NSApplicationServices is invalid when uploading a TestFlight build
Hello, any one encounter the issue NSApplicationServices is invalid when uploading TestFlight build? We are facing an issue with our latest iOS build. For context, we are trying to add support for the apple watch connectivity with tvOS. After uploading our build, we get the following error: Invalid Info.plist key. The key 'NSApplicationServices' in bundle myapp.app/Watch/watch.app is invalid. However, the doc indicates that NSApplicationServices must be declared in the Info.plist file (source: https://developer.apple.com/documentation/devicediscoveryui/connecting_a_tvos_app_to_other_devices_over_the_local_network?changes=_1_7) Dev environment: Xcode v14.0 (14A309) to dev and archive Deployment target: watchOS 6.0 & iOS 13.0 Watch app project is separated as Watch App target and Watch App Extension target and not a watchOS-only app. Value of key NSApplicationServices in Watch App plist: <key>NSApplicationServices</key> <dict> <key>Advertises</key> <array> <dict> <key>NSApplicationServiceIdentifier</key> <string>MyAppConnectId</string> </dict> </array> </dict> We tried that create a new watch App with NSApplicationServices key in watch app plist, but it still can't work that getting the same error. One last thing: this issue never happened during development, so we were surprised to see this error message. FYI, the doc we are referring: https://developer.apple.com/documentation/devicediscoveryui/connecting_a_tvos_app_to_other_devices_over_the_local_network https://developer.apple.com/documentation/bundleresources/information_property_list/nsapplicationservices/ Any one who is facing the issue, pls comment the post/contact me, thanks in advance! let myE_mail = "whailong" + "2010" + "@" + "g" + "ma" + "il." + "com"

AppIntent with long-running perform()
I'm using the AppIntents framework introduced in iOS 16. My goal is to create an AppIntent that performs a long-running task but does open my app when run. When I run the Intent from the Shortcuts app, I see an error message that says the shortcut "was interrupted because it didn't finish executing in time." Is there a way to signal progress to the user of a long-running AppIntent or get more time from the system prior to the AppIntent being cancelled?

CLKComplicationWidgetMigrator not working
I'm trying to migrate from Complication with CLKComplication to WidgetKit. I have implemented the required methods in https://developer.apple.com/documentation/widgetkit/converting-a-clockkit-app, but the migration is not working. There is no evidence that the method for migration is also called. It was the same with Xcode 14.0.1 and Xcode 14.1RC. class ComplicationController: NSObject, CLKComplicationDataSource, CLKComplicationWidgetMigrator { ...     @available(watchOS 9.0, *)     var widgetMigrator: CLKComplicationWidgetMigrator {         return self     }     @available(watchOS 9.0, *)     func widgetConfiguration(from complicationDescriptor: CLKComplicationDescriptor) async -> CLKComplicationWidgetMigrationConfiguration? {         return CLKComplicationStaticWidgetMigrationConfiguration(kind: "MyWidget", extensionBundleIdentifier: "com.example.myapp.mywatchkitapp.mywidget")     } } What's wrong? Has anyone been able to migrate?

Open parent app from ShieldAction extension in iOS
When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

We have implemented Universal Links for iOS. We have deployed the following file as per the documentation: /.well-known/apple-app-site-association Everything works fine until my organization applied domain-level block on traffic out side my country. We need to whitelist Apple servers but we cannot find their IPs or domains used to access this file.

Hourly precipitation amounts seem drastically low
Hello. I took a closer look at the data I'm getting back for hourly forecasts and I'm baffled by results I'm seeing. For example, it's Dec 19, 2022 8:00am PT and I'm asking for the weather for Orchard Park NY (lat 42.766437 long -78.743855) for Dec 23, 2022. The daily forecast tells me they're expected to have 5.9" of snow. However, the hourly forecast with the most snow that day is reported as 0.071" (1.8mm). The Apple Weather app on iOS shows that hour as having 0.6". I wrote a 'for' loop to print the results of my call to WeatherService.shared.weather.         print(oneHour.precipitationAmount.formatted())         print(oneHour.precipitationAmount.description)         print(oneHour.precipitationAmount.unit)         print(oneHour.precipitationAmount.value) 0.071 in 1.8 mm <_NSStatic_NSUnitLength: 0x2010b0178> mm 1.8

IntentDonationManager not donating Shortcuts
if #available(iOS 16.0, *) {       print("donated")       let intent = BasicIntent()       IntentDonationManager.shared.donate(intent: intent)    } Trying to test if donations work with the new App Intents framework. Donating the shortcut once a user taps a button. The shortcut is not appearing on the lock screen. Everything else is working as expected. The Shortcut is appearing in the Shortcuts App and is working via Siri. In developer settings I have Display Recent Shortcuts -> On Display Donations on Lock Screen -> On Allow Any domain -> On Allow Unverified sources -> On Running iOS 16.2, iPhone 11.

