Problem Description
Location-based notifications added with UNLocationNotificationTrigger and CLCircularRegion do not fire consistently when the user enters the monitored region. Sometimes they work, sometimes they do not. In tests where the user physically enters the region and waits several days, the notification often never triggers.
What we’ve confirmed
Notification permission is granted
Location permission is set to “Always”
The notification request is successfully added (no error from UNUserNotificationCenter.add)
Pending notification requests are present when checked with getPendingNotificationRequests
CLLocationManager didEnterRegion / didExitRegion work when we monitor the same region via startMonitoring(for:)
UNLocationNotificationTrigger behavior is inconsistent and unreliable in our tests
Reproduction Steps
Launch the app and grant notification permission and “Always” location permission
Add a region notification (either by current GPS location or by selecting a point from MKLocalSearch)
Leave the monitored region
Later, physically return into the region
Expected: a notification is delivered when entering the region
Actual: the notification often does not appear, even after waiting days
Our Hypothesis: Coordinate System Mismatch in China
We suspect the issue may be related to coordinate systems in mainland China.
In China, Apple MapKit and MKLocalSearch use GCJ-02 (the “Mars” coordinate system required by local regulations).
Device GPS and CLCircularRegion / Core Location use WGS-84.
If an app supplies GCJ-02 coordinates to CLCircularRegion (e.g. from MapKit or search), the region center may be offset by hundreds of meters from the actual WGS-84 position. That could make the system’s “inside region” check fail, even when the user is physically inside the intended area.
Questions for Apple
Does CLCircularRegion (and therefore UNLocationNotificationTrigger) expect coordinates in WGS-84? If so, should apps in China convert GCJ-02 to WGS-84 before passing coordinates to CLCircularRegion?
Is there any official guidance or documentation for handling coordinate systems when using location-based notifications in mainland China?
Are there known limitations or special requirements for UNLocationNotificationTrigger in China (e.g. coordinate system, accuracy, or system behavior) that could explain intermittent or missing triggers?

有一个用户反馈7月8日充值了3笔后一直无法发起新的购买,总是提示已经购买。我们查了是之前的交易无法结束,我们使用StoreKit2,已经调用await transaction.finish()成功结束交易了,但是每次发起新支付时,Transaction.unfinished还会返回之前已完成的交易信息。
是设备或AppleID的问题么?用户尝试了重启设备、重新登录AppleID都没用。有什么办法解决呢?
用户无法结束的苹果交易id为:200002703899379、200002703900716、200002703902023。
A user reported that after making 3 purchases on July 8th, they have been unable to initiate new purchases, always receiving a prompt that the item has already been purchased. Upon investigation, we found that the previous transactions couldn't be finalized. We use StoreKit2 and have successfully called await transaction.finish() to end the transactions. However, every time a new payment is initiated, Transaction.unfinished still returns information about the previously completed transactions.
Could this be an issue with the device or Apple ID? The user has tried restarting the device and re-logging into their Apple ID, but these attempts were unsuccessful. Is there any way to resolve this?
The Apple transaction IDs that the user is unable to finalize are: 200002703899379, 200002703900716, 200002703902023.
Transaction can not finish in OS26.2 TestFlight
I’ve observed several areas in iOS where user experience could be enhanced, such as keyboard flexibility, animation speed, biometric options, cache management, background uploads, navigation reliability, and automation features.
Addressing these aspects would not only improve usability but also align iOS more closely with diverse user needs across regions and use cases. What enhancements would you consider most valuable?

I am trying to upgrade my app to use Xcode 26 and I cannot get my tests to launch.
I am trying to launch tests to the simulator, and I always get this error after 300 second timeout:
"encountered an error (The test runner hung before establishing connection.)"
There are no other errors getting logged.
I can run to the same simulator just fine, and in Xcode 16 the tests launch with no issues.
The tests also run fine on an actual iPhone.
Thanks in advance.
We are currently working on a SCEP server implementation that operates in FIPS-approved mode. In this mode, RSA PKCS#1 v1.5 encryption is disallowed due to compliance requirements, and only FIPS-approved padding schemes such as RSA-OAEP are permitted.
