I just noticed this today while building a React Native app. Anybody else seen this and know what it means/how to track it down/how to fix it

If I run the following code in didFinishLaunchingWithOptions() UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in if granted { DispatchQueue.main.async { application.registerForRemoteNotifications() } } } Then the result is that didRegisterForRemoteNotificationsWithDeviceToken() gets called. However if I change the code to be just: DispatchQueue.main.async { application.registerForRemoteNotifications() } Or as as its already running on main in this scenario, then just application.registerForRemoteNotifications() Then didRegisterForRemoteNotificationsWithDeviceToken() does NOT get called, but also neither does didFailToRegisterForRemoteNotificationsWithError(). Obtaining a push token is supposed to be independent of the user granting notifications permissions, so why am I not observing that behavior? I only observe this behavior when running on hardware, when running on the simulator both forms of the code work. Yet its nothing to do with my phone not being able to contact the Apple servers etc. - if I change the code back and forth back and forth between the two then if 100% works when using requestAuthorization() and 100% doesn't when not using it. There's nothing additional or out of the ordinary with the code, its standard app delete template stuff. Why isn't it getting a push token when requestAuthorization() isn't used? (I've tried adding an async delay to calling registerForRemoteNotifications(), but it made no difference).

How can experimentation and testing calling the AgeRangeService.shared.requestAgeRange() functionality be recreated easily? The very first time I ran this the OS popped up a dialog, however it won't do so again, even after the app is deleted and the device re-started. If one navigates to Settings/User/Personal Information/Age Range for Apps/Apps that have requested your age range appear here. Then the names of apps appear here even after the app has been deleted. Therefore how can it be removed from this section? Erasing and resetting the phone will presumably reset things back to a state such that the dialog can be presented again. But doing that and having to wait for that to complete each development or test run is impractical. Is there an alternative?

On this page: https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox It says: Start with a Sandbox account. What is a Sandbox account and how does one set one up? Just it just simply mean an Apple account id used for testing, or something else?

In the summary documentation about the declared Age Range API:https://developer.apple.com/news/?id=2ezb6jhj It states: "The API will also return a signal from the user’s device about the method of age assurance, such as credit card or government ID" But if the api itself, and its documentation is examined, there is no such mechanism nor mention of it: https://developer.apple.com/documentation/declaredagerange/agerangeservice So my question is, is the first documentation incorrect, if not, then where and how to access the method of age assurance?

From watching the video on App Attest the answer would appear to be no, but the video is a few years old so in hope, I thought I would post this question anyway. There's several scenarios where I would like a notification service extension to be able to use App Attest in communications with the back end(for example to send a receipt to the backend acknowledging receipt of the push, fetching an image from a url in the push payload, a few others). Any change App Attest can be used in by a notification service extension?

I'm working on an out-sourced application for a company and when a version of it built using ids and provisioning profiles from my Apple account it runs without problems. However when it is built and run using the company's ids and provisioning profiles I am seeing an issue with it. What is happening is when a notification service extension uses a call extension then the OS logs: doQueryCallExtensionStatusWithDispatchGroup() COMPLETED WITH ERROR: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.CallKit.CallDirectory was invalidated: failed at lookup with error 159 - Sandbox restriction." UserInfo= NSDebugDescription=The connection to service named com.apple.CallKit.CallDirectory was invalidated: failed at lookup with error 159 - Sandbox restriction. I noticed that in the company's provising profile for the notification service extension the app identier prefix is different from the team identifer. In my own provisioning profile the app identifier prefix and team identifer are the same. Could it be the case that this difference in identifiers within the provisioning profile is leading to the sandbox error message? Attached is the notification service extension provisioning profle provided to me by the company (converted to a .plist for readability)

I've added a background downloads extension to my app and added device console logging to every method in the placeholder code created by XCode, then installed the app to the phone. When I run the following command: xcrun backgroundassets-debug --app-bundle-id com.myCompany.myApp  --device-id 00008110-001E0DDA0AB8801E --simulate --app-update  and watch the console log - there's none of my logging from within the extension. In the OS log I can see this: error 11:24:41.550702-0700 backgroundassets.user Event (1) dropped for client () failed because client Info dictionary is missing its 'BAManifestURL' key. The template generated code says this: "The manifest that is downloaded is determined by BAManifestURL defined in the application's Info.plist" So I tried adding a key of BAManifestURL with a url hoping to initially just get the extension launching. But I still get the error saying the info dictionary is missing the BAManifestURL key. So exactly how should the BAManifestURL key value pair be added to the info.plist?

