Environment→ ・Device: iPad 9th generation ・OS：**iOS17.0.3 ・Printer model：EPSON PX-S730 What I want→ I would like to return an error when I submit a printing job, if the printer is not properly connected to the same WIFI as iPad(iOS17). Current issues→ When I run the below code in iOS17, I was able to successfully submit a print job to printer and, printer returns completed(true) as the result. In iOS16 print job return as an error to the same below code. Problem Description→ In iOS 16.6.1 when you know the correct printer access URL and submit a print job without connecting to the same WIFI as the printer, job return as an error.(return to the error code segment in the below code) But after I updated the app to iOS 17.0.3 and run the same job, it's not returning as an error.(it returns to the completed block in the below code segment and completed Boolean value is true. ) When you check the "Print Summary" window in iPad, the status of the print job is Waiting. So I would like to handle this process in the same way like iOS16 in iOS17. I would like to Print Job to return as a error when printer and iPad not connected to same WIFI(error like "cannot connect to the printer") Test code: let printInfo = UIPrintInfo(dictionary: nil) printInfo.jobName = "Print Job" printController.printInfo = printInfo let pdfURL = Bundle.main.url(forResource: "sample", withExtension: "pdf")! printController.printingItem = pdfURL let printer = UIPrinter(url: printerUrl) printController.print(to: printer, completionHandler: { [self] printController, completed, error in if(error != nil){ print("error") }else if completed{ print("completed") }else{ print("cancel") } }) Does anyone knows if it's a bug in iOS17 or am I missing something?

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

Description When you try to open an iOS app using Universal links from another app while the opening app is being updating, Safari will open an error screen(app will not launch). Is this a specification of universal links on iOS? Also is it possible for the Main app to detect that the application trying to open Universal Link is being updating? Devices iPad 9thGen/10thGen

We are building a hybrid iOS app using Angular (web) rendered inside a WKWebView, hosted by a native Swift app. Communication between the Angular UI and native Swift code is done using WKScriptMessageHandler. The app mostly works without issues, but in rare edge cases, we’re seeing crashes on the main thread, and the crash is reported in Firebase Crashlytics. The root cause appears related to CFRelease and WKScriptMessageHandler. Here’s the relevant crash stack: Crashed: com.apple.main-thread 0 CoreFoundation 0xbfac CFRelease + 44 1 CoreFoundation 0xa734 __CFURLDeallocate + 128 2 CoreFoundation 0x730c _CFRelease + 292 3 libobjc.A.dylib 0x4e28 AutoreleasePoolPage::releaseUntil(objc_object**) + 204 4 libobjc.A.dylib 0x4cbc objc_autoreleasePoolPop + 260 5 WebKit 0x99f194 WebKit::WebUserContentControllerProxy::didPostMessage(WTF::ObjectIdentifierGeneric<WebKit::WebPageProxyIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WebKit::FrameInfoData&&, WTF::ObjectIdentifierGeneric<WebKit::ScriptMessageHandlerIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::CompletionHandler<void (std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::String const&)>&&) + 680 6 WebKit 0x1b358 WebKit::WebUserContentControllerProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 392 7 WebKit 0xe86b0 IPC::MessageReceiverMap::dispatchMessage(IPC::Connection&, IPC::Decoder&) + 272 8 WebKit 0x23c0c WebKit::WebProcessProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 44 9 WebKit 0xe3f054 IPC::Connection::dispatchMessage(WTF::UniqueRef<IPC::Decoder>) + 252 10 WebKit 0x332d4 IPC::Connection::dispatchIncomingMessages() + 744 11 JavaScriptCore 0x58a7c WTF::RunLoop::performWork() + 204 12 JavaScriptCore 0x599a4 WTF::RunLoop::performWork(void*) + 36 13 CoreFoundation 0x56328 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 14 CoreFoundation 0x562bc __CFRunLoopDoSource0 + 176 15 CoreFoundation 0x53dc0 __CFRunLoopDoSources0 + 244 16 CoreFoundation 0x52fbc __CFRunLoopRun + 840 17 CoreFoundation 0x52830 CFRunLoopRunSpecific + 588 18 GraphicsServices 0x11c4 GSEventRunModal + 164 19 UIKitCore 0x3d2eb0 -[UIApplication _run] + 816 20 UIKitCore 0x4815b4 UIApplicationMain + 340 21 APP1 0xa2f80 main + 21 (AppDelegate.swift:21) 22 ??? 0x1c234eec8 (シンボルが不足しています) Steps: WebView: WKWebView Message passing: WKScriptMessageHandler → passing data from Angular → Swift WKWebView is long-lived and reused Native is using WKUserContentController.add(_:name:) to register handlers Crashes are intermittent (hard to reproduce), but often follow: Screen sleep/wake Push notification open Angular calling native immediately after resume Questions: Has anyone seen this specific crash pattern involving CFRelease and WKScriptMessageHandler?

