We are in the midst of testing camera and photo/video access using iPadPro 17 Beta (21A5326a) from within our application, and we are encountering an error message on only one device (iPad Pro 12.9-inch, A2229). Full access to the camera roll has been explicitly granted to the application when prompted. On only the above device, attempting to select an existing photo results in this error popup: "Photo or Video Unavailable: This app is using the Photos picker in an unsupported configuration." (We are able to take and save new photos from within our application on this device with no issues.) I have a second device on hand (iPadPro 10.5-inch, A1701) that presently also has the same iPadOS version installed and is running the same application, and we are able to select existing photos and take new photos with no errors. I have compared the Photos settings on both devices, and they appear to be identical. On a third iPad device running with the same iPadOS version, application, and Photos settings (that device is not in my possession), it has been reported that no errors are encountered when either taking new photos or selecting existing photos via the Photo Picker from within our app. We are trying to figure out what might be causing this error to appear when selecting existing photos on only the A2229 device, and/or what aspect of the configuration or settings would need to be modified in order to use the photo picker on that one iPad Pro. This issue had not been encountered on the A229 device while running with iPadOS 16. Searching the text of this error message online has not returned anything significantly meaningful thus far.

Hello all! I have an app (Scriptio Medication Management) that uses NFC on iPhone, and that works really well. However, I need a larger screen to satisfy customer requests (reports, etc). Because we use NFC tags to authenticate & authorize I need to stick with this tech. I cannot assume that all my customers have iPhone (we also deploy to Android) so pairing an iPad with an iPhone doesn't work for us. I was looking at an external device such as FlowJack, but since iPad no longer has an audio port, this won't work for me. Has anyone been able to solve this type of issue? Ideally I can find a solution that non-technical folks can attach/pair with an iPad to read NFC devices (NOT payment processing). Thanks in advance

Hi, Im Unity Developer and using Apple ARkit XR Plugin package for my project development. I want to access ARkit rgbimage frame and convert to texture2D in my project. It seems that ARkit overrides camera authorization both back and front, so grabbing wecamtexture using another API(e.g. unitywebcamtexture class) does not allowed. Also ARKit does not provide official root to directly get frame from AR camera. Is ther anyone resolved this issue? Thank you.

We were still unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue. While we appreciate that your app is intended primarily for use on iPhone, in order to bring your app into compliance with App Store guidelines, all apps designed for use on iPhone must still be formatted correctly and behave properly when run on iPad. Review device details: Device type: iPad OS version: iOS 17.2 crashlog-82A3D8C6-0136-4C68-A006-6A4AE49B1D1C.txt crashlog-DBA3D1B0-5760-4B47-8FE7-DE44C570271A.txt crashlog-C30814D5-13BC-40FE-92EC-89E736FA7F1B.txt my app crashed only on iPad mini 6th generation its run fine on all other iPad's

I frequently use the Universal Control feature from my Mac, the 27in, to my iPad Pro 5th gen, and recently, when I take a screenshot from my Mac and drag and drop to my tablet, the image won't appear. To be clear, I see the mouse going from the Mac to the iPad, and I see the image floating on the iPad, but when I release the image, it does not appear on the screen. I have the latest update, the Sonoma 14.4. I've searched everywhere and I honestly don't know what to do. I am not good with tech, but I don't know what else to do. In addition, I don't know if this is relevant, but my Mac does not find my iPad on Bluetooth and I have tried everything as well. I restarted it, and everything and nothing.

I'm encountering a crash in my iPad application when using Split View or Slide Over multitasking mode. The crash is occurring with the error message: Crashing on exception: child view controller:<UIPageViewController: 0x155f84200> should have parent view controller:<MyApp.HomeViewController: 0x29e040800> but actual parent is:<MyAoo.HomeViewController: 0x12d2c5e00> The issue seems to be related to incorrect parent view controller assignments when retrieving the top view controller using the window. I've tried to address this by saving the persistent identifier in UserDefaults and comparing it when retrieving the key window, but the problem persists. Here's a snippet of the code I'm using to retrieve the key window: `static func getKeyWindow(for role: UISceneSession.Role = .windowApplication) -> UIWindow? { for scene in shared.connectedScenes { guard scene.session.role == role else { continue } if let savedIdentifier = UserDefaults.standard.string(forKey: "\(scene.session.persistentIdentifier)") { debugPrint("#### saved identifier is \(savedIdentifier)") if scene.session.persistentIdentifier == savedIdentifier { return (scene as? UIWindowScene)?.windows.first { $0.isKeyWindow } } else { debugPrint("#### didn't match identifier") } } else { return (scene as? UIWindowScene)?.windows.first { $0.isKeyWindow } } } return nil }` It seems like the issue arises when the app is opened in a split view, as the persistent identifier changes but the app fails to differentiate between the different instances. Consequently, it takes the wrong Split View window and returns the wrong HomeViewController instance, leading to the crash. How can I properly handle the retrieval of the top view controller to avoid this crash in multitasking mode on iPad? Any insights or suggestions would be greatly appreciated. Thanks in advance!

Is apple still deciding what we can view, disabling parallax on websites (safari) or is there a workaround? I am a graphic designer and web developer with an iPad Pro. iPadPro uses "desktop" css not tablet (due to its larger size), so it looks like the desktop website but the beautiful features of parallax are missing. Not helpful with troubleshooting and editing websites on iPadPro after hours. Anyone know a way to force parallax to work?

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?

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

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? The traces: 0 AGXMetalA12 AGX::BlitContext<AGX::G11::Encoders, AGX::G11::Classes, AGX::G11::ObjClasses>::copyTextureToBuffer(IOGPUMetalResource const*, unsigned long, unsigned long, unsigned long, AGXA12FamilyTexture*, unsigned int, unsigned int, MTLOrigin, MTLSize, unsigned long) + 96 9 PencilKit PKDrawing.image(from:scale:) + 28 0 AGXMetalA13 <redacted> + 96 9 PencilKit PKDrawing.image(from:scale:) + 28 0 AGXMetalA10 <redacted> + 72 9 PencilKit $s9PencilKit9PKDrawingV5image4from5scaleSo7UIImageCSo6CGRectV_12CoreGraphics7CGFloatVtF + 24

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.

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.
