Still no hypervisor support in iPadOS 17 Hypervisor is indeed physically possible on any of the M series chips included in the iPad Airs and iPad Pros, but locked away the iPadOS. Block hypervisor on iOS is reasonable to me, because it consume powers, not frendly for battery and not sutable for a mobile phone. But for iPadOS, the limitation is not reasonable to me. First, the Guideline 2.5.2 of iOS and iPadOS blocks code execution that loads dynamically, it may protect users because apps may load malicious code after it passes the revew from app store. But if we load codes in the hypervisor, any malicious can only run in the VM, and the safety of the VM is not an issue. Escape from a VM is even harder than escape from the sandbox of the safari browser. Even there are still other concerns about load arbitrary codes to hypervisor, we can limit it only load user selected code to the hypervisor, blocks app load code from interent without user intention. Running user selected code in the hypervisor won't threaten the security at all, there is no reason for Guideline 2.5.2 applies to hypervisor. Second, iPad a laptop replacement in the advertisement. As a laptop, it can't execute any user generated code on it, it can only be interpreted. As a software develper, it means iPadOS basically not useable. I can only run code on a remote server, and use iPad as a thin client. It can't be a standalone devices, even it has a powerful M2 chip. For the xcode on iPad, if apple concerns xcode on iPad breaks the security model, we can run the compiled code in the hypervisor, which isolates the reviewed code and user generated code. iPad has a powerful M2 chip, but iPadOS limit the power for it.

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 currently using a WKWebView to load certain types of documents via loadRequest, but I've recently been running into an issue with .doc files doing this: static NSString *customScheme = @"customscheme"; @interface WordDocWKSchemeHandler : NSObject <WKURLSchemeHandler> @end @implementation WordDocWKSchemeHandler { NSData *_data; NSString *_mimeType; } - (instancetype)initWithData:(NSData*)data mimeType:(NSString*)mimeType{ self = [super init]; if (self) { _data = data; _mimeType = mimeType; } return self; } - (void)webView:(WKWebView *)webView startURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask { NSURL *url = urlSchemeTask.request.URL; if (![url.scheme isEqualToString:customScheme]){ return; } NSURLResponse *response = [[NSURLResponse alloc] initWithURL:url MIMEType:_mimeType expectedContentLength:_data.length textEncodingName:@""]; [urlSchemeTask didReceiveResponse:response]; [urlSchemeTask didReceiveData:_data]; [urlSchemeTask didFinish]; } - (void)webView:(WKWebView *)webView stopURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask{ //empty } @end - (void)_setupWebViewPropertiesAndConstraints{ _webView.navigationDelegate = self; _webView.hidden = YES; [self.view addConstrainedSubview:_webView]; [self.view addConstraints:[_webView constraintsForFillingSuperview]]; self.container.showsLoadingIndicator = YES; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; WKWebViewConfiguration *docConfig = [WKWebViewConfiguration new]; WordDocWKSchemeHandler *schemeHanlder = [[WordDocWKSchemeHandler alloc] initWithData:_content.data mimeType:_content.contentType]; [docConfig setURLSchemeHandler:schemeHanlder forURLScheme:customScheme]; //Setup webview with custom config handler _webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:docConfig]; [self _setupWebViewPropertiesAndConstraints]; NSURL *customURL = [NSURL URLWithString:[NSString stringWithFormat:@"\%@:/",customScheme]]; [_webView loadRequest:[NSURLRequest requestWithURL:customURL]]; } The mimeType is correctly being resolved to "application/msword" but any time we try to load this the navigation fails: -(void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error { The error message here is OfficeImportErrorDomain Code=912. I've tried this on both a simulator and actual device on iOS 17 and 16 and this always fails. I've also tried turning the data into a base64 string and loading it that way and this also fails. Any advice here would be appreciated. It seems like this used to work at some point but no longer works.

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?

Hi! I'm moving my UINavigationBar and UINavigationItem to the iOS 16 style and having trouble with disabling buttons. Before: I'm defining rightBarButtonItems with a few barButtonItems plus a (custom) menuButtonItem (which has a menu with some more actions). After: I'm defining trailingItemGroups and let the system create an overflow menu dynamically, depending on space. I'm also defining some additionalOverflowItems. Here's the problem: How can I access the button/barButtonItem that is showing the overflow menu and call isEnabled = false? My UI, so far, has disabled all buttons during edit mode. I don't want to hide them, but have them grayed out, including the overflow menu button. class MyVC : UIViewController { // ... override func setEditing(_ editing: Bool, animated: Bool) {         super.setEditing(editing, animated: animated) // ... // This doesn't disable the overflow menu button         navigationItem .trailingItemGroups .forEach { $0.barButtonItems .forEach { $0.isEnabled = !isEditing } }     } }

while trying to use the external camera, ios is not detecting exposure setting of connected external camera and check isExposureModeSupported is always returning false. And capture image also don't have any exposure details. How can we use or change these settings

When a user updates their device to iOS 17 (any version) on a device with MDM, our app crashes but only on some device, not all. The same app runs fine on iOS 16. We cannot recreate the issue in-house and even our customers cannot reliably recreate the crash as it only happens on some devices and not others. The crash we get is: SIGABRT: UICollectionView internal inconsistency: missing final attributes for cell Once the device gets this crash, the only way to fix it is to delete and reinstall the app and then everything works fine. Anyone having a similar issue with iOS 17 and MDM?

