How to reset Keychain "certificate is not trusted" error caused by VPN, without rebooting?
If I turn on (my company supplied VPN access) and then attempt to build with Xcode then that has the consequence that all the dev/distribution certificates in the keychain turn red and say "certificate is not trusted". Turning off VPN doesn't reset them back and of course re-attempting to build will fail. However if I reboot my MacBook, then the keychain is back in a good state again. However as I work remotely I constantly have to flick VPN on and off throughout the day, and having to reboot endlessly is a pain. Is there something I can do to reset the Keychain's certs to a good state without having to reboot? (and without having to delete them all and re-add them all back to the keychain).

Is there any way of adjusting logging level dynamically at run time?
I've gone through several tutorials, and the documentation, it seems there's no way to adjust the logging level dynamically, or even at build time for that matter. i.e. there is apparently nothing that exists such as: static let logger = Logger(subsystem: subsystem(), category: category()) logger.setMinimalLevel(.Warning) logger.trace("I won't get displayed because minimal level is debug") Am I mistaken and there is something like this?

With Xcode 15 how do you turn off Connect via network for devices?
I have a lot of phones and constantly switch between them, its very very annoying that when a phone is connected via cable, and then swapped out with another one, then Xcode will continue to install/run with the phone that's just been switched out, not the one that's just been connected by cable. This is because Connect via network it turned on and there's no way to turn it off. In previous versions of Xcode you could turn this on/off as you wished, not so with Xcode 15, it decides to turn it on for you and won't let you turn it off because its always disabled.

Is there a way of accessing/viewing files in an iOS app's shared group location from a Mac?
My goal is to try and get a unified logging system set up where logging from an iOS app and its extensions (primarily a notification service extension) get written into one central repository. So I was planning on setting up CocoaLumberjack in the app and the extension to use the same file path/name, adding the group capability to the app and the extensions and specifying the shared group directory as the file path. By default, for an app, CocoaLumberjack writes its files to: var/mobile/Containers/Data/Application/05464D4A-20F6-4E1F-9DBC-3109C053A1E8/Library/Caches/Logs/ On a Mac using an application such as iExplorer the above file and be located and viewed and copied etc. For an extension, it writes them to: /var/mobile/Containers/Data/PluginKitPlugin/5542F5EA-EB3A-4728-B33E-4E57C1B7B3B4/Library/Caches/Logs/ Now if I configure Cocoalumberjack to instead write the logger file to the shared group directory, then that will be at: /private/var/mobile/Containers/Shared/AppGroup/6CD5AF2C-54C9-46EF-B831-997B1DD6664F/ However its not possible using iExplorer to access this location. Using a Mac connected to the iPhone, is there an app or tool etc., that will enable me to locate the log file if it's created in the above AppGroup location?

Push token change on app upgrade
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.

Xcode 15.0 Beta 6 is unusable due to hanging installation and attaching phases
The previous betas have all been ok, but beta 6 is for me totally and utterly unusable because it keeps hanging forever during the installation and attaching phases when trying to run an app (attached physically via cable, not bluetooth). The first time or two of making a code change, then running, its ok, but then its guaranteed to hang eventually, it gets stuck on the "Installing app to iPhone" phase. If I restart the phone and try again it might get past that, but then it just gets stuck on "Waiting to attach to app on iPhone" phase. I know its beta software and not expected to be perfect, but its unusable and previous beta versions are no longer available to rollback to. Has anybody encountered this before and knows of any tricks to get it to stop hanging and load/run the app? (Restarting Xcode, restarting the phone, re-building, does not fix it for me)

CXProvider.reportNewIncomingVoIPPushPayload() behavior changed with iOS 16.6
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.

OSLog: anyway to get unified/combined logging from app and app extensions?
I've got a complex app extension and I'd like to be able to combine the logging from the app and the extension into a single file (for extraction/uploading etc.) I experimented adding the following code to both the app and the extension i.e. using the same subsystem for both app and extension logging. let subsystem = "mySubsystem" let logger = Logger(subsystem: subsystem, category: "main") logger.info("Log from within extension") // the version in the app says Log from within app do { let logStore = try OSLogStore(scope: .currentProcessIdentifier) let oneHourAgo = logStore.position(date: Date().addingTimeInterval(-3600)) let allEntries = try logStore.getEntries(at: oneHourAgo) let filtered = allEntries .compactMap { $0 as? OSLogEntryLog } .filter { $0.subsystem == subsystem } } The filtered content only contains logging from either the app or the extension. I suppose the issue might be the use of .currentProcessIdentifier as the scope, however that's the only scope that is defined. Is what is being attempted here possible? Is there any way to write to and extract a unified log for an app and app extension? If not, how about adding it, surely this would be something useful for people to be able to do

When does a notification service extension process get terminated?
If there is the following code for a notification service extension var countOfInvocations = 0 public class NotificationService: UNNotificationServiceExtension { public override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { NSLog("Push count: \(countOfInvocations)") countOfInvocations = countOfInvocations + 1 Then if pushes are sent to the handset it can be observed in the console log that the value of countOfInvocations keeps increasing, meaning the NotificationService class is getting instantiated and destroyed within the same process. However at what point does that process get torn down by the OS? It seems to be kept alive for about 10 minutes or so. Is there a way the extension can detect its the same or a new process?

CallKit call extension invoked twice by the OS in iOS 17 beta
If you create a CallKit extension with Xcode 15 beta, then add some logging to the template code that gets created and run it on an iOS 17.3 beta phone the logging clearly shows that the OS is running the extension twice when the user turns on the extension in Settings. Run it on any device with < iOS 17 and its only invoked once, as it should be. However, not only does the OS run it twice, but based on the logging the two invocations are in parallel, not serial, suggesting two CallDirectoryHandler instances are being created and run simultaneously.

Any logging library that can enable a shared log file between the app and app extensions?
My app has several app extensions and I'd like to be able to unify the logging between them such that they write to a single shared file (which can be read from and subsequently uploaded to things like Crashltyics or Bugsnag etc.) Its possible to log directly to things like Crashlytics, however none of them I've investigated have a unified approach for the app and extensions (for example, if you use Crashlytics you have to configure the app and the extensions separately, so any logging goes to two entirely separate consoles.) Hence, instead I'm wondering if there a library that provides the ability to log to a file, and that file can be shared and simultaneously written to (in the case where the app and its extensions are running simultaneously). Do any of the existing log libraries for iOS have this ability?
