Hello! What is the TTL for evaluation key(s) used in Live Caller ID feature on iOS client side? We would like to align our server-side key storage TTL with the iOS client implementation to optimize memory usage.
Would really appreciate your help on this.

The application is developed with Xamarin Framework and it is live now.
The customer installed the app and purchased the annual subscription.
And for some reason, they uninstall and reinstall the application on the same device.
Now user wants to restore the subscription. In the application, there is an option to Restore the subscription. But restore API not return purchase details.
But when clicking the subscription button instead of restoring the subscription, it says you subscribed to this plan".
is there any possibility of not getting VerifyRecipt even after a successful purchase?

DESCRIPTION OF PROBLEM
We have developed an app and server based on the WireGuard protocol. While we have successfully implemented device-wide VPN, we are now working on enabling per-app VPN functionality.
The per-app VPN payload is successfully delivered, and the designated app can read the configuration and establish a connection to the VPN server. However, we are experiencing extremely slow download data rates, measuring only in bytes.
Steps Taken:
Created an app-layer payload.
Configured NETestAppMapping in the app’s Info.plist, using the VPNUUID defined in the payload for the Chrome app.
Despite these configurations, data transfer remains significantly slow. We would appreciate any insights into potential causes or recommendations to resolve this performance issue.
Thank you for your assistance.
How can NEPacketTunnelProvider launch the companion application, or notify user to launch the application?
I have built an iOS VPN that uses credentials stored in the keychain, and it works as expected. Now I'm trying to add OAuth login support.
Everything works fine at first. I login from the companion application, store tokens in the keychain, then launch the VPN from either System Settings or the companion application.
However, when the OAuth refresh tokens expire, or the OAuth IdP otherwise requires login, I can't perform the OAuth login from the NEPacketTunnelProvider. Login must happen from the companion application, which likely isn't running. I need the NEPacketTunnelProvider to either launch the companion application directly or to notify the user to do so.
Searching and reading docs yields:
You can't perform OAuth login from within the NEPacketTunnelProvider because it requires user interaction
There is no way to guarantee that the companion application is running on iOS (otherwise one would use NEVPNStatusDidChange)
You can't launch the companion application from NEPacketTunnelProvider using a custom URL because of security concerns
You might be able to launch the companion application from a system extension...
Some sources say you still can't guarantee that the system extension is loaded whenever the NEPacketTunnelProvider needs it anyway.
Of course, any of these conclusions could be wrong.
At this point I'm not sure where to begin. Is there another approach that could be initiated by the NEPacketTunnelProvider (push notifications, system notifications, smoke signals)?
Any help would be appreciated.
Thanks,
Bill Welch

Hey, I was wondering on how to react to the focus mode being turned off inside the FocusFilterIntent. I've successfully managed to call a specific action when the focus is being set, but I now want to deactivate/ react when the focus is being deactivated. How can I achieve something like this?
I am currently using StoreKit2 to set up the in-app purchase subscription flow, and I have already configured the subscription products in App Connect. I created a StoreKit Configuration file in Xcode and used it in the scheme. However, after completing the purchase, the transaction.jsonRepresentation data returns a transactionId of 0. After checking the documentation, I found that I need to disable the StoreKit Configuration and enable Sandbox Testing. But after disabling the StoreKit Configuration, I can't retrieve the real product data using Product.products(for: productIds). I can confirm that the ProductId I provided is real and matches the data configured in App Connect. Could you please help me identify the issue?
When I quit the app from the background task list, CLLocationUpdate.liveUpdates does not resume properly and start location updates. However, if I kill the app directly, it can recover and start location updates.

