Our tvOS app makes use of top shelf Carousel style slides to promote our content. We would like to detect when tvOS transitions between individual top shelf slides, regardless of whether the slide transition is made by a user (via the Siri remote), or by the system idle auto-transition. Has anyone achieved this, maybe there are undocumented system hooks or events we can listen to?

Previously this code would trigger fine on pressesBegan in iOS 17 and earlier versions, but no longer works in iOS 18. How can I start capturing pressesBegan in iOS 18? It seems like UIResponder is just not capturing the keyboard anymore? struct ContentView: View { var body: some View { KeyBoardView() } } //To Use in SwiftUI struct KeyBoardView: UIViewRepresentable{ func makeUIView(context: Context) -> KeyEventView { KeyEventView() } func updateUIView(_ uiView: KeyEventView, context: Context) { } class KeyEventView: UIView { init() { super.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0)) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) { print("test") } } }

Hello, I've created an app that follows the user as they navigate through public transport. I want the camera to follow the user and at the same time I want the camera distance (elevation) to change dynamically depending on speed and other factors. I've tried a first approach using camera keyframes, but I've noticed a lot of crashes when the app comes back to the foreground. .mapCameraKeyframeAnimator(trigger: cameraFrame) { camera in KeyframeTrack(\MapCamera.centerCoordinate) { LinearKeyframe(cameraFrame.center, duration: cameraFrame.duration, timingCurve: cameraFrame.curve) } KeyframeTrack(\MapCamera.distance) { LinearKeyframe(cameraFrame.distance, duration: cameraFrame.duration, timingCurve: cameraFrame.curve) } } Some logs mention wrong center coordinates (nan, nan) but when I print them, it's show me valid coordinates. I've also tried manually setting the camera for each position update, but the result is not smooth. position = .camera( .init(.init( lookingAtCenter: newPosition, fromDistance: cameraElevation, pitch: .zero, heading: .zero) ) ) What's the best way to achieve this?

Not sure exactly what’s going on here. I’ve been building out this little app for the past couple of weeks using Xcode 16 betas, and in a couple of places I have code like this: EditItemView(item: inItem) .toolbar { ToolbarItem { Button(action: { self.printLabel(item: inItem) }) { Label("Print Label", systemImage: "printer.filled.and.paper") } } } Now all of a sudden I'm getting an error on .toolbar: “Trailing closure passed to parameter of type 'Visibility' that does not accept a closure.” Looking at the comment for toolbar, it says this method "specifies the visibility," which is a weird thing for it to do with a name like that. But it also has a deprecation tag that I don't quite understand: @available(macOS, introduced: 13.0, deprecated: 100000.0, renamed: "toolbarVisibility(_:for:)"). The name change makes sense, given the description. But what is the huge deprecation version number? Just a hack? And why is this code no longer compiling? As I'm commenting out instances of this, all my toolbars are failing in this way. ETA: yeah, I finally found the right declaration of .toolbar: func toolbar<Content>(@ViewBuilder content: () -> Content) -> some View where Content : View. It's no longer choosing that one. I hate Swift sometimes. ETA2: I finally whittled it down to it not liking Label for some reason. Replacing that with Image works. But of course, the compiler won't tell me why. ETA3: It's worse than I thought: I tried to make a small test case for a bug, and Label works just fine. Why does my code not?

Hi everyone, I’m wondering about Core Data. When creating a private context using newBackgroundContext(), does it automatically set the parent to the view context, or is it independent? I'd appreciate it if anyone could clarify this for me. Thanks in advance! 😊

I am familiar with providing the main layered app icon for a tvOS project, but I cannot work out how to successfully add support for alternative layered icons in the info.plist and/or asset catalog and/or build settings for a SwiftUI (or Swift) tvOS project. Whenever I check the result of UIApplication.shared.supportsAlternateIcons it returns false I have witnessed other tvOS apps such as Plex successfully switch the app icon, so it must be possible to do. How should the project be configured, what am I missing?

I am trying to change UITabBar background color runtime as theme changed. It is already working in iOS 17 as I am updating UITabBar.appearance().barTintColor and tintColor But for iOS first i need to change because I don't want that new elevated tabbar so I create custom tabbar controller as described in https://stackoverflow.com/questions/78631030/how-to-disable-the-new-uitabbarcontroller-view-style-in-ipados-18 Accepted Answer by awulf. And by doing this, My tabbar looks same like Old and it is working in iPhone and ipad for iOS 16, iOS 17 and iOS 18 too. But the issue is that I am unable to change my tabbar background color. I have also checked this forum: https://forums.developer.apple.com/forums/thread/761056 But not able to change I have set below 3 properties but no effect let appearance = UITabBar.appearance() appearance.backgroundColor = appearance.barTintColor = appearance.tintColor = I have created CustomTabBarController in storyboard and all working fine Also the appearance changed only once per application lifecycle. It will change color by restarting the app then it will pick last selected theme and the colors are changed. but not able to change colors runtime I have also did below code for reloading purpose tabBar.setNeedsLayout() tabBar.setNeedsDisplay() But nothing work

Hi, In this year WWDC 2024 conference a new update to SwiftData allows it to connect to other kind of data sources or databases, at ;east this is what I understood, since then didn't see any tutorial or help document on how to do that for example connecting SwiftData to Firebase if possible ? Kind Regards