However, we have observed that the SCEP client functionality on Apple devices currently does not support RSA-OAEP for CMS EnvelopedData decryption. This creates a challenge for us in ensuring FIPS compliance while maintaining compatibility with Apple devices during certificate enrollment through SCEP.
We would appreciate your guidance on the following:
Are there any alternative FIPS-approved encryption algorithms or configurations supported by Apple devices for SCEP CMS EnvelopedData decryption?
Is there any plan or timeline for future support of RSA-OAEP on Apple platforms for this use case?

Hi all,
I'm developing fitness app and I use healthkit to track user's "STEPS" count and "Heart Rate" from their iphone devices.
I have been receiving this rejection and can't seem to get past this:
Guideline 2.5.1 - Performance - Software Requirements
The app uses the HealthKit or CareKit APIs but does not clearly identify the HealthKit and CareKit functionality in the app's user interface.
Apps using these APIs should be clearly indicated to provide transparency and valuable information to users.
Next Steps
To resolve this issue, it would appropriate to clearly identify the HealthKit and CareKit functionality in the app's user interface.
Resources
Learn more about software requirements in guideline 2.5.1.
How I tried to Resolve the Issue
I have modified my app: adding user permission prompt, adding healthkit notification, adding healthkit indicator in the UI
**1. Added a "Permission Primer" Screen (Pre-Alert) **
When a user taps "Connect Apple Health," they are now shown a dedicated explanation screen before the system permission prompt appears. This screen clearly states: "[App] integrates with HealthKit to read your Heart Rate and Steps... to calculate physical exertion." (Please see the "Connect" flow in the Session Detail view).
**2. Added Explicit Source Attribution **
I have added a permanent text label reading "Health data sourced from Apple Health" directly below the heart rate and steps statistics on the Session Detail dashboard. This ensures that users always identify the source of the displayed metrics.
3. Deployment Target Correction
I identified a configuration error where the Deployment Target was set to a future OS version. I have corrected this to the currently shipping iOS 18 to ensure full compliance with software requirements.
4. App Description Update
I have updated the App Store description to explicitly mention the HealthKit integration and its specific purpose (tracking match intensity).
However doing the above, I still continue to receive the same review message. When I asked the reviewer what else could be done to satisfy the requirement, I only get boiler plate message above. Anyone know what they really looking for?
Any insights is appreciated. Thanks!
90809: Deprecated API Usage. New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview).
I did not actively use UIWebView in my app, but this error occurred during the build upload process. This version has an additional integration of the iOS Ayla SDK and Public-9.0.7 SDK compared to the previous version. If there is indeed a call in a third-party SDK, how can I determine where the call exists? Thank you
Recently, I've noticed that background Bluetooth scanning stops when I move an app to the background on an iPhone 17 device with Bluetooth 6. I'm curious about a solution. Background Bluetooth scanning doesn't stop on devices older than iOS 26, or on devices that were updated from an iPhone 17 or earlier to iOS 26.
Some hacked my itunes connect or not sure any one tried to hack via remote desktop or else.
Hacker transferred my apps to his account, how can I get those apps back?
When I start a Simulator (iPhone 13 mini) with iOS 26 and activate "Use the Same Keyboard Language as macOS", it still sets the keyboard to US (my Mac keyboard is in German). This makes the Mac keyboard unusable. It looks like a bug, because it clearly ignores the settings. When I type “@”, I get “¬”. Restarting the simulator did nothing, changing the settings back and forth also.
BTW: Why does every single update of XCode come with a bug nowadays? I always have to spend half a day after an update to fix a problem I didn't have before. Highly frustrating.
When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?
Hello,
I am currently process of migrating an app from Team A to Team B and attempting to generate transfer identifiers using the migration endpoint:
POST https://appleid.apple.com/auth/usermigrationinfo.
Content-Type: application/x-www-form-urlencoded
However, I am consistently receiving an
{
"error": "access_denied"
} response.
[Current Configuration]
Team A (Source):
Primary App ID: com.example.primary
Grouped App IDs:
com.example.service (Services ID for Web)
com.example.app (App ID for iOS - The one being transferred)
All identifiers are under the same App Group.
