall old build and install new build ? Or it is install new version on old version ? Should UserDefaults.standard will delete on update ? Updating Provisioning profile from manual to automatically cause issue on UserDefaults.standard Like UserDefaults got cleared and uuid will change ? Do we have anythings that we can identify specific user as uniq user ? What is better solution to store login data into SQLite store or in UserDefaults as model ? Will appreciate for your help. this is very big issue and login again on update will make app user more effect

Hello There, I was trying to do a Button with title left aligned. With the old UIButton, I would have used the title-/contentEdgeInsets to achieve this, but with the new button these values are deprecated and do not work anymore. As far as I understood, with the new button only the spacing between the elements (sub-, title and image) is controllable. I also tried just setting the buttons width to the same width as the label, what would be possible in my case since it should be kind of a "hyperlink-button" which has no background or border. This works so far, but once the user interacts with the button, the title label gets multiline, which is on the one hand not wanted and on the other hand of course does not look left aligned anymore. (Besides the buttons height is fix in my case which leads to clipping of the title) So here again in short: Is there any way to make the title of the new UIButton left aligned inside of the button? Thank you very much in advance.

the bug look like this video： https://www.youtube.com/shorts/qeUbhJAS0Jo

The app provides a simple drawing functionality on a canvas without using a storyboard. After creating drawings in portrait mode, rotating the simulator or the iPad-Device to landscape mode does not update or rescale the existing drawings to fit the newly expanded canvas area. The app can also be launched directly in landscape mode, allowing drawings to be created before rotating the device back to portrait mode. However, the issue persists, with the drawings not adjusting to the new canvas dimensions. The goal is to achieve the same behavior as in the Apple Notes app: when the iPad is rotated, the drawings should adjust to the newly expanded or reduced canvas area. I would appreciate any suggestions or solutions. Sample Projekt [https://github.com/GG88IOS/Test_Drawing_App)

All of a sudden, after iOS 18.4 was released, I am having tons of navigation problems in my app in production. Buttons navigating to empty pages, views seeming to 'freeze', top navigation bar mismatched with the content of the page. It seems that iOS 18.4 broke a critical piece of UIKit + SwiftUI bridging functionality that my project relies on. ** Originally posted in 'Core OS' topic but realized 'UI Frameworks > General' made more sense. My bad. ** My application is written with both UIKit and SwiftUI components. Here is a breakdown of my setup: UIApplicationDelegate > UIWindow > rootViewController of window is a UITabBarController > each tab is a UINavigationController rootViewController of nav controller is a UIHostingController > rootView of the hosting controller is a SwiftUI View In my SwiftUI views, I have been using NavigationLink for horizontal 'push' style navigation in my SwiftUI views. I do not use NavigationView, I only rely on the bridging capabilities of UINavigationController to action on my NavigationLinks. This has never been an issue, until iOS 18.4 was released. Now, when running iOS 18.4, I am having all sorts of unexpected behavior in the UI. I will break down 2 of these use cases here: Use case A: In one of my SwiftUI views, I have a ForEach for which each element's view is a NavigationLink. This is using the NavigationLink(_ destination:,label:) initializer. Navigating forward from here works/looks normal. However, once I try to navigate backward from that destination (tap the 'Back' button in top left), the view goes blank and the navigation bar at the top of the page (which is maintained by the UINavigationController instance) does not change. If I call popToRootViewController on that nav controller, the navigation bar at the top of the page returns to its normal state, but the view is still blank. It is not until after I have called popToRootViewController, and then navigate to a different tab of the UITabBarController and return to the initial tab, does the SwiftuI content view (the one with the ForEach) finally redraw and the view hierarchy is restored. Here is a warning that is logged in the console when I tap the 'Back ' button: Top view controller's view unexpectedly not in window for navigation transition. Skipping layout. nav = <UINavigationController: 0x1110bbe00>, topVC = <TtGC7SwiftUI19UIHostingControllerV5MyApp10MyPage: 0x106814e00> EDIT: If I replace the NavigationLink with a call to UINavigationController.pushViewController, I am still seeing the exact same behavior. Pressing back button makes the view empty > need to pop to root view controller and switch tabs in order to restore the view. Use case B Another instance of this issue happens whenever I try to use a NavigationLink inside of a view that itself was the destination of a NavigationLink in its parent view (i.e.: Root view > detail view > sub-detail view). For example, take the detail view destination in use case A. I have tapped a NavigationLink from the ForEach and landed on the detail view. Again, so far things work/look normal. Now, if I tap on another NavigationLink from that detail view, the view does not transition to the new page. The top navigation bar does transition, and shows the title and actions associated with this second destination. However, the view of this second destination is not displayed. It is worth noting that the same warning I mentioned above is also logged when I tap the NavigationLink to navigate to this second destination. Top view controller's view unexpectedly not in window for navigation transition. Skipping layout. nav = <UINavigationController: 0x109859400>, topVC = <TtGC7SwiftUI19UIHostingControllerVVS_19BridgedPresentation8RootView: 0x300ab8000> Strangely, if I switch to a different tab of the UITabBarController and back to the initial tab, this second destination's view is successfully rendered. It seems that switching tabs in this UITabBarController is calling something in either SwiftUI or UIKit that is redrawing my views. Conclusion This is a serious issue with UIKit + SwiftUI bridging support. I have never had problems like this until devices started running iOS 18.4, and there is nothing in the iOS 18.4 changelog that suggests this was an intentional change. All of a sudden, after updating to the latest iOS version, my app is totally broken. I want to be clear that I'm not using deprecated NavigationLink methods in these instances. My app's minimum deployment target is iOS 16. I know that there are more modern navigation APIs like navigation stack, etc. I am looking for answers about my use case: whether it is officially unsupported as of iOS 18.4, whether this setup should be supported and this is indeed some sort of bug in iOS, or anything in-between. I'm happy to provide formatted code if needed for discussion purposes. This is about my entire app's view hierarchy so there are a lot of disparate lines of code that make up this problem.

