Hi, I have a UIToolbar at the bottom of my screen. The UIToolbar is made of UIBarButtonItems. At some point, I change the status of some buttons to hidden: button.isHidden = true This works: the buttons become invisible. At a later point in the process, I turn the buttons visible again: button.isHidden = false This did work on iOS 18, and does not work with the iOS 26 SDK: the buttons remain hidden, even though the property has been set to false. Am I doing it wrong? Is there anything I can do to fix this?

Hi, I've tried adding Extensions (using ExtensionFoundation) to one of my iOS apps. They work using Xcode on my devices, but when I upload them to the AppStore, I get the following error: ITMS-90349: Invalid Info.plist value - The value of the EXExtensionPointIdentifier key, AsheKube.app.a-Shell.localWebServer, in the Info.plist of “a-Shell.app/Extensions/localWebServer.appex” is invalid. Please refer to the App Extension Programming Guide at https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/Action.html#/apple_ref/doc/uid/TP40014214-CH13-SW1. I could not find relevant information on the web page pointed. I've tried different values for the "EXExtensionPointIdentifier", but none of them work. This value was generated by Xcode, since I did set the user-defined build setting EX_ENABLE_EXTENSION_POINT_GENERATION = YES, as explained in the instructions. At this point, I have no idea how to fix this issue.

Hello, this is very weird. I have an app where I use UIDocumentPickerViewController(forOpeningContentTypes: [.folder]) to let the users access to directories that are in the sandbox of other apps. It's been working since iOS 13. On the beta versions of iOS and iPadOS 26.1 (betas 3 and 4), the second time the UIDocumentPickerViewController is presented, it becomes unresponsive, with a spinning wheel in the top right corner where the "Open" button should be. I have absolutely no clue what the issue could be. It doesn't seem to be a widespread issue, but I have also no idea on how to find the origin and fix it. As far as I can tell from the debugger, this line is executed: DispatchQueue.main.async { rootVC?.present(self.documentPicker, animated: true, completion: nil) } and then nothing else happens.

I have an iOS application that derives on UITextInput to enter text. I have also overridden pressesBegan() and pressesEnded() in order to have some extra keyboard management (auto-repeat, special actions for arrow keys, function keys...) That works well for single-character languages (most roman languages, such as English, French, etc). For multi-character languages (Chinese, Japanses, Korean, Hindi), I can detect that the keyboard has been set to that language, and switch back to the default version of pressesBegan(): if let keyboardLanguage = self.textInputMode?.primaryLanguage { if (keyboardLanguage.hasPrefix("hi") || keyboardLanguage.hasPrefix("zh") || keyboardLanguage.hasPrefix("ja") || keyboardLanguage.hasPrefix("ko")) { super.pressesBegan(presses, with: event) } } But that strategy fails with the Tiếng Việt Telex keyboard (for Vietnamese language input). The way that keyboard works (as you can see if you open a document in Pages) is that you type as you go: T-i-e-n-g V-i-e-t T-e-l-e-x and the system adds the relevant diacritics once you've finished a word, so typing "Tieng Viet Telex" gives you "Tiếng Việt Telex" on the screen. Is there any documentation on the inner workings of this specific keyboard? What should I do (or not do) in order to make my application compatible with Tiếng Việt Telex?