We’re building a hybrid iOS app using Angular (web) rendered inside a WKWebView, hosted by a native Swift app. Recently, we encountered a crash related to UIKeyboardStateManager in UIKit when switching between text inputs continuously within an Angular screen. Scenario The screen contains several text input fields. A “Next” button focuses the next input field programmatically. After about 61 continuous input field changes, the app crashes. It seems like this may be related to UIKit’s internal keyboard management while switching focus rapidly inside a WebView. crash stack: Crashed: com.apple.main-thread 0 WebKit 0xfbdad0 <redacted> + 236 1 UIKitCore 0x10b0548 -[UITextInteractionSelectableInputDelegate _moveToStartOfLine:withHistory:] + 96 2 UIKitCore 0xd0fb38 -[UIKBInputDelegateManager _moveToStartOfLine:withHistory:] + 188 3 UIKitCore 0xa16174 __158-[_UIKeyboardStateManager handleMoveCursorToStartOfLine:beforePublicKeyCommands:testOnly:savedHistory:force:canHandleSelectableInputDelegateCommand:keyEvent:]_block_invoke + 52 4 UIKitCore 0xa36ae4 -[_UIKeyboardStateManager performBlockWithTextInputChangesIgnoredForNonMacOS:] + 48 5 UIKitCore 0xa160f0 -[_UIKeyboardStateManager handleMoveCursorToStartOfLine:beforePublicKeyCommands:testOnly:savedHistory:force:canHandleSelectableInputDelegateCommand:keyEvent:] + 440 6 UIKitCore 0xa07010 -[_UIKeyboardStateManager handleKeyCommand:repeatOkay:options:] + 5760 7 UIKitCore 0xa2fb64 -[_UIKeyboardStateManager _handleKeyCommandCommon:options:] + 76 8 UIKitCore 0xa2fb08 -[_UIKeyboardStateManager _handleKeyCommand:] + 20 9 UIKitCore 0xa30684 -[_UIKeyboardStateManager handleKeyEvent:executionContext:] + 2464 10 UIKitCore 0xa2f95c __42-[_UIKeyboardStateManager handleKeyEvent:]_block_invoke + 40 11 UIKitCore 0x4b9460 -[UIKeyboardTaskEntry execute:] + 208 12 UIKitCore 0x4b92f4 -[UIKeyboardTaskQueue continueExecutionOnMainThread] + 356 13 UIKitCore 0x4b8be0 -[UIKeyboardTaskQueue addTask:breadcrumb:] + 120 14 UIKitCore 0x4a9ed0 -[_UIKeyboardStateManager _setupDelegate:delegateSame:hardwareKeyboardStateChanged:endingInputSessionIdentifier:force:delayEndInputSession:] + 3388 15 UIKitCore 0xfa290 -[_UIKeyboardStateManager setDelegate:force:delayEndInputSession:] + 628 16 UIKitCore 0xf617c -[UIKeyboardSceneDelegate _reloadInputViewsForKeyWindowSceneResponder:force:fromBecomeFirstResponder:] + 1140 17 UIKitCore 0xf5c88 -[UIKeyboardSceneDelegate _reloadInputViewsForResponder:force:fromBecomeFirstResponder:] + 88 18 UIKitCore 0x4fe4ac -[UIResponder(UIResponderInputViewAdditions) reloadInputViews] + 84 19 WebKit 0xfbe708 <redacted> + 100 20 WebKit 0xfbf594 <redacted> + 340 21 WebKit 0x8a33d8 <redacted> + 32 22 WebKit 0x8cee04 <redacted> + 144 23 WebKit 0x1c83f0 <redacted> + 22692 24 WebKit 0x73f40 <redacted> + 264 25 WebKit 0x162c7c <redacted> + 40 26 WebKit 0x1623b4 <redacted> + 1608 27 WebKit 0x73298 <redacted> + 268 28 WebKit 0x72e48 <redacted> + 660 29 JavaScriptCore 0xdb00 WTF::RunLoop::performWork() + 524 30 JavaScriptCore 0xd744 WTF::RunLoop::performWork(void*) + 36 31 CoreFoundation 0xf92c __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 32 CoreFoundation 0xf744 __CFRunLoopDoSource0 + 172 33 CoreFoundation 0xf5a0 __CFRunLoopDoSources0 + 232 34 CoreFoundation 0xff20 __CFRunLoopRun + 840 35 CoreFoundation 0x11adc CFRunLoopRunSpecific + 572 36 GraphicsServices 0x1454 GSEventRunModal + 168 37 UIKitCore 0x135274 -[UIApplication _run] + 816 38 UIKitCore 0x100a28 UIApplicationMain + 336 39 APP1 0xa2ed0 main + 21 (AppDelegate.swift:21) 40 ??? 0x1aa889f08 (シンボルが不足しています) From reviewing the crash log, it appears that the crash occurs inside UIKeyboardStateManager while handling keyboard or cursor updates.

