I am publishing app to the AppStore but I am having trouble with export compliance. I have implemented Admob by Google so it is making HTTPS requests. Should I submit self classification report to the US government? I am in Czech Republic.

I am trying to click a button programmatically using JavaScript. It is working in macOS Safari, but it doesn't work in iOS Safari. The document.getElementById("buttonid") returns the button, but when I click it, it doesn't do anything. I've spent a lot of time researching what could be the problem, but I couldn't find any solution. I assume it is somehow blocked on iOS. Here is my code for clicking a button: document.getElementById("buttonid").click(); Does anyone know what could be the problem? Thanks in advance

I have a problem with debuging crash log. I have tried debuging it in Xcode, but it is not pointing to any line of code. I don't know how to debug it. It crashed only on iPad (It crashed to some user in production). I think it is regarding PrintKit on thread 0. Can please someone help me? Thanks in advance Code for displaying PrintController: if UIPrintInteractionController.canPrint(pdfURL) {             let printInfo = UIPrintInfo(dictionary: nil)             printInfo.jobName = pdfURL.lastPathComponent             printInfo.outputType = .general             let printController = UIPrintInteractionController.shared             printController.printInfo = printInfo             printController.showsNumberOfCopies = false             printController.printingItem = pdfURL             printController.present(animated: true, completionHandler: nil)         } Crash log: Incident Identifier: INCIDENT ID Hardware Model: iPad13,2 Process: **APP-NAME** [89317] Path: /private/var/containers/Bundle/Application/**ID**/**APP-NAME**.app/**APP-NAME** Identifier: BUNDLE ID Version: 1.0 (4) AppStoreTools: 13C88a AppVariant: 1:iPad13,2:15 Code Type: ARM-64 (Native) Role: Background Parent Process: launchd [1] Coalition: BUNDLE ID Date/Time: 2022-01-05 09:09:35.5332 +0000 Launch Time: 2022-01-05 07:15:54.2451 +0000 OS Version: iPhone OS 15.1 (19B74) Release Type: User Baseband Version: 3.00.00 Report Version: 104 Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Triggered by Thread: 0 Thread 0 name: Thread 0 Crashed: 0 libsystem_kernel.dylib 0x00000001b97c3558 semaphore_timedwait_trap + 8 1 libdispatch.dylib 0x00000001831ccc6c _dispatch_sema4_timedwait + 64 (lock.c:154) 2 libdispatch.dylib 0x00000001831cd270 _dispatch_semaphore_wait_slow + 76 (semaphore.c:116) 3 PrintKit 0x00000001e4adf548 -[PK_HTTPProxy withProtocolSync:] + 252 (PKBonjour.m:232) 4 PrintKit 0x00000001e4adfa94 pk_proxyConnectHTTP + 572 (PKBonjour.m:264) 5 PrintKit 0x00000001e4af4a34 -[PKPrinter(PKPrinterPrivate) getAttributes:count:] + 240 (PKPrinter.m:2744) 6 PrintKit 0x00000001e4af1004 -[PKPrinter doMedia2:] + 84 (PKPrinter.m:1542) 7 PrintKit 0x00000001e4aee88c -[PKPrinter printInfoSupported] + 1216 (PKPrinter.m:969) 8 UIKitCore 0x000000018687ed04 -[UIPrinterUtilityTableViewController initWithPrinter:] + 588 (UIPrinterUtilityTableViewController.m:230) 9 UIKitCore 0x000000018687254c -[UIPrinterBrowserViewController printerInfoButtonTapped:] + 80 (UIPrinterBrowserViewController.m:578) 10 UIKitCore 0x0000000186871340 -[UIPrinterTableViewCell printerAccessoryViewInfoButtonPressed:] + 84 (UIPrinterBrowserViewController.m:327) 11 UIKitCore 0x000000018687054c -[UIPrinterAccessoryView infoButtonPressed:] + 92 (UIPrinterBrowserViewController.m:124) 12 UIKitCore 0x0000000185e2fbf0 -[UIApplication sendAction:to:from:forEvent:] + 100 (UIApplication.m:5360) 13 UIKitCore 0x0000000185f5ba4c -[UIControl sendAction:to:forEvent:] + 128 (UIControl.m:871) 14 UIKitCore 0x0000000185cd72c8 -[UIControl _sendActionsForEvents:withEvent:] + 352 (UIControl.m:942) 15 UIKitCore 0x0000000185d73ae0 -[UIButton _sendActionsForEvents:withEvent:] + 160 (UIButton.m:4142) 16 UIKitCore 0x00000001860067c0 -[UIControl touchesEnded:withEvent:] + 536 (UIControl.m:637) 17 UIKitCore 0x0000000185acbd40 _UIGestureEnvironmentUpdate + 6708 (UIGestureEnvironment.m:653) 18 UIKitCore 0x0000000185afe8c8 -[UIGestureEnvironment _updateForEvent:window:] + 784 (UIGestureEnvironment.m:1332) 19 UIKitCore 0x0000000185b0ba68 -[UIWindow sendEvent:] + 4428 (UIWindow.m:3265) 20 UIKitCore 0x0000000185cbb318 -[UIApplication sendEvent:] + 828 (UIApplication.m:11864) 21 UIKitCore 0x0000000185adec30 __dispatchPreprocessedEventFromEventQueue + 7904 (UIEventDispatcher.m:2290) 22 UIKitCore 0x0000000185ad3a1c __processEventQueue + 6760 (UIEventDispatcher.m:2597) 23 UIKitCore 0x0000000185ad8ec8 __eventFetcherSourceCallback + 172 (UIEventDispatcher.m:2669) 24 CoreFoundation 0x000000018357c020 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 (CFRunLoop.c:1972) 25 CoreFoundation 0x000000018358cce0 __CFRunLoopDoSource0 + 208 (CFRunLoop.c:2016) 26 CoreFoundation 0x00000001834c6fe8 __CFRunLoopDoSources0 + 268 (CFRunLoop.c:2053) 27 CoreFoundation 0x00000001834cc7f4 __CFRunLoopRun + 820 (CFRunLoop.c:2951) 28 CoreFoundation 0x00000001834e03b8 CFRunLoopRunSpecific + 600 (CFRunLoop.c:3268) 29 GraphicsServices 0x000000019ee7038c GSEventRunModal + 164 (GSEvent.c:2200) 30 UIKitCore 0x0000000185e806a8 -[UIApplication _run] + 1100 (UIApplication.m:3493) 31 UIKitCore 0x0000000185bff7f4 UIApplicationMain + 2092 (UIApplication.m:5046) 32 SwiftUI 0x000000018b143258 closure #1 in KitRendererCommon(_:) + 164 (UIKitApp.swift:35) 33 SwiftUI 0x000000018b071534 runApp<A>(_:) + 252 (<compiler-generated>:0) 34 SwiftUI 0x000000018b052cb4 static App.main() + 128 (App.swift:114) 35 **APP-NAME** 0x0000000100fa08f0 $main + 28 (<compiler-generated>:10) 36 **APP-NAME** 0x0000000100fa08f0 main + 40 (TLContact.swift:0) 37 dyld 0x0000000101185a24 start + 520 (dyldMain.cpp:876) EOF