Is it possible to integrate a button in an app that displays advertisements to support charities -without offering any direct reward to the user?
I have an app that pairs with a wearable Bluetooth device that collects users' health data. My web backend sends two push notifications every hour to all app users—one at XX:05 and another at XX:15. The first notification instructs the app to download data from the paired wearable device, while the second prompts the app to upload the downloaded data to the backend server's database.
However, I’ve noticed that many push notifications are not processed by iOS apps, especially at night. Based on Apple's documentation, iOS prioritizes push notifications and may ignore lower-priority ones to conserve battery life.
Is there a way to increase the priority to ensure that more (or all) push notifications are processed?
Would integrating the HealthKit framework help? Currently, I use Firebase Cloud Messaging (FCM) to send push notifications. Additionally, my app falls under the Health & Fitness category. Would changing it to Medical increase priority? P.S. I understand that Apple requires certain certifications for an app to be classified as Medical.

I am working on watch os project. I need to check network connectivity when user turn on and off the network.
I am using NWPathMonitor for check network availability. I am connected with wifi but it still showing unsatisfied not real device but it's working perfect on simulator.
yesterday my Xcode app worked, I upgraded my Xcode and simulator today, but now i suddenly get:

When are you guys going to fix the CarPlay issues with this new update? I use this for work and it’s really an issue. Nothing is working and it takes up entirely too much space.
I have an issue that causes multiple instances of the push provider to be initialized. And I'd like to ask you what could trigger the instantiation NEAppPushProvider subclass. It seems like it's being triggered excessively. If there's documentation that I have overlooked then just show it to me and I'll be on my way.
Here's the details. But really all I want to know is why is my subclass for NEAppPushProvider keeps getting initialized. If you can answer me that than maybe all these details don't really matter but here they are.
Here's why I believe there's multiple push provider. I see logs for my push provider initializing but I don't see it de-initializing. I also see redundant logs showing multiple instances trying to log into my server. Each time it initializes, an additional log is added for trying to log into my server.
In the app, the system saves it's configuration shortly after initialization, after saving and loading the push configuration, the app doesn't touch config.
Meanwhile in the extension, after 8 or so hours, the extension starts creating a new instance of the push provider. Then a few hours later it does it again. And again. Until the watch dog kills us for wasting too much CPU.
Normally on a fresh install, I'll observe turning off the wifi to call stop on the push provider and later have the push provider de-initialize.
The extension maintains a socket connection to the server, the server can send it messages to display push notifications. The software runs on hospital networks, which will not have access to the internet. It seems like the connection to the server is stable from the logs. I don't detect any disconnections. I'll check with the server to confirm.
In the app I call removeFromPreferences to clear out any extensions before logging in/saving push configurations. And I call saveToPreferences on the NEAppPushManager. I do this to make sure I don't have more than one push configuration saved at one time. I also have many logs looking out for this. I used the sample code from apple as the basis of the my own Push Manager. I can post code if you deem it necessary.
Hope to here from you soon. Thank you.
Hey,
I would love to access the users Contact (ie. the Me Card)
Apple recently released the Invites app and within this app you can find the users Contacts Photo. I tried to replicate this behaviour but I currently need to match based on a name or email or something else. I have no idea how to receive this data because when using the Invites app I only remember the app asking for Contacts permission and nothing else so far.
let store = CNContactStore()
let keysToFetch = [CNContactImageDataAvailableKey, CNContactImageDataKey, CNContactThumbnailImageDataKey] as [CNKeyDescriptor]
let email = "test@test.de"
let predicate = CNContact.predicateForContacts(matchingEmailAddress: email)
do {
let contacts = try store.unifiedContacts(matching: predicate, keysToFetch: keysToFetch)
let imageDatas: [Data] = contacts.compactMap { $0.imageData }
self.images = imageDatas.map { UIImage(data: $0) ?? UIImage() }
} catch {
print("Error fetching contacts: \(error)")
}
This is how I am retrieving the Image. MAYBE someone can help me out.
Thank you so far

