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.

We (at the NYC MTA) are building a new subway/bus app and diving deep into location tracking on iOS. We’re encountering an issue with how Core Location functions in the subway, specifically regarding how long it takes to update a passenger’s location as they travel from station to station.
As an example, please see this video: https://drive.google.com/file/d/1yaddkjyPEETvTEmClPAJ2wks8b-_whqB/view?usp=sharing
The red dot is set manually (via a tap gesture) and represents the ground truth of where the phone actually is at that moment. The most critical moment to observe is when the train physically arrives at a station (i.e., when I can see the platform outside my window). At this moment, I update the red dot to the center of the station on the map. Similarly, I adjust the red dot when the train departs a station, placing it just outside the station in the direction of travel.
The trip shown is from Rector St to 14 St. All times are in EST.
I’d like to investigate this issue further since providing a seamless underground location experience is crucial for customers. As a point of comparison, Android phones exhibit near-perfect behavior, proving that this is technically feasible. We want to ensure the iOS experience is just as smooth.
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.

I'm using react native with expo, firebase for auth, and I have google, facebook and Apple Sign In enabled. On my IOS simulator I can sign in using all 3 with no problems, but when I build and submit to test flight and test on a real device only google sign in works
It crashes when I try to sign in with facebook and I get an error saying The operation couldn't be completed. (com.apple.AuthenticationServices.AuthorizationError error 1000.)

Please allow me to confirm the Server Notifications V2 specification.
I am aware that if withdrawal an Apple account that has a subscription, the subscription will eventually be cancelled.
Regarding Server Notifications V2 notifications with a notificationType of EXPIRED, am I correct in thinking that they will be sent when the subscription expires even if the Apple account is withdrawal?
To receive server notifications from the App Store, follow the instructions in Enabling App Store Server Notifications. If your server doesn’t receive any notifications, check your server logs for any incoming web request issues, and
confirm that your server supports the Transport Layer Security (TLS) 1.2 protocol or later. If you implement version 2 of App Store Server Notifications, call the Get Notification History endpoint. If there is an issue sending a notification, the endpoint returns the error the App Store received from your server.
If your issue persists, submit a Feedback Assistant report with the following information:
The bundleId or appAppleId of your app
The date and time your issue occurred
The raw HTTP body of your notification
The affected transactionId(s) if applicable
The version of App Store Server Notifications (i.e., Version 1 or Version 2)
The environment (i.e., Production or Sandbox)
To submit the report, perform these steps:
Log into Feedback Assistant.
Click on the Compose icon to create a new report.
Select the Developer Tools & Resources topic.
In the sheet that appears:
Enter a title for your report.
Select “App Store Server Notifications” from the “Which area are you seeing an issue with?” pop-up menu.
Select “Incorrect/Unexpected Behavior” from the “What type of feedback are you reporting?” pop-up menu.
Enter a description of your issue.
Add the information gathered above to the sheet.
Submit your report.
After filing your report, please respond in your existing Developer Forums post with the Feedback Assistant ID. Use your Feedback Assistant ID to check for updates or resolutions. For more information, see Understanding feedback status.

I have been working on adding a badge number count to my app, but have run into a really weird edge case. If I have a badge number on my app, delete the application and then re-install it, the badge number still persists on the app icon until I first open the app. I tried looking to see if there is a lifecycle method that is triggered upon uninstalling an app as well as if there is a specific userDefaults attribute to check in order to clear the badge, but I can't find any clear solutions. Does anyone know of a fix to this issue?

I am testing the subscription flow in my iOS app. Initially, everything was working fine when following the official StoreKit and sandbox testing documentation. After a successful subscription, the “You’re all set” popup always displayed the environment as “sandbox.” However, after some changes, possibly upgrading macOS to the latest version, upgrading Xcode, or regenerating certificates, I can no longer connect to the sandbox testing environment. The subscription success popup now always shows the environment as “xcode.”
By default, the iOS app should run in the sandbox on macOS, so I didn’t set the “Enable App Sandbox” option to “Yes” in the Xcode build settings. When I try enabling it, Xcode throws the following error:
“Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.n3J0tr/extracted/Payload/XXXX.app : 0xe8008015 (A valid provisioning profile for this executable was not found.) Please ensure that your app is signed by a valid provisioning profile.”
Additionally, if “Enable App Sandbox” is set to “No,” the app installs successfully on a real device, but there is no prompt to trust an untrusted developer certificate, which usually appears for such certificates.
I’m not sure if this information will be useful to others, but I’ve been stuck on this issue for a while, and it’s preventing me from moving forward with my work. Any help to resolve this would be greatly appreciated. Thank you!