I've added a background asset extension and am trying to invoke it using this: xcrun backgroundassets-debug --app-bundle-id com.myCompany.myApp  --device-id 00008120-000225060C9B401E --simulate --app-update  When I run that command I see this in the phone's log: Unable to observe extension for (com.cequint.myapp), the BAApplicationInfo is missing an extensionIdentity. So how should an extension identify be added? The extension's info.plist is as created by the Xcode template: <key>EXAppExtensionAttributes</key> <dict> <key>EXExtensionPointIdentifier</key> <string>com.apple.background-asset-downloader-extension</string> </dict> And I've added the following to the app's info.plist: > <dict> <key>BGTaskSchedulerPermittedIdentifiers</key> <array> <string>kBackgroundTaskIdIdentifier_RNScheduleAppRunEvent</string> </array>   <key>BAMaxInstallSize</key>   <integer>3221225472</integer>   <key>BAInitialDownloadRestrictions</key>   <dict>          <key>BADownloadDomainAllowList</key>          <array>                 <string>*.drive.google.com</string>          </array>          <key>BADownloadAllowance</key>          <integer>2147483648</integer>   </dict> <key>BAManifestURL</key> <string>https://drive.google.com/file/d/1doJtzxBKCoVHEF80sndK6VskCrkD9H9r/view?usp=sharing</string> What else needs doing to provide the extension identifier the OS is saying is missing? (Using Xcode 14.1 and iOS 16.2)

Apple this is dead easy and quick to reproduce. Just create an app and then add a target of type background download. Xcode automatically assigns a group id to the target and generates a corresponding entitlements file like so: However the extension will not build, there is this error: You can bugger about in the developer portal as long as you want, ensuring the group identifier exists, ensuring provisioning profiles have this group capability, etc. etc. nothing will make this error go away. Now, what is unique about the download extension's entitlements file is the com.apple.developer.team-identifier key. This does not get generated for other extension - go ahead and see for yourself, create an action extension and give it a group, the result is its group appears in the entitlements file but not this com.apple.developer.team-identifier. If you try to print out $(TeamIdentifierPrefix) (via echoing it in a build script), you get this /Users/me/Library/Developer/Xcode/DerivedData/experiments-clpwbtcvdpqwuodxzwmsxwpztguo/Build/Intermediates.noindex/experiments.build/Debug-iphoneos/backgroundDownloadExtension.build/Script-243C9904292461BC001FDE14.sh: line 4: TeamIdentifierPrefix: command not found Hmm, command not found, but if you change the echo to ${TeamIdentifierPrefix} guess what gets printed, yes the team identifier i.e. in my case MV8J9D3236. Now if in the entitlements file I add the team identifier explicitly, like so Then magically the error about automatic signing and the provisioning profile goes away. Change it back to $(TeamIdentifierPrefix) and the error appears, change it to be explicit and it goes away. So by tweaking the entitlements file its possible to get the extension to build, however all is not well, now that it builds, if the extension is installed and run, the OS says: "Event (1) dropped for client (com.company.experiments) failed because the app and extension do not share any application groups." It says that despite the fact the app and extension both do have the same group capability. This is driving me nuts - the auto generated entitlements file is stopping the extension from compiling, but if you fix the build, it can't run. (Xcode 14.1, iOS 16.2)

If the code below is run it causes an exception 'NSInvalidArgumentException', reason: '-[__NSCFType set]: unrecognized selector sent to instance 0x283130be0' However, the exception can be removed by reducing the width value from 100.0 in positionRect, for example setting it to something like 50.0 removes the exception. But why is this? With a width value of 100.0 specified for positionRect, that's well short of the width of imageSize. And even if there is some size issue, why is there an unrecognized selector exception? let imageSize = CGSize(width: 400, height: 100) let testRenderer = UIGraphicsImageRenderer(size: imageSize) let testImage = testRenderer.image { context in context.cgContext.setFillColor(UIColor.black.cgColor) context.fill(CGRect(origin: .zero, size: imageSize)) let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.alignment = .left let attributes: [NSAttributedString.Key: Any] = [ .font: UIFont.systemFont(ofSize: 8.0), .paragraphStyle: paragraphStyle, .foregroundColor: UIColor.white.cgColor ] let attributedString = NSAttributedString(string: "This is some text", attributes: attributes) let positionRect = CGRect(x: 10, y: 10, width: 100.0, height: 8.0) attributedString.draw(with: positionRect, options: .usesLineFragmentOrigin, context: nil) }

