I'm working on an app (actually in Test Flight) that has camera and NFC support. So in iPhone is obviously working as expected, but when testers want to try the camera "aspect" of the app on iPads they can't even download the app it says "No compatible hardware" in Test Flight. What I need to do in this case, I already have a UI/UX solution when theres no NFC support or it's disabled (Android can detect this) but here I have no clue if I'm missing something. Thanks in advance

I am in the public beta. On my iPad, it shows that RC for 17.4 is available but can’t be installed because space is low. I have to use Devices or Finder to update. When I connect my iPad to my pc or Mac both say 17.3.1 is the latest version…even though the iPad says RC 17.4 is available. So it won’t update. This just started recently. Any suggestions?

When showing PDF document in UIDocumentInteractionController and when tap on share button > Print, app crash. Below is the crash log *** Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and [UIPrintPanelNavigationController shouldAutorotate] is returning YES' It's a iPad app supporting Landscape orientation only. And its in Objective C.

Hello, I am working on an AR application using the IPad Pro 5th gen and I need to have more informations about the precision of the accelerometer and the gyroscope about this IPad Pro. If anyone has informations about it or know how to get those informations, it will help me a lot !

I’m creating a hybrid app using Swift and Angular. Angular content is loading on top of the Native Swift WkWebView. Starting from iPad 10th generation only in the app initial launch header area become invisible(invisible means header text becomes white). But once I send the app to background and return to foreground header text becomes black and it will show without problem. I would really like to know whether this is a OS problem and if so is there any pro-grammatical solution for this? if anyone can guide me to proper way fix this much a appreciated!!! Environment: ・Device: iPad 10th generation ・OS：iPad OS 17.3.1 ・Native App : Swift 5

According to a post on hackingwithswift.com, this should work on iOS/iPadOS: import SwiftUI struct ContentView: View { @FocusState private var focused: Bool @State private var key = "" var body: some View { Text(key) .focusable() .focused($focused) .onKeyPress { press in key += press.characters return .handled } .onAppear { focused = true } } } It does not work for me using a hardware keyboard on an iPad running the latest iPadOS 17.4 beta but it does work on my Mac.

Hi! Can anyone help me? According to the compatibility list, I am supposed to be able to connect both of my devices ( sidecar), however whenever I use Bluetooth to connect both of them, my iPad displays a message saying that my Macbook is not supported. I've already tried updating both devices to the latest updates, still now working... What am I doing wrong?

Hello, I've been developing a web app which I need the front camera and need to take a picture at a higher resolution. But I have one issue. When I call navigator.mediaDevices.getUserMedia() in the browser to get the resolution of the camera, it shows it as 2052 x 2736. But it's a 12 MP front camera. I take a picture of myself using the camera app on the iPad and it shows 12 MP picture. The back camera reports it fine. You can also test it out on webcamtests.com to see the resolution.

we have corp own devices (ipad's) that need to disable the ability of users to turn off the location services as well as airplane mode and GPS, how this can be done? Thanks in advance

In 2 days we have observed in Crashlytics over 50 crashes related to PKDrawing.image with EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000210 So far all on iPads with A10, A12 and A13; 100% on iOS 17 (17.1.1, 17.2, 17.3) (while in others the percent of iOS 17 was around 60-80%). Context: Images of the varying frame and scale resulting in screen resolution are being generated sequentially (in a background serial queue called almost one after another when requested), updating one CALayer.contents (and only after this update on Main Thread the next generation is allowed). One zoomable PKCanvasView is present on screen. The crashing line in code: let image = drawing.image(from: frame, scale: renderScale).cgImage The questions: Is there anything that can be done apart from throttling generation? Can the circumstances of the crash be determined – are there any indications accessible in code before calling PKDrawing.image that app might crash?

There is an application on iPhone. The Action Extension is used, it works great on the iPhone, but when you add Destination = iPad, the application starts, works, but the extension does not work. Error: -[_EXSinkLoadOperator loadItemForTypeIdentifier:completionHandler:expectedValueClass:options:] nil expectedValueClass allowing {( NSURL, NSDictionary _EXItemProviderSandboxedResource, NSUUID, NSDate, NSArray, NSData, NSString, NSNumber NSError UIImage, NSValue )} The error occurs here: if itemProvider.hasItemConformingToTypeIdentifier(typeImage) { itemProvider.loadItem(forTypeIdentifier: typeImage, options: nil) { item, error in Doesn't work on a real device, works on simulators. iOS 17.2, XCode 15.2. On simulator first time the extension works and opens the main app, but on the second attempt the main app is not called (after selecting the extension, the image is kinda shadowed and then the shadow disappears). On simulator tested with iPad 6, iPad 9, iPad 10, iPad Air 6. On real iPad 6 does not work at all.