Hello,
I have been testing my app in iOS 18 device and while creating a server with TCP, then apple make a request for local network permission automatically. If we don't allow the permission, the connection not working. We are getting the connection timeout error even after allowing again from device setting.
Has something changed in the flow for iOS 18 version? Can someone help me to solve this issue?
I am wondering wether iOS allow apps to detect users' proxy.

Hello. Recently, the users of our APP have reported using our products, and they can normally receive push in Hong Kong. However, when traveling to Japan or some countries and regions in Europe, push will not be received.
we checked that
-the cert is valid
-the server get 'sent successfully' response
-used pushtry to test the cert and token and it can receive push in app
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?

I am trying to test using Testflight and have set up a test with a user on an account I also own which is different to me developer account. The app I believe is running in production on a separate device and is working from a user point of view, however I am not able to query the data via the console. As I said I know the user id and password as tey are mine so even when I use the Act as user service it logs in but the query is empty. I'm assuming I'm not doing anything wrong its possibly an security issue that is preventing me accessing this account. My question to the group then is how do I verify the data that is being tested?
Hello,
I'm creating an app that stores multiple Date objects: the users selects a date and a time and receives a notification at this time precisely.
The problem that happens is after saving a Date, if the device's timezone changes, the Date also changes - and that is not what's I'm expecting (just want the original time as is without depending on timezone).
I have inspected the TimeZone properties when I'm building the Date from DateComponents but nothing has worked.
Thank you for your answer.
When I try to promote schema to production, I get following error:
Cannot promote schema with empty type 'workspace', please delete the record type before attempting to migrate the schema again
However, in hierarchical root record sharing, I think it should be completely legit use case where there is empty root record (in my case workspace) to which other records reference through ->parent reference.
Am I missing something? Is this weird constraint imposed on CloudKit?
Hello Apple Developers,
I’m developing an iOS app that requires access to the user’s contacts. I understand that starting from iOS 14, Apple introduced two levels of contact permissions:
1️⃣ Full Access – The app can read all contacts.
2️⃣ Limited Access – The app can only access contacts selected by the user.
My Question:
If a user initially grants Limited Access, is it allowed by Apple’s guidelines to request Full Access later?
🔹 I understand that re-requesting permission immediately after the user denies it is against Apple’s policies.
🔹 However, if the user has already granted Limited Access, and we first show an explanation modal explaining why Full Access is beneficial, can we then prompt them to change their settings via openAppSettings()?
🔹 Alternatively, can we use Permission.contacts.request() again to re-prompt the user for Full Access, or will iOS prevent the permission prompt from appearing again?
How We Handle This in the App:
1️⃣ If a user selects Limited Access, we respect their choice and only access their selected contacts.
2️⃣ Later, if Full Access is necessary for an enhanced experience, we display a clear explanation modal explaining why the app needs Full Access.
3️⃣ If the user agrees, we attempt to guide them to openAppSettings(), allowing them to manually change the permission.
4️⃣ However, if Permission.contacts.request() can be used to directly request Full Access again, we would like to know if this is acceptable.
We want to ensure that our implementation follows Apple’s privacy guidelines while providing the best user experience.
Any official guidance or best practices on this matter would be greatly appreciated.
Thank you in advance!
Hi,
I'm trying to setup PIR service for live caller id lookup (in python but based on swift example: https://github.com/apple/live-caller-id-lookup-example). The swift example provides utilities for database setup and encryption, but I can't find any specification about which key is used for database encryption and how the ios system knows about this key in order to be able to construct the PIR requests.
So my question is how does the PIR service communicate the secret key to ios system or vice versa? (specific to the test environment, before onboarding)
My question is simple, I do not have much experience in writing swift code, I am only doing it to create a small executable that I can call from my python application which completes Subcription Management.
I was hoping someone with more experience could point out my flaws along with giving me tips on how to verify that the check is working for my applicaiton. Any inight is appreciated, thank you.

Hi Apple Team,
we reiceved the following message.
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.
Our web service sends token-based push notifications directly to the Apple Push server.
For testing: https://api.development.push.apple.com:443
In production: https://api.push.apple.com:443
We have never installed any certificates for using APNs.
Do we need to take any action regarding this message, or can we ignore it?
