Hi, As you can see in the code below whenever I open the app in the normal mode app works fine and the detail view shows data properly. However, in split screen the app lost data of the selected item. I'm sure there is a bug in here unless I should manage it by myself which unacceptable! @main struct TestSwiftUIApp: App {     var body: some Scene {         WindowGroup {             ContentView()         }     } } struct Employee: Identifiable {     let name: String     let id: Int } struct ContentView: View {     @State     var selectedEmployeeId: Employee.ID?     let employess: [Employee] = [.init(name: "Hamed", id: 1), .init(name: "John", id: 2)]     var body: some View {         NavigationSplitView {             List(employess, selection: $selectedEmployeeId) { employee in                 Text(employee.name)             }         } detail: {             NavigationStack {                 if let employee = employess.first{$0.id == selectedEmployeeId} {                     EmployeeDetails(employee: employee)                 }             }         }     } } struct EmployeeDetails: View {     let employee: Employee     var body: some View {         Text("Detail of empolyee\(employee.name) with id: \(employee.id)")     } }

Apple Docs mentions that driver should be approved(enabled) in Settings app. I wonder is there any API available to check that driver is not enabled? To my mind, App with driver should have a following flow: Run App Check that driver is(not) enabled Display message(alert) and ask to enable driver in Settings. Optionally: provide shortcut to exact Settings page Unfortunately, it's not obvious how to check that driver is enabled.

We implemented communication between Swift App and DriverKit driver using IOConnectCallAsyncStructMethod. void USBDriverClass::registerAsyncCallback(){   // Async required variables   notificationPort = NULL;   machNotificationPort = NULL;   runLoopSource = NULL;       // Async initialization   globalRunLoop = CFRunLoopGetMain();   CFRetain(globalRunLoop);       notificationPort = IONotificationPortCreate(kIOMainPortDefault);   if (notificationPort == NULL)   {     printf("Failed to create notification port for application.\n");   }       machNotificationPort = IONotificationPortGetMachPort(notificationPort);   if (machNotificationPort == 0)   {     printf("Failed to get mach notification port for application.\n");   }       runLoopSource = IONotificationPortGetRunLoopSource(notificationPort);   if (runLoopSource == NULL)   {     printf("Failed to get run loop for application.\n");   }       // Establish our notifications in the run loop, so we can get callbacks.   CFRunLoopAddSource(globalRunLoop, runLoopSource, kCFRunLoopDefaultMode);       // Establish our "AsyncCallback" function as the function that will be called by our Dext when it calls its "AsyncCompletion" function.   // We'll use kIOAsyncCalloutFuncIndex and kIOAsyncCalloutRefconIndex to define the parameters for our async callback   // This is your callback function. Check the definition for more details.   asyncRef[kIOAsyncCalloutFuncIndex] = (io_user_reference_t)AsyncCallback;   // Use this for context on the return. For example you might pass "this". But since this example is entirely static, we'll skip that step.   asyncRef[kIOAsyncCalloutRefconIndex] = (io_user_reference_t)NULL;       kern_return_t ret = kIOReturnSuccess;   uint8_t words = 4;       size_t inputSize = sizeof(StructA);   StructA structA;       structA.tag = 1;   structA.length = 0;   structA.values[0] = 0x106000;   structA.values[1] = words * sizeof(uint32_t);       size_t outputSize = sizeof(OutputData);   OutputData data;   printf("registerAsyncCallback called");       ret = IOConnectCallAsyncStructMethod(connection, MessageType_RegisterAsyncCallback, machNotificationPort, asyncRef, kIOAsyncCalloutCount, &structA, inputSize, &data, &outputSize);   if (ret != kIOReturnSuccess)   {     printf("IOConnectCallAsyncStructMethod failed with error: 0x%08x.\n", ret);   } } And when we get data from device we send data back from Driver to Swift app ivars->mUSBProbeDriverClient->AsyncCompletion(ivars->streamingDataCallback, kIOReturnSuccess, asyncData, 16); Driver should transfer data to swift app asynchronously when it's provided by USB device so we can not transfer struct synchronously. Async call back has limitation of 16 of uint64_t only and our application require larger data transfer. The logical way to transfer data using a memory buffer and as per Apple documentation they are providing this using IODataQueueDispatchSource. But they have not provided any example or showed how to use this. How to use fill buffer and use it in swift app using IODataQueueDispatchSource?

