I have an odd issue I'm trying to troubleshoot. I have an app that is deployed to our enterprise and works on almost all of our devices.
Lately, I have devices (very small number) where the app installs from our MDM and it crashes upon launch, it does not get past the launch screen. If I remove and reinstall the app from the MDM it still crashes.
I decided to put the devices in developer mode and if I run the App from Xcode on the device it works fine. If I stop it and run it right from the device it also works.
If I do a final build of the app and install it using "Devices and Simulators", the app crashes upon launch.
Using "Devices and Simulators" I check for crash log for the app and no file.
I am stumped as to whats going on.

Activity
I have start new live activity with push notifications,but sometimes this code"activity.pushTokenUpdates" can not callback to me,so I can't update the activity with push notifications. And I already click “Allow” button in my live activity widget.How can I solve this problem.
Here are my code:
fileprivate func observeLiveActivityForRemoteCreate() {
// obverser pushToStartToken
Task {
if #available(iOS 17.2, *) {
var beforeToken = ""
for await pushToken in Activity<HLPlatformActivityAttributes>.pushToStartTokenUpdates {
let pushTokenStr = pushToken.map{String(format: "%02.2hhx", arguments: [$0])}.joined()
// avoid send duplication
if beforeToken == pushTokenStr {
return
}
beforeToken = pushTokenStr
// send pushToStartToken to service
await HLPlatformLiveActivityBridge.registerLiveActivity(withAttributesName: self.activityAttributesName, pushToStartToken: pushToken, seq: seqCreate(), pushType: .jPush)
}
}else {
// Fallback on eralier versions
}
// obverser live activity update
Task {
for await activity in Activity<HLPlatformActivityAttributes>.activityUpdates {
if let businessLiveActivityId = activity.attributes.businessLiveActivityId, let liveActivityId = activity.attributes.liveActivityId {
Task {
var beforeToken = ""
for await pushToken in activity.pushTokenUpdates {
// here the problem:sometimes pushToken not update to me
let pushTokenStr = pushToken.map{String(format: "%02.2hhx", arguments: [$0])}.joined()
// avoid send duplication
if beforeToken == pushTokenStr {
return
}
beforeToken = pushTokenStr
// send pushToken to service
}
}
Task {
for await stateUpdate in activity.activityStateUpdates {
if stateUpdate == .active {
// live activity create
}
}
}
}
}
}
}
Our app provides a calendar that integrates with the default calendar app. Specifically, we use iOS EventKit to perform CRUD operations on calendar data.
Recently, we have received reports from users that all of their events have disappeared. However, after reviewing our implementation and logs, we have not been able to identify the cause. Some users have also reported that all data in their default calendar app has disappeared as well.
Does anyone have any idea what might be causing this?
To delete an event within our app, users must press the delete button and then confirm the deletion in a dialog. Additionally, it is not possible to delete more than two events at once.
We've seen many people in the community discussing a bug where calendar events disappear after updating to iOS 18. If you have any information about when or why this happens, we'd appreciate it if you could share your insights.
Hi Apple Support,
I am encountering an issue while testing in-app purchases in the sandbox environment.
I have created a sandbox tester account
Logged out of the App Store and System Settings on my Mac.
My main developer account is signed in under Sign In & Capabilities in Xcode.
The Bundle ID matches the one configured in App Store Connect.
The Product ID I am querying also matches the configuration.
Deleting the app and reinstalling.
Restarting my Mac.
When running my code in debug mode, I observe the following:
Running debug build
App Store environment: Production
[1b294b55] Error updating Storefront: Error Domain=StoreKit_Shared.StoreKitInternalError Code=7 "(null)"
Valid products: []
Invalid product IDs: ["com.x.x.x.monthly"]
No products found
The Product ID (com.x.x.x.monthly) matches the one I have configured in App Store Connect.
The bundle id matches.
When I create a StoreKit Configuration file in Xcode and sync it with my app, I can see the product IDs correctly.