iPhone16ProMax 通过[UIScreen mainScreen].bounds.size获取屏幕宽高 使用XCode15获取屏幕宽高为430 * 930 使用XCode16获取屏幕宽高为440 * 956 这是为什么？

Device: iPhone 16 Pro Max System Version: 18.3.1 Screen width and height obtained using [UIScreen mainScreen].bounds.size are as follows Why are the two results different?

I have an iOS app that relies on dynamic text size such that all fonts in the app respect the user's setting of Text Size in the iOS Settings app. This app also runs on macOS via Mac Catalyst. But until macOS 14 Sonoma, there was no Text Size setting in the macOS Settings app. But even as of Sonoma, the Text Size setting isn't usable by 3rd party apps. And Sequoia doesn't seem to change that. As a work around, my Mac Catalyst app provides its own Text Size setting. I was able to make it work by providing my own UIApplication subclass and overriding preferredContentSizeCategory. Under macOS 12 to macOS 14, this workaround works just fine and all fonts in the app created with code such as UIFont.preferredFont(forTextStyle:) gives appropriately sized fonts based on the overridden content size category. However, this workaround stopped working with macOS 15 Sequoia. I've also tried code such as: self.window.traitOverrides.preferredContentSizeCategory = myCustomSizeCategoryValue and self.window.maximumContentSizeCategory = myCustomSizeCategoryValue self.window.minimumContentSizeCategory = myCustomSizeCategoryValue in the scene delegate but that made no difference. Is there any way to get code such as UIFont.preferredFont(forTextStyle:) to return an appropriately sized font based on some app provided content size category in a Mac Catalyst app running under macOS 15? It sure would be nice if Mac Catalyst apps automatically responded to the macOS Text Size setting under Settings -> Accessibility -> Display -> Text Size just like a native iOS app.

I'm trying to switch to UIKit's document lifecycle due to serious bugs with SwiftUI's version. However I'm noticing the template project from Xcode isn't compatible with Swift 6 (I already migrated my app to Swift 6.). To reproduce: File -> New -> Project Select "Document App" under iOS Set "Interface: UIKit" In Build Settings, change Swift Language Version to Swift 6 Run app Tap "Create Document" Observe: crash in _dispatch_assert_queue_fail Does anyone know of a work around other than downgrading to Swift 5?

Hi Everybody, I am actually developing dynamic shortcuts for my app. I have a problem with the class UIApplicationShortcutIcon. When I pass a personalized icon in the parameter icon as a UIApplicationShortcutIcon(templateImageName: "nameOfTheAsset" I always visualize a black dot instead of my Icon. The icon is imported as .SVG file and rendered as a template. Sincerely I do not know what to do to solve this problem since the documentation is little. Hoping somebody can give some tips to solve the problem