I have an app that supports only iOS 14 or higher. Can user with older version of iOS buy this app? I don't want unhappy customers. Does AppStore handle this automatically? Thanks in advance for response.

Can I add my app to the sharing popup menu? (Like Facebook, Twitter and other apps) I would like to share image from iPhone photo library to my app. If yes could someone please leave me some starting point (documentation link). I couldn't find it anywhere.

I've created this function for sharing image, but I have a problem. func shareImg(img: UIImage) {         let imageShare = [ img ]         let activityViewController = UIActivityViewController(activityItems: imageShare as [Any] , applicationActivities: nil)         activityViewController.popoverPresentationController?.sourceView = self.view         activityViewController.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)         activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.init(rawValue: 0)         activityViewController.completionWithItemsHandler = { (type, _, _, error) in             print(error)         }         self.present(activityViewController, animated: true, completion: nil)     } Every time I try to save image to photo library it gives me this error and it isn't saved.: Error Domain=ALAssetsLibraryErrorDomain Code=-1 "Unknown error" UserInfo={NSLocalizedDescription=Unknown error, NSUnderlyingError=0x282e0ff60 {Error Domain=PHPhotosErrorDomain Code=3303 "(null)"}} I've found that code 3303 refers to: ALAssetsLibraryWriteIncompatibleDataError And also it logs this into console: [ShareSheet] connection invalidated Can anyone please help me? Thanks in advance

I have an issue with my Apple Watch app extension. I don't know why but willActivate method in NotificationController is not being called. I am running it on new WatchOS 8 simulator. Any ideas what could be the problem and how to solve it? Thanks in advance

In Swift there is a UIScreen.main.brightness = 1.0. But I couldn't find anything similar in SwiftUI. I need to adjust brightness in my watch os app. Is it even possible? Thanks in advance