The easiest way to explain this is to show it. On any device, open Maps, set it to Driving (which will show traffic). Go to Baltimore Maryland. In the water just south east of the city there is a bridge (Francis Scott Key Bridge). . On Apple Maps the road is colored dark red.
At certain zoom levels, there is a "button" (red circle with a white - in it). When you click on that "button", it says 1 Advisory (Road Closed).
How do I show this "button" on my map. My map shows the dark red color, but no "button" appears.
The only "advisory" that I've been able to find is when you create a route. Of course you can't create a route over a road that fell into the water.
struct ContentView: View {
@State private var position = MapCameraPosition.region(
MKCoordinateRegion(
center: CLLocationCoordinate2D(latitude: 39.22742855118304, longitude: -76.52228412310761),
span: MKCoordinateSpan(latitudeDelta: 0.05407607689684113, longitudeDelta: 0.04606660133347873)
)
)
var body: some View {
Map(position: $position)
.mapStyle(.standard(pointsOfInterest: .all, showsTraffic: true))
.cornerRadius(25)
}
}
Is this a WCDWAD, or is there a way to show the "button"

Hi.
I am facing a panic in distributed virtual filesystem of my own making.
The panic arises on attempt of copying a large folder, or writing a large file (both around 20gb).
An important note here is that the amount of files we try to copy is larger than available space (for testing purposes, the virtual file system had a capacity of 18 gigabytes).
The panic arises somewhere on 12-14gigabytes deep into copying. On the moment of panic, there are still several gigabytes of storage left.
The problem is present for sure for such architectures and macOS versions:
Sonoma 14.7.1 arm64e
Monterey 12.7.5 arm64e

The origin of the problem is surely inside my filesystem. However, the panic happens not there but somewhere in watchdog. As far as I can tell, the source code for watchdog is not available for public.
I can't understand what causes the panic.
Let's say we have run out of space. Couldn't write data. Writing received a proper error message and aborted. That's what is expected.
However, it is unclear for why the panic arises.
Hey there,
i implemented live activity in my app and iam trying to start the live activity from push notification, updates works fine even when the app is in background but starting the activity creating issue mostly on background and kill mode when i check the delivery of live activity on cloudkit console it says stored for device power considerations.
anyone having the same issue ?
I am able to block apps using FamilyControl and Shield. Unblocking is also simple—just assign nil to store.shield.applications. However, I want to unblock them even when the app is not open.
Use case: Let's say the app allows users to create a session where a particular app is blocked for a specific duration. Once the session starts, the app should remain blocked, and as soon as the session time ends, it should automatically be unblocked.
Please help me with this. Thank you!
So i am pretty new to Xcode, but i have been using Python and other language for some while. But I am quite new to the game of view and view control. So it may be that i have over complicated this a bit - and it may be that I have some wrong understanding of the dependencies and appcontroller (that i thought would be a good idea). So here we have a main file we call it app.swift, we have a startupmanager.swift, a appcoordinator and a dependeciescontainer. But it may be that this is either a overkill - or that I am doing it wrong.
So my thought was that i had a dependeciecontainer, a appcoordinator for the views and a startupmanager that controll the initialized fetching. I have controlled the memory when i run it - checking if it is higher, lower eg - but it was first when i did my 2 days profile i saw a lot of new errors, like this: Fikser(7291,0x204e516c0) malloc: xzm: failed to initialize deferred reclamation buffer (46). and i also get macro errors, probably from the @Query in my feedview.
So my thought was that a depencecie manager and a startupmanager was a good idea together with a app coordinator.
But maybe I am wrong - maybe this is not a good idea? Or maybe I am doing some things twice? I have added a lot of prints and debugs for checking. But it seems that it starts off to heavy?

I received an email from Apple saying that I needed to replace the APNS certificate.
I am inquiring because I am curious about who has the relevant authority and who actually makes the changes.
Could you please provide specific guidance on this?
Hello,
We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate.
To ensure a smooth transition and avoid push notification delivery failures, please make sure that both old and new server certificates are included in the Trust Store before the cut-off date for each of your application servers that connect to sandbox and production. At this time, you don’t need to update the APNs SSL provider certificates issued to you by Apple.
If you have any questions, please contact us.