Below are the relevant code snippets for fetching and handling products:
func fetchProducts() {
guard !productIDs.isEmpty else {
print("No product IDs configured")
return
}
let request = SKProductsRequest(productIdentifiers: productIDs)
request.delegate = self
print("Starting product request...")
request.start()
}
func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
DispatchQueue.main.async {
print("Valid products: \(response.products)")
print("Invalid product IDs: \(response.invalidProductIdentifiers)")
self.products = response.products
if self.products.isEmpty {
print("No products found")
} else {
print("products not empty")
for product in self.products {
print("Fetched product: \(product.localizedTitle) - \(product.priceLocale.currencySymbol ?? "")\(product.price)")
}
}
}
}
func debugStoreSetup() {
if let receiptURL = Bundle.main.appStoreReceiptURL {
if receiptURL.lastPathComponent == "sandboxReceipt" {
print("App Store environment: Sandbox")
} else {
print("App Store environment: Production")
}
} else {
print("No receipt found")
}
}
Could you help identify why my app is not recognizing the Product ID in the sandbox environment?
Thank you for your assistance.
Hello,
I’m building a health-related app for both watchOS and iOS, which needs to monitor certain health data (e.g., heart rate, active energy).
Before updating to watchOS 26, the queries worked reliably without any issues. However, after adapting to watchOS 26, some users have reported that health data updates stop being delivered.
What I’ve observed:
HKObserverQuery with enableBackgroundDelivery is set up normally.
On WatchOS 26, the query sometimes stops delivering updates entirely after a certain point, and once an update is missed, it may stop delivering further updates completely.
Restarting the Apple Watch temporarily restores delivery, but the problem reoccurs after some time.
This makes background health data monitoring unreliable for my app.
Here’s a simplified version of the code we are using:
guard let heartType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return }
let query = HKObserverQuery(sampleType: heartType, predicate: nil) { query, completionHandler, error in
if let error = error {
logEvent("Observer error: \(error.localizedDescription)")
return
}
logEvent("Heart rate changed")
MyNotificationManager.shared.sendNotification() // Send a local notification
completionHandler()
}
healthStore.execute(query)
healthStore.enableBackgroundDelivery(for: heartType, frequency: .hourly) { success, error in
if success {
logEvent("Background heart rate delivery enabled")
} else {
logEvent("Failed to enable background heart rate delivery: \(error?.localizedDescription ?? "Unknown error")")
}
}
Could you please clarify:
Is this a known issue with HKObserverQuery and enableBackgroundDelivery on watchOS 26?
Are there any recommended workarounds or best practices to ensure continuous background delivery of health data?
Thank you in advance for your help.

I have added an "App Intents Extension" target to my main application in macOS. This generated the below two files:
TWAppIntent.swift
import AppIntents
struct TWAppIntent: AppIntent {
static var title: LocalizedStringResource = "TWAppIntentExtension"
static var parameterSummary: some ParameterSummary {
Summary("Get information on \(\.$TWType)")
}
//launch app on running action
static var openAppWhenRun: Bool = true
// we can have multiple parameter of diff types
@Parameter(title: "TWType")
var TWType: String
func perform() async throws -> some IntentResult & ReturnsValue<String> & ProvidesDialog {
return .result(value: TWType, dialog: "Logged break.")
}
}
TWAppIntentExtension.swift
import AppIntents
@main
struct TWAppIntentExtension: AppIntentsExtension {
}
I m able to build the extension target and I my intent action is available in the shortcuts app. However, on launching a shortcut with the above created intent action. I m getting the below popups:
I have identified what is causing this error. Setting the openAppWhenRun to true is causing this error. I don't get this when it is set to false. This property is supposed to launch the application, but can someone help me understand why is it happening? This is only causing the error when using this property for AppIntent Extension and not for In app handling for the AppIntent.
Can we not launch our application from AppIntent extension?
Hello developers,
We're facing a critical issue with our app and need your insights:
Since today, 3 specific IAP products return empty data when calling Product.products(for: [productId]).
This affects all users, preventing any successful purchases of these items.
Other IAP products seem unaffected.
let products = try await Product.products(for: [productId])
Key details:
Production environment
Issue started: 2025.6.17
No recent app updates
All products show as "Approved" in App Store Connect
Questions:
Has anyone experienced similar issues recently?
Could this be a StoreKit or App Store system problem?
Any suggestions for diagnosing or resolving this, besides contacting Apple Support?
Recommendations for temporary workarounds?
This is severely impacting our business. Any help is greatly appreciated!
Thank you!
I'm reaching out to see if anyone else is experiencing issues with the Live Caller ID feature on iOS. We recently encountered a problem where the feature stopped working entirely.
