I understand from the Xcode release notes that it is now possible to submit visionOS apps to TestFlight. I'm getting the error "Asset validation failed" "Invalid Provisioning Profile. This provisioning profile is not compatible with visionOS apps". when uploading to TestFlight. I use an Xcode managed profile, and am using the same bundle id as for the iOS and Mac versions of the app. In the "Certificates, Identifiers &amp;amp; Profiles" -&amp;gt; "Edit your App ID Configuration" it lists "iOS, iPadOS, macOS, tvOS, watchOS, visionOS" under "Platform". Is there some guidance on submitting visionOS apps to TestFlight? Any ideas on how to regenerate the profile to include visionOS apps? Thanks, Damian

Hi, I'm getting the error code -34018 in the VisionOS simulator when calling SecItemCopyMatching with this query: let getquery: [String: Any] = [kSecClass as String: kSecClassGenericPassword, kSecAttrAccount as String: name, kSecReturnData as String: kCFBooleanTrue!, kSecMatchLimit as String : kSecMatchLimitOne ] The console says: copy_matching Error Domain=NSOSStatusErrorDomain Code=-34018 "Client has neither application-identifier nor keychain-access-groups entitlements" UserInfo={numberOfErrorsDeep=0, NSDescription=Client has neither application-identifier nor keychain-access-groups entitlements} I'm NOT using groups. I've tried changing the bundle id. Xcode version 15.0 beta 2 (15A5161b) Anyone have any ideas? Anyone using the keychain in their visionOS app? :-)

When editing the Default workflow, if I toggle the "Clean" checkbox, the "Save" button does not become enabled, so I am unable to change the setting. I need to make another dummy change, such as adding a space to the workflow name, to allow me to save.

For the following code, the "Appeared..." label only gets displayed for the elements that are initially visible, when others are scrolled into view the onAppear does not get called on WatchOS. It just shows Appeared 1 Appeared 2 Appeared 3 Appeared 4 Appeared 5 Not appeared Not appeared Not appeared Not appeared ... even when the "Not appeared" elements are scrolled into view. struct PagesView : View {   var body : some View {     TabView {       List {         ForEach(Array(1...10), id: \.self) { v in           Row(number: v)         }       }     }   } } struct Row : View {   let number : Int   @State var label = "Not appeared"   var body : some View {     Text(label)       .onAppear {         label = "Appeared \(number)"       }   } } Does anyone know why this might be happening?

I have an app that is already in the store, - https://apps.apple.com/us/app/watchgit/id1515780045 that lets you use GitHub on your Apple Watch (yes really!). I submitted a bugfix update with no changes other than to fix a crash on launch on the Apple Watch, and my update was rejected. I have a phone app which I use to facilitate login, since logging in to GitHub on the Apple Watch isn't feasible. The phone app does nothing except let you login and logout. Because the app store only lets you show videos of phone apps, I embed within the phone app's home page (the only page) a video of the watch app in action. That way I can upload a video of the phone app to the store and people get to see the watch app in action. Despite being accepted the first time, the update was rejected for two reasons: Guideline 2.3.4 - Performance - Accurate Metadata Your app preview includes content that does not sufficiently reflect the app in use. Specifically, your preview: Includes device images and/or device frames. Next Steps To resolve this issue, please revise your app preview to only use video screen captures of the app, narration, and textual and design overlays. Resources For resources on creating great app previews, you may want to review the App Previews page. For more general information on how to make the most of your app's App Store product page, please see the App Store Product Page information available on the Apple Developer website. Guidelines 2.3.7 - Performance - Accurate Metadata We noticed that your app name or subtitle to be displayed on the App Store includes the following trademarked term or popular app name, which is not appropriate for use in these metadata items. Specifically, your app name or subtitle included the term, GitHub. The next submission of this app may require a longer review time, and this app will not be eligible for an expedited review until this issue is resolved. Despite my iPhone preview videos being exactly the same as the app's screen, with no manipulation or framing, it appears that they don't like the fact that I have embedded a video of the watch app within the iPhone app's screen. Also, because my app is a client for the GitHub service I need to state that in some way, but I have no idea as to what formulation of text, if any, would be acceptable. Questions: Does anyone have any guidance as to what I should do about the embedded video situation? Do I just give up on trying to show the watch app in action within the home screen of the iPhone app? Does anyone have any idea how I might refer to GitHub without being flagged for trademark violation? You can see the video and text in question in the app store: https://apps.apple.com/us/app/watchgit/id1515780045 I've updated the app and description to try to address the use of GitHub with a disclaimer and saying "for the GitHub service" but was rejected in the same way. My explanation that the iPhone video was an accurate reflection of the screen was also rejected: Regarding Guideline 2.3.4 - Performance - Accurate Metadata, we continue to find that the rejection is valid. Specifically, your preview includes device Images. To resolve this issue, please revise your app preview to only use video screen captures of the Watch app.

I'm using Xcode 12 beta 2, and the latest WatchOS beta. For the following code I see 02:03 (correct) in the simulator and preview, and 02:00 (incorrect) on the physical watch: import SwiftUI struct ContentView: View {   var body : some View {           VStack {       let a = 2       let b = 3       Text("\(a, specifier: "%02d"):\(b, specifier: "%02d") ")     }   } } struct ContentView_Previews: PreviewProvider {   static var previews: some View {     ContentView()   } } Is this a known issue, user error, or a bug? Thanks, Damian