I am developing my app for the Swift Student Challenge 2024. I have made significant progress on it and have been building it on a M1 Mac, where it works perfectly. However, when testing it on some iPads (specifically, the iPad Pro 2018 and iPad Air 5 M1), it did not perform well on these devices. I am wondering if I can specify whether the app should be reviewed on a Mac (M1 or later) or if it will be reviewed on an iPad.

Hi everyone, I'm working for an aircraft operator as an engineer. Our pilots use iPads for their operations and different applications on it. One of the application (Jeppesen FliteDeck Pro X) is using a feature that uses the GPS of the iPad (we use iPad 9th Wifi+Cellular). In order to prove that the application is reliable for operations, we need to prove to the Authorities that the GPS of the iPad can receive more than 12 channels from satellites. Does it exist a way to know approximately how many channels an iPad can receive? Or does a statement exist from Apple? We know that it is capable of, but we need to be able to prove it. Your help would be greatly appreciated. Thank you for your support. Paul

If two iOS/iPadOS devices have your app opened, is it possible to have the apps send data to each other over a wired connection? E.g. If two iPhone 15s are connected by USB-C, can I get my app in iPhone A to send data to iPhone B and vice-versa? I've been looking around for quite a while now and at this point I just want to know if it's technically feasible.

I figured out how to use a Mapkit offline in swift and make the map usable offline . Would a project with a Mapkit still be accepted in the contest? Another question! Are essays required this year? I don't see it in the requirements.

Hello, Sometimes I need to send a message via sendMessageToProvider to tell the proxy service in NetworkExtension that it should be restarted It looks like this: self.sendMessageToProvider("restart"...) { resp if resp != "ok" { // stopVPNTunnel()... } } Then accept the request in NetworkExtension, which looks like: open override func handleAppMessage(_ messageData: Data, completionHandler: ((Data?) -> Void)?) { reasserting = true setTunnelNetworkSettings(nil) { error in startTunnel() { reasserting = false completionHandler("ok"...) } } } But NetworkExtension crashes occasionally and I spent a long time looking for the cause but found nothing. Where should I start?

On iOS 16 (16.4 specifically) and not iOS 17, I am running into an issue where navigationPath in MyNavigationViewModel is cleared when my app is backgrounded. I seemingly couldn't find much discussion around this happening. I'm hoping there is a work around and this is not intended, as the larger project I am working on depends on the state of navigationPath persisting despite being backgrounded. Note: Since I am working on a larger project, so I'm trying to mimic it's structure, which is why I am doing things like passing my view model as an environment object, and having a button in the side bar to push the initial view on to the navigation destination. To reproduce and observe the issue using the sample code below: Swipe from the left edge of the screen to open the side bar (not sure why applying the .balanced style is not having the sidebar displace the detail view, but that's a separate issue I'm not concerned about...) Click the button "Present Detail View" Background the app Wait some time (you will be able to see the print statement in the didSet print out a count of 0 for navigationPath) Reopen the app Observe the Base detail view is displayed, as opposed to the view that was pushed by pressing the side bar button. The navigation path was cleared. Any advice on how to deal with this issue? public class MyNavigationViewModel: ObservableObject { @Published var navigationPath: [MyType] = [] { didSet { print("Count: \(self.navigationPath.count)") } } } public struct MyType: Hashable { public var string: String } public struct MyDestination: View { @EnvironmentObject var viewModel: MyNavigationViewModel var text: String let onBackPressed: ()->() let onNextPressed: ()->() public var body: some View { VStack { HStack { Button(action: { self.onBackPressed() }, label: {Text("Back")}) Button(action: { self.onNextPressed() }, label: {Text("Next")}) } Text("String: \(self.text).") } } } @available(iOS 16.0, *) public struct MyNavigationView: View { @EnvironmentObject var viewModel: MyNavigationViewModel public var body: some View { NavigationSplitView( sidebar: { VStack { Button( action: { self.$viewModel.navigationPath.wrappedValue.append(MyType(string: "Hello")) }, label: { Text("Present Detail View") } ) } }, detail: { NavigationStack(path: self.$viewModel.navigationPath) { Group { Text("This is the detail base view.") } .navigationDestination(for: MyType.self) { data in MyDestination ( text: data.string, onBackPressed: { if(self.$viewModel.navigationPath.wrappedValue.count > 0) { self.$viewModel.navigationPath.wrappedValue.removeLast() } }, onNextPressed: { self.$viewModel.navigationPath.wrappedValue.append(MyType(string: "This is the next thing")) } ) } } } ) .navigationSplitViewStyle(.balanced) .environmentObject(self.viewModel) } } @available(iOS 16.0, *) struct ContentView: View { var body: some View { MyNavigationView().environmentObject(MyNavigationViewModel()) } } @available(iOS 16.0, *) struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }