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?

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, in an App I maintain we have a huge crash count at launch on the iPad. While I can't reproduce it, looking at the stack trace it seems [UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone evaluates to true under some conditions on iPadOS 15. (the crash occurs in an UIViewController that is allocated only on the iPhone in one code location) Is there anything that can cause [UIDevice currentDevice] to return nil, e.g. blocking the main thread? Thanks!

Greetings all, I have a crash report but I cannot figure out what is causing the crash. When I do a debug build on simulator, it is all good. When I make a release build and install on device, it crashes as soon as the mobile app opens. I am using React Native 0.73.2 if that helps at all. Any help understading this crash report is appreciated. Flex-2024-01-31-092208.txt

In my application, a textview and attributed text (with different font and color in it). With IOS 15.4 it is working fine without a code, but with IOS 17.2; when I pinch and zoom in, the text comes to left side like a invisible column and zoom in. It's not working properly. But WHY ?... and most inportant... How can I fix it ? Thanks...

hey! i have an ipad pro 11’ 2018, and everything was working fine until one day i wasn’t able to connect my apple pencil 2 to my ipad. the pencil itself gets detected it just won’t connect with my ipad. i already tried restarting, unpairing (even since i wasn’t able to pair it) and even restoring my ipad. does anyone have a solution for this?

I am currently investigating converting a large macOS, iOS, and iPadOS app from using AppKit and UIKit for the front end to using SwiftUI. This app uses a sidebar/source list style window on macOS and iPadOS. The content/detail portion of the window displays hierarchal information so you can drill in for details and back out to get an overview. In this application the selection in the sidebar changes how the information in the content/detail area is displayed but not what information is displayed. The included ContentView SwiftUI code shows an example of this. The sidebar lets you change the background color of the detail view and the content of detail view provides all of the "links" to navigate forward to see more data. To try and make this work I am using a NavigationSplitView with a List for the sidebar and a NavigationStack for the detail. The sidebar list takes a selection binding and the list contents uses tags to map the selection. It does not use NavigationLink and the selection state variable is not used in the NavigationStack of the detail view. With this setup, I would expect there to be no relationship between the sidebar and detail views. The problem is whenever the selection in the list in the sidebar changes the NavigationStack in the details backs up to its root view. I have included an example ContentView showing this behavior. Is there anyway to prevent this? Should I file a "feedback" to request this functionality? Thank you in advance for any help. @State var path: [ContentView.Step] = [] @State var color: Color? = .clear var body: some View { NavigationSplitView { List (selection: $color) { Text ("Clear").tag(Color.clear) Text ("White").tag(Color.white) Text ("Blue").tag(Color.blue) Text ("Green").tag(Color.green) } } detail: { NavigationStack (path: $path) { VStack { NavigationLink(value: ContentView.Step.a) { Text("Push A") } NavigationLink(value: ContentView.Step.b) { Text("Push B") } NavigationLink(value: ContentView.Step.c) { Text("Push C") } Image(systemName: "globe") .imageScale(.large) Text("Hello, world!") } .navigationDestination(for: ContentView.Step.self) { step in step.body .toolbar { ToolbarItemGroup(placement: .automatic) { Button { _ = path.popLast() } label: { Text("Back") } .disabled (path.count <= 0) } } } } .frame(maxWidth: .infinity, maxHeight: .infinity) .background(color) } } enum Step: Hashable { case a case b case c var body: some View { Group { switch self { case .a: VStack { Text ("A") NavigationLink(value: ContentView.Step.b) { Text("Push B") } NavigationLink(value: ContentView.Step.c) { Text("Push C") } Image(systemName: "globe") .imageScale(.large) .hidden() Text("Hello, world!") } case .b: VStack { NavigationLink(value: ContentView.Step.a) { Text("Push A") } Text ("B") NavigationLink(value: ContentView.Step.c) { Text("Push C") } Image(systemName: "globe") .imageScale(.large) Text("Hello, world!") .hidden() } case .c: VStack { NavigationLink(value: ContentView.Step.a) { Text("Push A") } NavigationLink(value: ContentView.Step.b) { Text("Push B") } Text ("C") Image(systemName: "globe") .imageScale(.large) .hidden() Text("Hello, world!") .hidden() } } } } } }

Hi, I'm using Whirlyglobe on iPad and iPhone and it worked fine so far until now. I upgraded to Xcode15, and now I have issues displaying the globe on my iPad. iPhone works without issues, but iPad throws the following error and doesn't display the globe anymore: "Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (00000004:kIOGPUCommandBufferCallbackErrorSubmissionsIgnored)" When I deploy with Xcode14.3.1, everything works fine. All systems MacOS and iPadOS, and iOS are updated to the latest versions, and I'm using MBP Max M1 any idea how to solve the issue? I guess it has to do with Metal... ?! thanks in advance, M.

Hi, We have an app that is built for adhoc distribution and the devices that the app is installed on does not have internet connection while in use. From time to time, after the app has been in use for a while, the error message "Unable to Verify App: An internet connection is required to verify the trust of the developer' ... This app will not be available until verified." will randomly pop up and cause the app to be not usable. Why does this message appear randomly? Is there any way to prevent this error message from appearing as the devices do not have internet connection and the users are not able to verify app and continue using the app.