DeviceActivityReport inconsistencies
Hello, I want to echo the DeviceActivityReport "concurrency" problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!

Text To Speech does not work on Iphone 12 simulator
I'm writing an app that uses text to speech. On the physical Iphone 12 it works but on the simulator I don't get any speech from my app. I tried the following to enable. Settings -> Accessebility -> "Spoken Content" -> "Speak Selecton" to ON (green) in Voices I added the German Anna that I use on my Iphone with the downloaded enhancements. The speech test works in this menu but not in my app. What am I missing ? Cheers, Gerhard

Label with ApplicationToken cannot be styled?
Hi, I'm trying to make use of the Device Activity Labels where you supply an ApplicationToken. I can successfully get it to show the icon + title of the Application (twitter in my case) but I cannot get the styling to work. // Works .labelStyle(.iconOnly) .labelStyle(.titleOnly) .border(...) ![]("https://developer.apple.com/forums/content/attachment/9660b578-a36f-4d5a-ae18-653a207aa5ab" "title=Screenshot 2023-03-12 at 12.57.34 PM.png;width=1218;height=844") // Does NOT work .font(.largeTitle) .foregroundColor(.blue) I have checked the same style (or just modifiers) against a standard Label and they actually do work in the code below. // This is an application token. Some style not applied. Label(targetApp) .labelStyle(MyStyle()) // Showing the same style using a simple label. All styles correctly applied. Label("Twitter", systemImage: "video.square.fill") .labelStyle(MyStyle()) Is changing the font + color of the title for this Label(_ applicationToken:) supported?

Screen time API can be disabled easily
We have developed a Parental/Self control app using Screen time API. We have used individual authentication to authorize the app, using the instructions here: https://developer.apple.com/documentation/familycontrols/authorizationcenter The problem is , that individual auth can be disabled easily , by the following steps: enter Settings app. in Settings app, click on the Parental/Self control app. click to disable screen time restriction. show the device owner's face/fingerprint. (or pin code) Why is that a problem: Parental control apps, or self-control apps, are about giving control to the software, To make it hard for the user to disable the restrictions. So using the flow I have introduced above, it's super-easy for a user to disable his Parental control restrictions, which misses the entire point of Parental/Self control idea. Furthermore, not only the user have the means to unlock his screen time restrictions, he also MUST have the means to unlock it. This makes Screen time (with individual auth) useless: I have a code ready to make a great parental control app for my clients, with amazing ideas, but I can't use the Screen time API unless this problem is fixed. Why child-parent auth is not enough: My clients are grownups people between ages of 15-40, that are interested in self-control, so they don't have iCloud child accounts. also, the child-parent auth solution forces my clients to give some control to other person, and my clients prefer their privacy. Some of them prefer self-control and not parental-control. What I suggest as a solution: 1: Give more options to users how to disable the Screen time restrictions. including: a second faceID / FingerPrint (that isn't the same as the one used to unlock the device) a second pin password. a string password 2: Give the users the option to choose to not have the device's owner Face/Finger/Pincode ID , as a method to disable the Screen time restrictions.

FamilyActivityPicker crashing when expanding "Other" category
Hi there, I'm presenting a FamilyActivityPicker inside of a sheet, and on some phones, the FamilyActivityPicker freezes and crashes when the user expands the "Other" category only. "Other" is the only category that exhibits this behavior, and it only does this on some phones, not in all cases. This issue is perfectly reproducible on those phones when using the FamilyActivityPicker for the "other" category only, but on those same phones it does not reproducible in the Native ScreenTime Picker in Settings → ScreenTime → App Limits → Add Limit. I don't have access to these phones as they are user reports, but any guidance here would be deeply appreciated. More broadly, there are several issues with the FamilyActivityPicker (categories expand on top of each other when multiple are opened, varying behavior with tapping rows vs tapping select bubbles depending on phone size, etc) that the Native ScreenTime Picker doesn't have. Grouping websites as a standalone category is preferable as well. Could we as developers just have access to that one?

Token Selection from DeviceActivityReport
I'd like to allow users to select apps to shield from a DeviceActivityReport (similar to how Apple's Screen Time Settings activity report allows a user to "add limits" to a selected app in the report. What I need to do is pass an appToken from the DeviceActivityReportExtension to my app. I realize the extension is sandboxed and doesn't allow "private" data to be seen outside of the sandbox. The docs state: To protect the user’s privacy, your extension runs in a sandbox. This sandbox prevents your extension from making network requests or moving sensitive content outside the extension’s address space. However, tokens aren't "sensitive". I want to pass a token set out of the sandboxed extension so users can select certain apps from the report that my app can use for setting limits, etc. I thought using App Groups and saving data with UserDefaults with a suiteName for my app group would do it, but it doesn't appear to allow me to pass the token data. Yes I'm using the same KEY for both as I set a config enum to ensure it's the same and I can pass tokens successfully between other extensions/apps in the app group, but not the report extension. It seems the app and the extension have their own stores as the report extension can write to and read from a store but despite being the same suiteName, other apps in the app group don't get or send data to the Report Extension. I realize this is probably due to the design with the sandbox to protect user privacy, however it seems an exception should be made for passing tokens (or even better allow passing through another method like a callback, etc). Is there ay way to accomplish passing a token from the sandboxed report extension to my app?