Team B (Destination):
New App ID and Key created.
[Steps Taken]
Created a Client Secret (JWT) using Team A's Key ID and Team ID.
The sub (subject) in the JWT is set to the Primary App ID of Team A.
Requesting with client_id (Primary App ID), client_secret (JWT), and user_token.
[Questions]
1. App Group Impact: Does the fact that the App being transferred is a Grouped App ID (not the Primary) affect the usermigrationinfo request? Should I use the Primary App ID or the specific Grouped App ID as the client_id?
2. Ungrouping Safety: If I need to ungroup the App ID from the Primary App ID to resolve this:
Will existing users still be able to sign in without issues?
Is there any risk of changing the sub (user identifier) that the app receives from Apple?
Will this cause any immediate service interruption for the live app?
Any insights on why access_denied occurs in this Primary-Grouped configuration would be greatly appreciated.
I'm testing app transferring, before, I have migrate user from teamA to teamB, including subA->transferSub->subB process, now I'm transfer the app from teamB to teamC, after the transfer requested, I can't get transfer_id by /usermigrationinfo api, which response 400 invalid request.
the question is I can still get transfer sub by the auth/token api(grant_type: authorization_code) with teamB parameters(teamIdB/clientIdB/appSecretB/redirectUrlB/subB),but the value is same as first time transfer_id which get during teamA to teamB.
when use parameters above with target(teamIdC) to request /usermigrationinfo, invalid request was responsed.
im sure that all parameters is correct, dose it cause by teamB still in 60-days first transferring(sure already accepted)?
For our research study, it is essential that the app can advertise BLE packets even when the app is no longer in the foreground (for example, when it is in the app switcher / recents state).
Is it supported to advertise BLE packets while the app is in the background or recents state?
If so, what are the specific requirements or limitations we should be aware of (background modes, payload size, timing, etc.)?
Are there any constraints that would prevent consistent BLE advertising for research use cases?
You can't transfer this app because of the following reasons:
App Transfers Disabled for This Account
Due to irregular activity associated with your account, you cannot transfer or receive apps at this time. If you think this is an error, contact Developer Support.

Hello,
I am currently developing an iOS application using SensorKit. I encountered an issue when attempting to fetch SensorKit data in the background using background tasks (appRefresh, processing). The following error occurs:
In the delegate function func sensorReader(_ reader: SRSensorReader, fetching fetchRequest: SRFetchRequest, failedWithError error: any Error) {}, I receive the error:
SRErrorDataInaccessible.
In code specific manner:
start and handle background fetch (appRefresh)
func handleAppRefreshTask(task: BGAppRefreshTask) {
logger.logWithServer(level: .default, message: "background fetch start", category: String(describing: BackgroundTaskManager.self))
scheduleBackgroundFetch()
let queue = OperationQueue()
queue.maxConcurrentOperationCount = 1
let fetchOperation = FetchOperation()
queue.addOperation(fetchOperation)
task.expirationHandler = {
self.logger.logWithServer(level: .error, message: "background fetch expirated", category: String(describing: BackgroundTaskManager.self))
queue.cancelAllOperations()
}
fetchOperation.completionBlock = {
task.setTaskCompleted(success: !fetchOperation.isCancelled)
}
}
Background fetch operation class
class FetchOperation: Operation {
override func main() {
guard !isCancelled else { return }
Task {
// this function will execute fetch request for all user allowed sensorReader, 'func fetch(_ request: SRFetchRequest)'
await SensorkitManager.shared.startFetchAndUpload()
}
}
}
I have the following questions:
Is it possible to fetch SensorKit data in the background?
If it is possible, why does the above error occur?
If it is possible, could you provide the solution code and the correct workflow to avoid this error?
Thank you.
Hi there,
How can I best understand the changes on the eSIM Installation wizard, i.e. on iOS 18 and later after an eSIM installation you used to get steps such as labeling the eSIM, deciding what to use for iMessage & FaceTime, what to use for mobile data, main voice line, etc.
Whereas on iOS 26 you are not prompted for these steps.