I've been successfully using CXProvider.reportNewIncomingVoIPPushPayload() as follows: a (non VoIP) push is sent to the handset this is intercepted by a notification service extension the extension calls CXProvider.reportNewIncomingVoIPPushPayload() (the extension has the required com.apple.developer.usernotifications.filtering entitlement) this results in the app delegate's implementation of PKPushRegistryDelegate:didReceiveIncomingPushWithPayload getting called (the app is launched if terminated) This all works as expected, in particular when the app is terminated it still works. However its suddenly stopped working since my phone got updated to iOS 16.6 (I can't remember exactly what was on it previously, 16.5 or 16.4). Now with iOS 16.6 the behavior is that PKPushRegistryDelegate:didReceiveIncomingPushWithPayload() only gets called if the app is not terminated. If the app is terminated then calling CXProvider.reportNewIncomingVoIPPushPayload() results in the app getting launched and didFinishLaunchingWithOptions() getting called BUT didReceiveIncomingPushWithPayload() is not called when launching from a terminated state. As a consequence of didReceiveIncomingPushWithPayload() not getting called, the app isn't calling reportNewIncomingCallWithUUID() and so after a few runs the OS stops launching the app entirely saying: "Application will not be launched because it failed to report an incoming call too many times". When didFinishLaunchingWithOptions() is called the launchOptions are nil, i.e. there is no way to distinguish the app from being launched as a consequence of reportNewIncomingVoIPPushPayload()(*) being called and therefore it is not possible to call reportNewIncomingCallWithUUID(). So this feature is totally broken apparently from previous behavior. Any comment? TIA (*)Well actually, the extension could write a flag to a shared group and the app read that on launch, but what a hack, and should be unnecessary.

Our app has some Crashlytics & Localytics reporting to collect metrics for diagnostic and info gathering. One thing I'm noticing recently is that if a user has version m of the app installed and updates to version m+1, then for some users, the app has detected and reported that the push token obtained with version m+1 is different from that of version m (for the same handset). That's fine - if the app has detected the change to the token it can send the new one to the server so the server can update. But my question is - if the user didn't explicitly launch the app and thus present the app with the chance to send the new token to the server, then what will happen to the pushes sent by the server using the old token? Presumably they won't get delivered if the token has changed, but if the user has no need to launch the app then they're never going to receive any pushes from the server until they do launch the app. However there's not necessarily any reason why a user should repeatedly launch an app once it's been set up (depending upon what it does and how it delivers info to the user and how the user interacts with it, there's no reason why a user should have to launch the app after initial installation and launch). If so then this seems like a gap in the design of push notifications? If they can change on the same handset, or another scenario is the user backs up their device to iCloud and then restores to a different handset, then in that case the push tokens will have definitely changed, yet any apps using push don't get the chance to send the new token to the server until the user launches the app, meanwhile all pushes from the server will be dropped.

I don't follow the section in the wwdv video on http3 https://developer.apple.com/videos/play/wwdc2021/10094/ From about 07.00 onwards for a couple of minutes, the presenter says URLSession won't use http3 unless the server advertises it. Then he uses instruments to show the app is using http2 - BUT the server is advertising http3. Then he says the fact the server advertised http3 will be remembered for future sessions. Why does the app use http2 for the first session even though the server advertised http3? Does that mean the first time any app connects to a http3 server it'll actually be http2 and only http3 for subsequent connections?

I've got an app which has a notification service extension (and has had so for a few years). I noticed that the pushes were getting delivered directly to the user for a handset, and in the log could see a SpringBoard error saying Error Domain=PluginKit Code=4 RBSLanchRequest error trying to launch plugin Error Domain=RBSRequestErrorDomain Code=5 Launch failed ErrorDomain=NSPOSIXErrorDomain Code=111 Unknown error:111 I rebooted the phone and it started working as expected. But it's worrisome this happened, and it's not the first time I've seen it either. Observed with iOS 17.3.1