Hi,i have been trying out SwiftUI Table and wanted to present a details view when click on Table Row occurs, but I couldn't figure out how to "deselect" row once its been selected, while it may not be what Table was intended for, but I still think this code should be valid. (iPadOS) struct Person: Identifiable { let givenName: String let familyName: String let emailAddress: String let id = UUID() } private var people = [ Person(givenName: "Juan", familyName: "Chavez", emailAddress: "juanchavez@icloud.com"), Person(givenName: "Mei", familyName: "Chen", emailAddress: "meichen@icloud.com"), Person(givenName: "Tom", familyName: "Clark", emailAddress: "tomclark@icloud.com"), Person(givenName: "Gita", familyName: "Kumar", emailAddress: "gitakumar@icloud.com") ] @State private var selectedPeople: Person.ID? @State private var detailsViewPresented: Bool = false var body: some View {         Table(people, selection: $selectedPeople) {             TableColumn("Given Name", value: \.givenName)             TableColumn("Family Name", value: \.familyName)             TableColumn("E-Mail Address", value: \.emailAddress)         }         .onChange(of: selectedPeople) { selection in             guard selection != nil else {                 return             }             detailsViewPresented = true         }         .sheet(isPresented: $detailsViewPresented, onDismiss: {             // Trying to reset the selection             self.selectedPeople = nil         }) {             Text("Person's details")         } } Here when I press row, it gets selected and Text is presented, but row still remains selected, and yes, I could just use onTapGesture within row content if I declared TableColumn with explicit content, but it would just be added to that column and would not provide build in selection style. https://developer.apple.com/documentation/swiftui/table

hey! i have an ipad pro 11’ 2018, and everything was working fine until one day i wasn’t able to connect my apple pencil 2 to my ipad. the pencil itself gets detected it just won’t connect with my ipad. i already tried restarting, unpairing (even since i wasn’t able to pair it) and even restoring my ipad. does anyone have a solution for this?

I'm working on a DriverKit driver. I have it running on macOS, including a very simple client app written in SwiftUI. Everything is working fine there. I've added iPadOS as a destination for the app as demonstrated in the WWDC video on DriverKit for iPadOS. The app builds and runs on my iPad, as expected (after a little work to conditionalize out my use of SystemExtensions.framework for installation on macOS). However, after installing and running the app on an iPad, the driver does not show up in Settings->General, nor in the app-specific settings pane triggered by the inclusion of a settings bundle in the app. I've confirmed that the dext is indeed being included in the app bundle when built for iPadOS (in MyApp.app/SystemExtensions/com.me.MyApp.MyDriver.dext). I also can see in the build log that there's a validation step for the dext, and that seems to be succeeding. I don't know why the app isn't being discovered -- or in any case surfaced to the user -- when the app is installed on the iPad. Has anyone faced this problem and solved it? Are there ways to troubleshoot installation/discovery of an embedded DriverKit extensions on iOS? Unlike on macOS, I don't really see any relevant console messages.

Hi, Has anyone else lost access to universal control with the security patch for OSX? I have 2 iPads and an M1 Mac mini all running the latest beta software but since the last security update this morning I have lost the ability to use universal control. Tha iPads can be seen and mirrored to and universal control is switched on but no luck. All working fine prior to latest beta's. Re-starts, toggling of bluetooth, wifi, handoff, universal control done on all machines to no avail. Anyone recommend how to fix this, greatly appreciated.

Hello so i have a few apps that im getting developed on upwork and i have practically 0 knowledge as far as how anything works as far as computer science type stuff. i just want to know what is the correct procedure as far as letting somebody upload the app to my apple developer account. do i give them my AppleID and password and let them do it and then change my password after they're done? any information would be greatly appreciated. thank you

Problem - any time I open up keyboard in any app, keyboard floats over page on the middle of the app blocking form input and is just a bad experience. Usage blocker. Has anyone seen this? very debilitating. ipad mini 6 ipados 1.16.4 - at the latest update as of writing this post. help! see in screenshot of this page the keyboard is right in middle of screen blocking actual input.

