SwiftUI List performance

Project Background： I am developing a third-party custom keyboard for iOS whose primary feature is real-time voice input. In my current design, responsibilities are split as follows: 1. The container (main) app is responsible for: Audio recording Speech recognition (ASR) 2. The keyboard extension is responsible for: Providing the keyboard UI Initiating the voice input workflow Receiving transcription results via an App Group Inserting recognized text into the active text field using textDocumentProxy.insertText(_:) Intended User Flow The intended workflow is: The user is typing in a third-party app (for example, WeChat) using my custom keyboard. The user taps a “Voice Input” button in the keyboard extension. The keyboard extension activates the container app so that audio recording and ASR can begin. After recording has started, control returns to the original app where the user was typing. The container app continues running in the background, maintaining active audio recording and ASR. Recognized text is co

I'm trying to implement a feature whereby a user can tap a button to insert a character at the cursor in a TextField - the cursor then needs to be moved forward to be in front of the insert character. I'm having trouble with characters such as π which are UTF16 encoded. In the following sample app, enter the following sequence: Enter 9 by keyboard tap + Enter 9 by keyboard tap π Enter 9 via keyboard tap + he TextField will show '9+9π+9' (i.e. the final + is inserted before 9 rather than after it. Any insight into what I am doing wrong? import SwiftUI @main struct TextInsertApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { @State private var text: String = @State private var selection: TextSelection? = nil var body: some View { TextField(, text: $text, selection: $selection) .background(.gray.opacity(0.4)) Button(+) { insert(+) } Button(π) { insert(π) } } func insert(_ insertString: String) { if let selection { if case let .selection(range) = selection.ind

I have been fighting this problem for two months and would love any help, advice or tips. Should I file a DTS ticket? Summary We attach a JPEG image to a local notification using UNNotificationAttachment. iOS reports the delivered notification as having attachments=1, but intermittently no image preview appears in Notification Center. In correlated cases, the attachment’s UNNotificationAttachment.url (which points into iOS’s attachment store) becomes unreadable (Data(contentsOf:) fails) even though the delivered notification still reports attachments=1.

Hello, I am trying to enroll in the Apple Developer Program, but I am unable to complete the payment and account creation process despite trying multiple times and following all recommended steps. Please note that I am attempting to complete this purchase from Turkey. Below is a detailed list of everything I have tried so far: I tried using different web browsers (Opera, Google Chrome). I tried multiple different debit cards. I also tried using a credit card. I created a brand new Apple ID and attempted enrollment with it. I tried both Gmail-based Apple ID and iCloud-based Apple ID. I attempted to enroll via the Apple Developer app on an iPhone 11. All my card details are correct, and domestic & international transactions are enabled. My address information is correct. I tried both Turkish characters and English characters. I also tried using a VPN, but the issue still persists. Despite all of these attempts, I am still unable to purchase the Apple Developer Program membership. I have contacted s

To whom it may concern that deals with bugs in SwiftUI for iOS 26: Inadvertently discovered a bug which duplicates ToolbarItem in any placement in the toolbar when navigationBarBackButtonHidden is set to true. .toolbar{ ToolbarItem(placement: .confirmationAction) { Button(Stop, systemImage: stop.fill){ //some action } } } .navigationBarBackButtonHidden(true) Expected Behavior Show the ToolbarItem Actual Behavior Duplicates items in the placement position. Thank you.

Hello, I have a SwiftUI View sitting in the UIHosting view controller. On rotation to landscape, the system would add padding to the toolbar. I presume it's the nav bar. Anyone experienced this? What would be this space? padding? content margin?

I have a bunch of Buttons with a .help(Text(Help text)) modifier, inside of a VStack which has its own .help() modifier describing the entire section. The VStack help shows up only when I hover over the buttons, and the Button help never shows at all. If I comment out the VStack help, the individual button helps show. How do I get both to show up properly? I want the VStack to show if I am in the roundedBorder, unless I am over a Button with its own .help modifier. import SwiftUI struct BugReport: View { @State private var testp1 = false @State private var testp2 = false var body: some View { VStack { Text(Hello, World!) Button(Test1) { testp1.toggle() } .help(Change the test1) Button(Test2) { testp2.toggle() } .help(Change the test2) } .help(Testing stuff) .roundedBorder(color: .black) } } #Preview { BugReport() }

My main app target builds fine and can run on Simulator without issue. Whenever I try to run a Preview, I get this error: == DATE: Monday, November 3, 2025 at 2:52:23 PM Pacific Standard Time 2025-11-03T22:52:23Z == PREVIEW UPDATE ERROR: SimulatorShutdownUnexpectedlyError: Simulator was shutdown during an update Simulator [F85A5AF1-F52C-4662-AFCD-762F87AF537D] failed to boot and may have crashed. This seems like it started happening after updating to MacOS 26. I've tried reinstalling all Simulators, tried on Xcode 26, deleted derived data, restarted Xcode and my Mac several times. What other troubleshooting steps can I take?