Hello, I have a custom 3D object viewer on iOS that lets users spin the model using the touchscreen or a trackpad and supports coasting (momentum spinning). I need to stop the coasting animation as soon as the user touches down, but I can only immediately detect touches on the screen itself - on the trackpad I can't get an immediate notification of the touches. So far I’ve tried: State.began on my UIPanGestureRecognizer. It only fires after a small movement on both touchscreen and trackpad. .possible on the pan gesture; this state never occurs during the gesture cycle. UIApplicationSupportsIndirectInputEvents = YES in Info.plist; it didn’t make touchesBegan fire for indirectPointer touches. Since UITableView (and other UIScrollView subclasses) clearly detect trackpad “touch-down” to cancel scrolling, there must be a way to receive that event. Does anyone know how to catch the initial trackpad contact—before any movement—on an indirect input device? Below is a minimal code snippet demonstrating the issue. On the touchscreen you'll see a message the moment you touch the view, but the trackpad doesn't trigger any messages until your fingers move. Any advice would be greatly appreciated. Thanks in advance, John import UIKit class ViewController: UIViewController { private let debugView = DebugView() override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .white // Fill the screen with our debug view debugView.frame = view.bounds debugView.autoresizingMask = [.flexibleWidth, .flexibleHeight] debugView.backgroundColor = UIColor(white: 0.95, alpha: 1) view.addSubview(debugView) // Attach a pan recognizer that logs its state let panGR = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:))) panGR.allowedScrollTypesMask = .all debugView.addGestureRecognizer(panGR) } @objc private func handlePan(_ gr: UIPanGestureRecognizer) { switch gr.state { case .possible: print("Pan state: possible") case .began: print("Pan state: began") case .changed: print("Pan state: changed – translation = \(gr.translation(in: debugView))") case .ended: print("Pan state: ended – velocity = \(gr.velocity(in: debugView))") case .cancelled: print("Pan state: cancelled") case .failed: print("Pan state: failed") @unknown default: print("Pan state: unknown") } } } class DebugView: UIView { override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { super.touchesBegan(touches, with: event) for t in touches { let typeDesc: String switch t.type { case .direct: typeDesc = "direct (finger)" case .indirectPointer: typeDesc = "indirectPointer (trackpad/mouse)" case .indirect: typeDesc = "indirect (Apple TV remote)" case .pencil: typeDesc = "pencil (Apple Pencil)" @unknown default: typeDesc = "unknown" } print("touchesBegan on DebugView – touch type: \(typeDesc), location: \(t.location(in: self))") } } }

Hello 👋🏽 I am a new iOS developer and I am having a hard time understanding the behavior of the new UIPasteControl to avoid showing the system prompt. Does anyone has any example code I could look at to understand the behavior. Idk how to set the target of the button to the general pasteboard. also I am using objective-c . thanks cristian

I've read in this post that in order to make the configuration of UIButton adjust my custom font's size automatically I need to add implementation to recalculate the font's size inside configurationUpdateHandler. But how would this look like? I also read something about matching the font's text style. But at this point I'm just guessing. Here's the code: let loginButton = UIButton(configuration: config, primaryAction: nil) loginButton.configurationUpdateHandler = { button in guard var config = button.configuration else { return } let traits = button.traitCollection let baseTitleFont = UIFont.customFont(ofSize: 18, weight: .semibold) let baseSubtitleFont = UIFont.customFont(ofSize: 18, weight: .regular) let scaledTitleFont = UIFontMetrics(forTextStyle: .body).scaledFont(for: baseTitleFont, compatibleWith: traits) let scaledSubtitleFont = UIFontMetrics(forTextStyle: .body).scaledFont(for: baseSubtitleFont, compatibleWith: traits) config.titleTextAttributesTransformer = UIConfigurationTextAttributesTransformer { incoming in var outgoing = incoming outgoing.font = scaledTitleFont return outgoing } config.subtitleTextAttributesTransformer = UIConfigurationTextAttributesTransformer { incoming in var outgoing = incoming outgoing.font = baseSubtitleFont return outgoing } button.configuration = config } Thanks in advance!

My app crashed on iOS 18.1 only, here is the crash log: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'BUG IN CLIENT OF UIKIT: <CPTemplateApplicationScene: 0x1114bb780> -[UIScene _registerSettingsDiffActionArray:forKey:]: Registering the scene itself results in a retain cycle.'

Hello! I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation. Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible. customurl://open?hello=test According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs ) any URLs should be passed to: func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -&gt; Bool I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil: func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -&gt; Bool This is the case regardless of if the App is started fresh or was already running in the background. My pInfo entry for the custom URL: &lt;key&gt;CFBundleURLTypes&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;CFBundleTypeRole&lt;/key&gt; &lt;string&gt;Viewer&lt;/string&gt; &lt;key&gt;CFBundleURLName&lt;/key&gt; &lt;string&gt;dev.customurl.project&lt;/string&gt; &lt;key&gt;CFBundleURLSchemes&lt;/key&gt; &lt;array&gt; &lt;string&gt;customurl&lt;/string&gt; &lt;/array&gt; &lt;/dict&gt; &lt;dict/&gt; &lt;/array&gt; TLDR: How can I access the parameters, passed with the URL? Any thoughts on what I am doing wrong?