Here's a brief overview of the situation:
We were monitoring test traffic on our backend and noticed everything came to a halt around 1:00 AM UTC on November 15th.
After this time, any attempts to reach our backend through calls failed completely.
I tested this across multiple devices running iOS 18.2 and iOS 18.0.
I used both TestFlight builds and development builds via Xcode, which should communicate directly with our backend.
I experienced the problem on our main application as well as a dedicated test app.
To troubleshoot further, I even set up a local server on localhost and tried directing requests there, but the requests did not reach the local server when a call was received.
Further debugging in Console.app revealed the following error:
identity request returned error: Error Domain=com.apple.CipherML Code=400 "Error Domain=com.apple.CipherML Code=401 "Unable to request data by keywords batch: failed to fetch token issuer directory"
However, when I manually tried to hit our server endpoint using curl, the request successfully reached the server:
curl https://our_server/something
hb_method=GET hb_uri=/something [Hummingbird] Request -- log on backend
This suggests that while our backend is responsive, the requests from the iOS client side are simply not being initiated.
Excited for AlarmKit! I have found two concerns that I cannot find answers for though.
The volume of my alarms seems to be very quite relative to the full volume capability of the device. For example, if I turn the volume all the way up and play the audio file, the sound is very loud. However then, if I set the alarm using alarm kit with the same audio, the track played during the alerting phase is not that loud. I am afraid that it will not be loud enough in real life. Will there be future support to set the volume level of the alarm to maximum settings?
When I press the volume buttons (with the app open) during an active alarm, the audio stops, but the alarm manager does not clear these events. The alarm manager does clear the alarm event if the alarm is stopped through a live activity.

I am pretty sure iOS 13.4 (beta and later) did support Coded PHY (Long Range). Tested devices are iPhone SE2 and iPhone 11 Pro.
However, it seems iOS 14 removed the support of Coded PHY, accidentally or on purpose, I don't know?
The same PHY update request returns "1M PHY" in iOS 14, but "Coded PHY" in iOS 13 (13.4 beta and later).
Anyone knows why?

I recently encountered an issue with Xcode 16.2 while attempting to integrate Settings.bundle into a new app. I added Settings.bundle as a new file (using the provided template), but when I ran the app (the default "Hello World" project), the expected three default controls (Name, Enabled, Slider) did not appear in the app's settings.
To troubleshoot, I downgraded my system to macOS Sonoma 14.7.2 and Xcode 15.4 (on a 2023 Mac Mini, M2). After this downgrade, everything worked as expected. With a new project, adding Settings.bundle, and running the app, the settings entry for the app appeared, including the three default fields.
This behavior suggests a potential issue or incompatibility with Xcode 16.2.
Hello,
I use Storekit2 to test the purchase of subscription products. After purchasing a subscription product in the sandbox, it will automatically renew 12 times, and then it will no longer automatically renew. When I click to purchase again, calling the
try await product.purchase()
method does not pop up the purchase pop-up window. In fact, it will directly go to the
case let .success(.verified(transaction)):
step, and the
Transaction.currentEntitlements is empty
For years our iOS apps have experienced a networking problem, which blocks them connecting to our servers via their API endpoint domains.
How can we recover after the scenario described below?
Using 3rd party error logging solutions, which have different endpoint domains, we can record the error:
NSUnderlyingError": Error Domain=kCFErrorDomainCFNetwork Code=-1200 "(null)" UserInfo={_kCFStreamPropertySSLClientCertificateState=0, _kCFNetworkCFStreamSSLErrorOriginalValue=-9816, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9816, _NSURLErrorNWPathKey=satisfied (Path is satisfied), viable, interface: pdp_ip0[lte], ipv4, dns, expensive, uses cell}, "_NSURLErrorFailingURLSessionTaskErrorKey": LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308>, "_kCFStreamErrorDomainKey": 3, "_NSURLErrorRelatedURLSessionTaskErrorKey": <__NSSingleObjectArrayI 0x301f82e60>(
LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308>
)
"NSLocalizedDescription": An SSL error has occurred and a secure connection to the server cannot be made., "NSLocalizedRecoverySuggestion": Would you like to connect to the server anyway?
-9816 is the "server closed session with no notification" error based on comments in CoreFoundation source files. Subsequent API endpoint calls to the same domain return the same error.