Given a document-based app (MyApp) using DocumentGroup: If MyApp is not open, or it is open with the Document Browser displayed, and a file compatible with MyApp is tapped in the Files app, the tapped document opens as expected in MyApp. If MyApp is open and displaying a document, then tapping a compatible document in the Files app switches to MyApp, but fails to display the tapped document, and logs the following error: [Presentation] Attempt to present <SwiftUI.UIKitNavigationController: 0x11c87dc00> on <SwiftUI.DocumentBrowserViewController: 0x129018a00> (from <SwiftUI.DocumentBrowserViewController: 0x129018a00>) whose view is not in the window hierarchy. The problem is easily demonstrated by creating a new project from the Document App template in Xcode and running it in the simulator Run the app and create a new document (Untitled) Close Untitled and create another document (Untitled 2) Close Untitled 2 Open Untitled Switch to the Files app, navigate to the MyApp folder and tap on Untitled 2 The error above will be shown in Xcode. Does anyone have any insight into how to solve this? Thank you

steps to reproduce: create a new iPad Playgrounds project implement the minimum viable app using DocumentGroup import SwiftUI import UniformTypeIdentifiers struct TextDocument: FileDocument { var text: String init(text: String = "") { self.text = text } static var readableContentTypes: [UTType] { [.plainText] } init(configuration: ReadConfiguration) throws { guard let data = configuration.file.regularFileContents, let string = String(data: data, encoding: .utf8) else { throw CocoaError(.fileReadCorruptFile) } text = string } func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let data = text.data(using: .utf8)! return .init(regularFileWithContents: data) } } @main struct MyApp: App { var body: some Scene { DocumentGroup(newDocument: TextDocument()) { file in TextEditor(text: file.$document.text) } } } I can compile and run the app, and use it to open and edit or create new plain text documents, but the App Preview crashes, saying "The requested index was outside the bounds of the array." and there's a red error badge on @main I assume this is a bug, and I've submitted a feedback (FB12194610) but I'm looking for ways to work around it in the meantime. There are two annoyances the red error badge obfuscates when i really do have errors in my code I don't have previews If I comment out the DocumentGroup code and insert a WindowGroup I can make the preview successfully load long enough that I can pause it. This fixes the error badge problem, but pausing the App Preview pauses all the view previews as well. And every time I run the project it restarts the previews. And I have to run the project pretty often because I can't use the previews! So I'm hoping there's a better workaround, either by more permanently disabling App Preview, or with something like the App Preview equivalent of PreviewProvider to give me some control over how the App Preview renders.

Is there a reason why neither HealthKit data nor the Health App is available on an iPad? And any suggestions how Apple could be convinced to enable that?

My confirmationDialog is part of my ContentView and within some View. It displays as expected in the iPhone simulator and on my physical iPhone. It does not display on either the iPad simulator or physical iPad. It fails silently and I'm not sure what could be the issue.

In the following code, click/touch anywhere on any row of the list deletes that row. This is not expected. Only the click/touch on the "xmark" button should delete that row. import SwiftUI struct MainView: View { private let arr: [String] = ["one", "two", "three"] var body: some View { List(arr, id: \.self) {item in SecView(name: item) } } } struct SecView: View { var name: String @State private var show = true var body: some View { if show { HStack { Text(name) Button(action: { show = false }, label: { Image(systemName: "xmark") }) .border(.yellow) } } } } @main struct XApp: App { var body: some Scene { WindowGroup { MainView() } } } Please check. I ran the above code for iPAD air (5th generation).

Hello, is there any offical and always actual URL where I can get a list of all released OS versions (iOS, macOS, iPadOS etc) with release date as XML or JSON or other machine readable file format? I need this list to manage and monitor our corporate managed devices in different update rings. Thx for help.

I am trying to connect to a socket using a url, which I can confirm connects successfully when using a socket connect tool, but when I try using URLSessionWebSocketTask it fails with the error: Note: have had to replace url domain and endpoint with *example.com/endpoint` for work reasons ... NSLocalizedDescription=A server with the specified hostname could not be found.} FAIL: Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo={NSErrorFailingURLStringKey=https://example.com/endpoint, NSLocalizedDescription=A server with the specified hostname could not be found., NSErrorFailingURLKey=https://example.com/endpoint} The url I provide starts with the wss prefix: let socketUrl = "wss://example.com/endpoint" ... webSocketTask = urlSession.webSocketTask(with: socketUrl) webSocketTask?.resume() but the error posted earlier indicates that the task is trying to connect using https instead (which the server does not support). I don't remember having to setup anything last time, but it has been about a year since working with these things. Have I missed something setup or app transport security settings etc?