AVPlayer has 3 visual accessibility issues with videos out of the box: The contrast fails for the current time in the video The contrast fails for the remaining time in the video The hit area is too small for the time slider. The WCAG AA requirement is a minimum hit size of 24 x 24. The height of the hit area of the offending region is 8. Is there a known fix for any of these? This can be reproduced with this code in an app playground: import SwiftUI import AVKit import UIKit struct ContentView: View { private let video = URL(string: "https://server15700.contentdm.oclc.org/dmwebservices/index.php?q=dmGetStreamingFile/p15700coll2/15.mp4/byte/json")! @State private var player: AVPlayer? var body: some View { VStack { VideoPlayerView(player: player) .frame(maxWidth: .infinity, maxHeight: 200) } .task { player = try? await loadPlayer(video: video) } } } private struct VideoPlayerView: UIViewControllerRepresentable { let player: AVPlayer? func makeUIViewController(context: Context) -> AVPlayerViewController { let controller = AVPlayerViewController() controller.player = player controller.modalPresentationStyle = .overFullScreen return controller } func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) { uiViewController.player = player } } private func loadPlayer(video: URL) async throws -> AVPlayer { let videoAsset = AVURLAsset(url: video) let videoPlusSubtitles = AVMutableComposition() try await videoPlusSubtitles.add(videoAsset, withMediaType: .video) try await videoPlusSubtitles.add(videoAsset, withMediaType: .audio) return await AVPlayer(playerItem: AVPlayerItem(asset: videoPlusSubtitles)) } private extension AVMutableComposition { func add(_ asset: AVAsset, withMediaType mediaType: AVMediaType) async throws { let duration = try await asset.load(.duration) try await asset.loadTracks(withMediaType: mediaType).first.map { track in let newTrack = self.addMutableTrack(withMediaType: mediaType, preferredTrackID: kCMPersistentTrackID_Invalid) let range = CMTimeRangeMake(start: .zero, duration: duration) try newTrack?.insertTimeRange(range, of: track, at: .zero) } } }

As of iOS 18, as far as I can tell, it appears there's still no AVPlayer options that allow users to toggle the caption / subtitle track on and off. Does anyone know of a way to do this with AVPlayer or with SwiftUI's VideoPlayer? The following code reproduces this issue. It can be pasted into an app playground. This is a random video and a random vtt file I found on the internet. import SwiftUI import AVKit import UIKit struct ContentView: View { private let video = URL(string: "https://server15700.contentdm.oclc.org/dmwebservices/index.php?q=dmGetStreamingFile/p15700coll2/15.mp4/byte/json")! private let captions = URL(string: "https://gist.githubusercontent.com/samdutton/ca37f3adaf4e23679957b8083e061177/raw/e19399fbccbc069a2af4266e5120ae6bad62699a/sample.vtt")! @State private var player: AVPlayer? var body: some View { VStack { VideoPlayerView(player: player) .frame(maxWidth: .infinity, maxHeight: 200) } .task { // Captions won't work for some reason player = try? await loadPlayer(video: video, captions: captions) } } } private struct VideoPlayerView: UIViewControllerRepresentable { let player: AVPlayer? func makeUIViewController(context: Context) -> AVPlayerViewController { let controller = AVPlayerViewController() controller.player = player controller.modalPresentationStyle = .overFullScreen return controller } func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) { uiViewController.player = player } } private func loadPlayer(video: URL, captions: URL?) async throws -> AVPlayer { let videoAsset = AVURLAsset(url: video) let videoPlusSubtitles = AVMutableComposition() try await videoPlusSubtitles.add(videoAsset, withMediaType: .video) try await videoPlusSubtitles.add(videoAsset, withMediaType: .audio) if let captions { let captionAsset = AVURLAsset(url: captions) // Must add as .text. .closedCaption and .subtitle don't work? try await videoPlusSubtitles.add(captionAsset, withMediaType: .text) } return await AVPlayer(playerItem: AVPlayerItem(asset: videoPlusSubtitles)) } private extension AVMutableComposition { func add(_ asset: AVAsset, withMediaType mediaType: AVMediaType) async throws { let duration = try await asset.load(.duration) try await asset.loadTracks(withMediaType: mediaType).first.map { track in let newTrack = self.addMutableTrack(withMediaType: mediaType, preferredTrackID: kCMPersistentTrackID_Invalid) let range = CMTimeRangeMake(start: .zero, duration: duration) try newTrack?.insertTimeRange(range, of: track, at: .zero) } } }

We are trying to develop an app that will be responsible for managing 5000+ managed iPads through Intune MDM. The user flow is to have a device locked to a single app when a user is not logged in, but to make the device available to other apps once a user is authenticated. We already tried UIAccessibility GuidedAccess Mode and autonomous single app mode but those were not sufficient due to our need to be able to toggle this from the background. When the device may be asleep. So another way we could achieve this functionality would be to control all app access under a launching mechanism. That way we could allow one app to be visible in our MDM configuration and try to access our business app through that using deep links. If this were to work, we would have to be able to hide an app and still make it launchable from the manager. Any ideas? Thanks