I'm trying to handle the error in NEHotspotConfigurationManager connection method.When i try even OS network connect dialog showing with "Cannot connect" response return as "Success". In my flow i'm trying to connect to a private network. First i connect using below code and then set the IP Address,SubNetMask,Router and DNS server address manually to already added Wifi by running below code. I'm doing this manually because as i understand you cannot set the IP Address,SubNetMask,Router and DNS server address using Swift. https://forums.developer.apple.com/forums/thread/96834?page=2 I read the above thread and what i can understand from that is it's a bug in the os method. So does this problem fixed on latest iOS version? or is there a way to handle this problem? Error handler code→ let eapSetting = NEHotspotEAPSettings() eapSetting.username = self.username eapSetting.password = self.password eapSetting.supportedEAPTypes = [NEHotspotEAPSettings.EAPType.EAPPEAP.rawValue as NSNumber] eapSetting.trustedServerNames = ["ABC"] NEHotspotConfigurationManager.shared.removeConfiguration(forSSID: self.ssid) let hotspotConfiguration = NEHotspotConfiguration(ssid: self.ssid, eapSettings: eapSetting) manager.apply(hotspotConfiguration){ (error) in if let error = error { print("Error") return } else { print("Success") return } }

We are developing a hybrid iOS app where Angular content is rendered inside a WKWebView, hosted by a native Swift application. We use the GameController framework to detect whether an external Bluetooth keyboard is connected to an iPad. The following code is executed when the app enters the foreground and also when requested by the web layer: func keyboardStatusHandler(){ let isKeyboardConnected = GCKeyboard.coalesced != nil if(!isKeyboardConnected){ //sent status to Angular } else { //sent status to Angular } } Crash details We are seeing intermittent crashes on iPad with the following stack trace: Crashed: GCDeviceSession.HID 0 libobjc.A.dylib 0x7db8 objc_retain_x8 + 16 1 libsystem_blocks.dylib 0xfb8 void HelperBase<ExtendedInline>::copyCapture<(HelperBase<ExtendedInline>::BlockCaptureKind)3>(unsigned int) + 48 2 libsystem_blocks.dylib 0xbc4 HelperBase<GenericInline>::copyBlock(Block_layout*, Block_layout*) + 108 3 libsystem_blocks.dylib 0xc94 _call_copy_helpers_excp + 60 4 libsystem_blocks.dylib 0xef8 _Block_copy + 412 5 libdispatch.dylib 0x1a70 _dispatch_Block_copy + 32 6 libdispatch.dylib 0x792c dispatch_async + 56 7 libdispatch.dylib 0x792c dispatch_channel_async + 56 8 GameController 0xea6dc -[GCKeyboardInput _handleKeyboardEvent:] + 324 9 GameController 0x22508 __53-[_GCKeyboardEventHIDAdapter initWithSource:service:]_block_invoke + 376 10 GameController 0x11d30 -[_GCHIDEventSubject publishHIDEvent:] + 268 11 GameController 0xb79cc __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_3 + 44 12 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 13 libdispatch.dylib 0x12088 _dispatch_async_and_wait_invoke_and_complete_recurse + 272 14 libdispatch.dylib 0x8448 _dispatch_async_and_wait_f + 108 15 GameController 0xb7984 __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_2 + 132 16 GameController 0xb746c __48-[__GCHIDEventUIKitClient _initWithApplication:]_block_invoke + 256 17 UIKitCore 0x11fd394 __61-[UIEventFetcher _setHIDGameControllerEventObserver:onQueue:]_block_invoke_3 + 40 18 libdispatch.dylib 0x1aac _dispatch_call_block_and_release + 32 19 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 20 libdispatch.dylib 0xa2d0 _dispatch_lane_serial_drain + 740 21 libdispatch.dylib 0xadac _dispatch_lane_invoke + 388 22 libdispatch.dylib 0x151dc _dispatch_root_queue_drain_deferred_wlh + 292 23 libdispatch.dylib 0x14a60 _dispatch_workloop_worker_thread + 540 24 libsystem_pthread.dylib 0xa0c _pthread_wqthread + 292 25 libsystem_pthread.dylib 0xaac start_wqthread + 8 Observed scenarios Crash occurs when the app transitions from background to foreground Crash also occurs when the Angular layer requests keyboard status, triggering the same code path Questions Has anyone encountered crashes related to GCKeyboard.coalesced or GCKeyboardInput like this?

Is there a recommended or safer way to detect external keyboard connection status on iPad (especially when using WKWebView)? Any insights, known platform issues, or suggested workarounds would be greatly appreciated. Thanks!
