Support external cameras in your iPadOS app and use Swift to read multiple camera feeds? thanks

I found iPadOS18 displayed navigation bar incorrectly when transition from screen with hidden navigation bar to screen that show navigation bar. I have 2 ViewController: FirstViewController and SecondViewController. FirstViewController navigationBar set isHidden to be true (hidden) and SecondViewController navigationBar set isHidden to be false (showing). When transition from FirstViewController to SecondViewController, the navigation bar is displayed incorrectly as shown in picture below: Actual Expected Note I set hide navigation bar in viewWillAppear() in both ViewController override func viewWillAppear(_ animated: Bool) { navigationController?.setNavigationBarHidden(..., animated: true) } source code: https://github.com/ornthita/TestTabbar

After updating to 18.3 my iPad 7th generation has no sound and will not play videos

I see that UIScribbleInteractionDelegate has scribbleInteraction(_:shouldBeginAt:) that you can always return false from in order to disable scribble. Is there any way to disable it in a website via javascript or dom attributes?

Hi experts, When I open a USDZ file which contains perspective cameras by "Files" app in IOS 18.2/iPadOS 18.2, I can't see anything. And when I open the USDZ file in IOS 18.1/iPadOS 18.1, it works well. On the other hand, when I open a USDZ file which contains orthographic cameras in IOS 18.1 or IOS 18.2, the scene is stuck. Could you help to solve these issues please? Thanks.

We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered AppleArchive crashes instead of failing gracefully when decrypting a corrupt archive. As described in forum post 765101, UIDocumentPickerViewController can handoff a corrupt copy of an archive to UIDocumentPickerDelegate under specific circumstances. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with the bleeding edge iPadOS 18. Our app is primarily Objective-C, but it utilizes the Swift-based AppleArchive 'EncryptingAndDecryptingDirectories' sample code associated with WWDC21 session: 10233: Bring Encrypted Archives and Performance Improvements to Your App with Accelerate. The WWDC21 'EncryptingAndDecryptingDirectories' Swift sample project crashes in a similar manner when a corrupt archive file created by UIDocumentPickerViewController is dropped into the sample app's window for decryption (see attached crash log). Does anyone know if there's a workaround for the 'EncryptingAndDecryptingDirectories' sample project to prevent AppleArchive from crashing when decrypting a corrupt archive? crash log.txt