The SSL error occurs most prevalently after a server outage. However, despite our best efforts, we have been unable to replicate triggering the problem for development purposes via experiments with our server.
When the error occurs the users report that:
Fully closing (i.e. not just sending to background) and reopening the app does NOT clear connectivity to our server being blocked.
Problem seems more prevalent when using mobile/cell data.
Switching from mobile/cell data to WIFI resolves the connection problem and then switching back to mobile/cell data shows the problem again. So the underlying problem is not cleared.
All other apps on the same device and mobile/cell data or WIFI connection, like Safari, have no problems connecting to the Internet.
Deleting and reinstalling, or updating (when an update is available) resolves the problem.
Or after waiting a few days the problem seems to resolve itself.
The last two point above suggest that something is persisted/cached in the app preventing it from connecting properly with subsequent network attempts.
Notes:
We have one shared instance of the URLSession in the app for its networking because we are aware of the perils of multiple URLSession instances.
We recently added conditions to call the URLSession await reset() method when detecting the SLL errors before repeating the request. It is debatable whether this reduces the problem as we still see logged cases with the subsequent requests hitting the same -9816 error.
URLSession configuration:
let config = URLSessionConfiguration.default
config.timeoutIntervalForResource = 22
config.timeoutIntervalForRequest = 20
config.requestCachePolicy = .reloadIgnoringLocalCacheData
config.urlCache = nil
when I go to software and update it says can’t check for updateS.

I have an iPhone 14 Pro. I downloaded the iOS 26 beta and had a SERIOUS error, rendering the phone unusable.
I charged it to 60% and kept it plugged in while updating.
While updating, I restarted several times at the Apple logo, then at the Welcome screen, and it had quite a few bugs with low battery warnings.
When I turned it on, I noticed I had 1% (I thought it was strange).
When it was plugged in, it wouldn't charge; it only had 1% left, and it also restarted every 2 minutes. Off-plugged, it did exactly the same thing.
In the end, I had to go back to iOS 18.5; I had no problems with this version.
I have a strange crash which I have problems understanding. It only happens on a few devices, after a ModelContainer migration, and it doesn't seem to crash on the migration itself.
The fetch is done in onAppear, and shouldn't necessarily result in a crash, as it is an optional try:
let request = FetchDescriptor<Rifle>()
let data = try? modelContext.fetch(request)
if let data, !data.isEmpty {
rifle = data.first(where: { $0.uuid.uuidString == settings.selectedRifleId }) ?? data.first!
}
When I get logs from users, there seems to be an error in encoding?

Hi,
I'm working with the new FSKit framework and have successfully implemented a custom file system using FSUnaryFileSystem. Mounting the file system via Terminal works perfectly — I can create, delete, and browse files and directories as expected.
Since /Volumes is protected on modern macOS systems, I cannot mount my file system there directly. Instead, I mount it into a different writable directory (e.g., /tmp/MyFS) and then create a symbolic link to it in a user-visible location such as ~/Downloads/MyFS.
Finder does see the symlink and displays it with a "Volume" icon, but clicking it results in an error — it cannot be opened. It seems like Finder does not treat the symlinked mount as a fully functional volume.
Is there a proper way to register or announce a FSKit-mounted file system so that Finder lists it as a real volume and allows access to it? Are there additional steps (APIs, notifications, entitlements, or Info.plist keys) required to integrate with Finder?
Any insight would be greatly appreciated.
Thanks!
I have added a Network Extension to my iOS project to use the WireGuard library. Everything was working fine up to Xcode 16, but after updating, I’m facing a build issue.
The build fails with the following error:
No such file or directory: '@rpath/WireGuardNetworkExtensioniOS.debug.dylib'
I haven’t explicitly added any .dylib to my project. The Network Extension target builds and runs fine on Xcode 16.
Hi everyone
In the last 24 hours, I’ve been running into some issues with the CloudKit console.
Most of the time, I‘ll get an error stating an error has caused this web page to stop working correctly. Reloading doesn’t fix the issue, nor does using different browsers:
Today I’ve got another error, something along the lines of the Console not being able to fetch the teams I’m assigned to and an XHF error pop-up.
Has anyone encountered the same issues? After trying multiple times, I’m able to reach my database but it’s a bit frustrating as it’s very unreliable this way.
Thanks for your feedback!
Dave