So I was trying to use an NSArrayController to bind the contents of a property , first I tried using NSDictionary and it worked great, here's what I did: @interface ViewController : NSViewController @property IBOutlet ArrayController * tableCities; @end ... @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; NSString* filePath = @"/tmp/city_test.jpeg"; NSDictionary *obj = @{@"image": [[NSImage alloc] initByReferencingFile:filePath], @"name": @"NYC", @"filePath": filePath}; NSDictionary *obj2 = @{@"image": [[NSImage alloc] initByReferencingFile:filePath], @"name": @"Chicago", @"filePath": filePath}; NSDictionary *obj3 = @{@"image": [[NSImage alloc] initByReferencingFile:filePath], @"name": @"Little Rock", @"filePath": filePath}; [_tableCities addObjects:@[obj, obj2, obj3]]; } @end Now for an NSPopUpButton, binding the Controller Key to the ArrayController and the ModelKeyPath to "name" works perfectly and the popupbutton will show the cities as I expected. But now, instead of using an NSDictionary I wanted to use a custom class for these cities along with an NSMutableArray which holds the objects of this custom class. I'm having some trouble going about this.

I have a view containing either a TextField or a SecureField. I'm hoping I can use a single FocusState value that will apply to either the TextField or SecureField. (I'm using FocusState to ensure the cursor will be in the field when it initially loads) I've verified this works in a sample project when the view is in a WindowGroup. But when I instead use a DocumentGroup ~50% of the time when the view loads/launches, it does not have focus. Here is my ContentView: struct ContentView: View { let coinFlip: Bool = .random() // used to choose between the TextField and the SecureField @State var fieldContent: String = "" // bound to the Field value @FocusState var focus: Bool var body: some View { VStack { Text("Coin Flip: \(coinFlip)") actualField .focused($focus, equals: true) } .onAppear() { focus = true } } @ViewBuilder var actualField: some View { if coinFlip { TextField("Enter text here", text: $fieldContent) } else { SecureField("Enter secure text here", text: $fieldContent) } } } and here is my App swift file @main struct ModernTurtleApp: App { var body: some Scene { // WindowGroup { // ContentView() // } DocumentGroup(newDocument: ModernTurtleDocument()) { file in ContentView() } } } When this code runs, the Field has focus about 50% of the time on initial launch. When I uncomment the WindowGroup and comment the DocumentGroup, the field always has focus on initial launch. I realize I can work around this behaviour by using an optional enum for FocusState. I would be ok going this route, but I first want to try to understand the behaviour I'm seeing, and possibly keep my simpler FocusState implementation. Thanks, in advance for any help.

I'm using React Native to create a mobile application.When I click on a button in my app, I need to programmatically take a screenshot of the current page of my application together with the iPhone status bar that shows the time, cellular provider, and battery level.

Hi guys, I have a really odd problem. Whenever I try to add a vertical ScrollView, VStack or a LazyVStack to this code everything disappears.

Hi, Are there any macros that can be used with Logger to automatically capture the SwiftUI function that the message originates from? Currently, I am using something similar to: Logger.misc.error("In \(#fileID), \(#function): \(error)") Currently, the #function only tells me that it originates in body... Ideally, I'd like to be able to tell if it was with an onAppear, onChange, Button, alert, etc... I realize I can manually enter this, but was wondering if there was a more automated way to capture this info. Thx,

Hello, Dear Developers Problem Description My team is working on functionality test in iOS18. Basically, application functionality works as expected without any modification. However, We found a small issue in settings application. iOS 17 In iOS17, 3rd party OSS license string in settings application would been displayed if the license button is been clicked. Model: iPhone SE 3 OS Version: 17.6.1 iOS 18 However, in iOS18, nothing but a blank page. Model: iPhone SE 3 OS Version: 18.0.1 Settings.bundle Below are files in settings.bundle. What I've searched Using XCode 16 makes no change Nothing about settings.bundle in iOS 18 release note A similar post: https://forums.developer.apple.com/forums/thread/764519 The solution in the post doesn't solve my problem. If you know the solution, please let me know. Best wishes.

I have an ios application where I have a tab and a container view. Container view changes according to the tab I have selected. Issue I am facing is that that my table view shows all cells properly in older iphones(iphone with home button), while in newer iphones(iphone with home bar), table view doesn't scroll till the end and hides bottom cell. I have tried adding all necessary constraints and content insets, but still it is giving me same issue I have different class for tabBar, tabBar+containerView, and all related view controllers based on tab selected. Please help me find the solution to this. Thanks

I've been having trouble with finding a good way to allow the user to close the keyboard. Naturally, I'd like to use the keyboard toolbar but it's so inconsistent, it's impossible. Sometimes it shows up, other times it doesn't. At the moment, it's not appearing at all no matter where I put it. On the NavigationStack, on the List inside of it, on the TextField. It just doesn't appear. I added a TapGesture to my view to set my FocusState that I'm using for the fields back to nil, however, this stops the Picker I have from working. I tried using SimultaneousGesture with TapGesture, and that didn't work. For example: .simultaneousGesture( TapGesture() .onEnded() { if field != nil { field = nil } } ) With the current setup, each TextField switches to the next TextField in the onSubmit. The last one doesn't, which will close the keyboard, but I want to give people the option to close the keyboard before that. Does anyone have a good way to close the keyboard?