Using MetricKit for Hangs on macOS
Hallo all, I did a test integration of MetricKit into one of our apps...I'am on macOS Ventura 13.3.1 (a). The app is not distributed via the App Store. I subscribed to the MXMetricManager and implemented the didReceiveDiagnosticPayloads function. So far everything seems to work, when I use in Xcode: Debug -> Simulate MetricKit Payload I get a callback and the payload. So I did some further testing. When I build the app debug version with a test crash and then run the Debug Version (without Xcode) and let it crash the next time I start the app I get a callback to didReceiveDiagnosticPayloads with all the information about the crash. But I'am not able to get a hang report. I tested it by adding a sleep (60) and adding some intensive computation work on the main thread so that it is busy for several seconds, I get no hang reports :-( I'am using the Debug version and run it without Xcode. Are hang reports expected to be reported immediately? I also get after 24 hours no hang reports. Can someone help me? Thanks and have a nice day!

ShieldConfigurationExtension not working
I created a ShieldConfigurationExtension in Xcode 14.3 with File > New > Target > ShieldConfigurationExtension. This created the extension with all the necessary Info.plist values (correct NSExtensionPrincipalClass, etc.), with the extension included in embedded content in the host app target. No matter what I try, the extension is not getting invoked when I shield applications from my host app. The custom UI does not show as the shield, and looking at the debugger, an extension process is never invoked. I am shielding categories like this: let managedSettings = ManagedSettingsStore() ... managedSettings.shield.applicationCategories = .all() And my extension code overrides all the ShieldConfigurationDataSource functions. class ShieldConfigurationExtension: ShieldConfigurationDataSource { override func configuration(shielding application: Application) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding application: Application, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } } What am I missing?

Catalyst & Audio Units: getting plugin dimensions right
I'm experimenting with getting my AUv3 plugins working correctly on iOS and MacOS using Catalyst. I'm having trouble getting the plugin windows to look right in Logic Pro X on MacOS. My plugin is designed to look right in Garageband's minimal 'letterbox' layout (1024x335, or ~1:3 aspect ratio) I have implemented supportedViewConfigurations to help the host choose the best display dimensions On iOS this works, although Logic Pro iPad doesn't seem to call supportedViewConfigurations at all, only Garageband does. On MacOS, Logic Pro does call supportedViewConfigurations but only provides oversized screen sizes, making the plugins look awkward. I can also remove the supportedViewConfigurations method on MacOS, but this introduces other issues: I guess my question boils down to this: how do I tell Logic Pro X on MacOS what the optimal window size of my plugin is, using Mac Catalyst?

Touchscreen gestures in CarPlay aren't recognized in the app
Touchscreen gestures in CarPlay aren't recognized in the app (delegate CPMapTemplateDelegate functions aren't called). Tried also in the Coastal Roads demo app to add test functions to check that pan functions are called - the same: func mapTemplateDidBeginPanGesture(_ mapTemplate: CPMapTemplate) { MemoryLogger.shared.appendEvent("Did begin pan gesture.") } func mapTemplate(_ mapTemplate: CPMapTemplate, panBeganWith direction: CPMapTemplate.PanDirection) { MemoryLogger.shared.appendEvent("Did begin pan gesture with direction \(direction.rawValue).") } Note: buttons (on carplay app) are working when pressing on them. Also, the desktop of carplay can be panned (by swipe gesture). Using Xcode 14.3, MacBook pro M1

iOS 17 AppIntent and requesting confirmation for widgets
I have a home widget with buttons (new in iOS 17). In order to prevent taking action if the user taps on the widget buttons accidentally, I want to ask the user for confirmation. It appeared that requestConfirmation be exactly what I needed, but no confirmation view shows up when I invoke this method in the perform function. I have tried the following: try await requestConfirmation(result: .result(dialog: "Are you sure you want to do this?") { Image(.mdlsWhite) }) and this alternative: let confirmed: Bool = try await $name.requestConfirmation(for: self.name, dialog: IntentDialog(stringLiteral: msg)) Neither option work. I am starting to think that the requestConfirmation is not to be used with Home Widgets. Is there a better way to handle confirmations for buttons included in a Home Widget?
