I am currently encountering a problem: during the process of uploading a large file, I have moved the file that was not successfully uploaded to the trash can. These two operations have been tested to be serial (triggering the 'create Item' callback first, followed by the 'modify Item' callback), which means that the file must be uploaded before it can be moved to the recycle bin (which can also result in the file being stored in the cloud recycle bin). I want to implement: directly interrupt this upload process and then do not complete the upload. How can I achieve this? Please help me. Thank you
Greetings my fellow engineers,
I use SwiftData in my iOS app. The schema is unversioned and consists of a single model. I've been modifying the model for almost two years now and relying on automatic database migrations. I had no problems for all that time, but now trying to add a property to the model or even remove a property from the model results in an error which seems like SwiftData is no longer capable of performing an automatic migration.
The log console has things like the following:
CoreData: error: NSUnderlyingError : Error Domain=NSCocoaErrorDomain Code=134190 "(null)" UserInfo={reason=Each property must have a unique renaming identifier}
CoreData: error: reason : Can't find or automatically infer mapping model for migration
CoreData: error: storeType: SQLite
CoreData: error: configuration: default
CoreData: annotation: options:
CoreData: annotation: NSMigratePersistentStoresAutomaticallyOption : 1
CoreData: annotation: NSInferMappingModelAutomaticallyOption : 1
CoreData: annotation: NSPersistentStoreRemoteChangeNotificationOptionKey : 1
CoreData: annotation: NSPersistentHistoryTrackingKey : 1
CoreData: error: <NSPersistentStoreCoordinator: 0x7547b5480>: Attempting recovery from error encountered during addPersistentStore: 0x753f8d800 Error Domain=NSCocoaErrorDomain Code=134140 "Persistent store migration failed, missing mapping model."
Have you ever encountered such an issue? What are my options?
I have an app that uses BLE to connect to access doors. Since iOS 26, when it hasn't connected to any doors for a while, it deactivates, whereas in older versions of iOS it continues to work all day without stopping. Has anyone else experienced this? I've found problems with people who have had the same issue since upgrading to the latest version of iOS 26. Is there a known issue with BLE in iOS 26? I haven't found any official information. thnks

Facing an issue with audio playback using AVPlayerViewController in iOS application. We are using the native player to play recorded audio files.
When the AVPlayerViewController appears, the native user interface is displayed correctly, including the playback controls and the volume slider.
However, when the user interacts with the volume slider
The slider UI moves and responds to touch events.
The actual audio output volume does not change. The audio continues playing at the initial volume level regardless of the slider position.
We initialize the player and present it modally using the following code:
AVPlayerViewController *avController = [[AVPlayerViewController alloc] init];
avController.player = [AVPlayer playerWithURL:videoURL];
// Setting initial volume
avController.player.volume = 1.0f;
avController.modalPresentationStyle = UIModalPresentationOverFullScreen;
avController.allowsPictureInPicturePlayback = NO;
// Present the controller
[self presentViewController:avController animated:YES completion:nil];
Hello team,
Would this mean that content filters intended for all browsing can only be implemented for managed devices using MDM? My goal would be to create a content filtering app for all users, regardless of if their device is managed/supervised.
thanks.

During Apple Pay in-app provisioning (EV_ECC_v2), our iOS app successfully obtains the issuer provisioning certificates and generates cryptographic material. The flow fails when Apple posts the card blob to Apple’s broker (card creation step), returning HTTP 500 from .../broker/v4/devices/{SEID}/cards.
Steps:
Call issuerProvisioningCertificates?encryptionVersion=EV_ECC_v2
→ 200 OK; returns ECC leaf + Apple Root CA chain; nonce=2a831be4.
2. Build {encryptedCardData, activationData, ephemeralPublicKey}
3. POST /broker/v4/devices/{SEID}/cards
Expected: 200 OK on /broker/v4/devices/{SEID}/cards, or 5xx with a descriptive error if payload/cryptography is invalid.
Observed: 500 Internal Server Error from Apple broker on /cards (labeled “eligibility” in PassKit logs), causing a terminal failure in Wallet UI.
Hi,
We design a Live Activity for our app.We find that in iOS26 system, the widget can not display the correct system display model(Light mode or dark mode), always display with dark mode. When our app run in other system ,such as iOS 17, iOS18 ,it work fine.
I find other developer had post a topic three month ago , but it seems there is not any new response about the feedback.
https://developer.apple.com/forums/thread/799684?answerId=857377022#857377022
Anyone have idea?
Thanks .
Below is my code template:
struct BroadcastLiveActivityBackgroundView: View {
@Environment(\.colorScheme) var colorScheme: ColorScheme
var body:some View {
LinearGradient(
stops: [
Gradient.Stop(color: LiveActivityColor.backgroundColors(self.colorScheme).last!, location: 0.00),

I'm encountering a strange behavior with one of my home's on Home app while I'm off network. When I launch the app it indicates that the hub is not responding and all of my devices are unavailable.
However, on the menu bar at the bottom if I switch to "Automation" and back to "Home" the pop-up goes away and my devices are accessible again (sometimes this take a few attempts). Siri is also able to consistently control my devices without an issue.
The same behavior occurs with Home app on other devices (e.g. Mac) and with other members that have access to the household. 3rd party HomeKit app like "Controller" does not have an issue.
This issue began with iOS 26 and I haven't had much luck resolving the issue. I already tried rebooting everything, including removing and re-adding an Apple TV (home hub). I have other homes shared with me in Home App with similar network/environment that are still working. The home I'm having issues has the most number of devices though (over 100+).
The One-time codes documentation details how to enable autofill for SMS based codes. However, there is no details about how to correctly implement autofill for email based codes.
I am observing the email based autofill works inconsistently when using email based OTC. In my application:
There is latency of 10-15 seconds from when the email arrives to when it is available for autofill.
After the autofill feature is used, the OTC email is not being deleted from the inbox automatically.
Without documentation, it's unclear to me what I might be doing wrong that is causing these side effects.
I found an ietf proposal for how autofill with email based codes might work, but it’s unclear if this is how Apple has implemented the feature: https://www.ietf.org/archive/id/draft-wells-origin-bound-one-time-codes-00.html#name-email
Existing docs for Autofill using SMS: https://developer.apple.com/documentation/security/enabling-autofill-for-domain-bound-sms-codes
Hello,
I’m integrating promotional offers for auto-renewable subscriptions using StoreKit 2.
The offer is displayed correctly, the Apple purchase sheet appears, and I can start the payment flow. The sheet shows the correct discounted price and the end date of the offer. However, after confirming the purchase, an alert appears saying “Unable to Purchase - Contact the developer for more information”
When dismissing the alert, Xcode logs the following:
Purchase did not return a transaction:
Error Domain=ASDServerErrorDomain Code=3902
"No se ha podido realizar la compra"
UserInfo={
NSLocalizedFailureReason=No se ha podido realizar la compra,
client-environment-type=Sandbox,
AMSServerErrorCode=3902,
storefront-country-code=ESP
}
Test environment:
App installed from Xcode on a real iPhone
Logged in with a Sandbox Apple ID
Using StoreKit 2
Promotional offer applied using:
Product.PurchaseOption.promotionalOffer(_:compactJWS:)
On the server side, I generate the promotional offer signature exactly as described in Apple’s documentation:
https://developer.apple.com/documentation/storekit/generating-a-signature-for-promotional-offers
The signature is generated using a Subscription Key
Signed with ECDSA + SHA256
Uses the correct invisible separator (U+2063)
The signature is validated locally using the derived public key and verifies correctly
The sandbox user has had previous subscriptions, which is why this promotional offer is eligible and shown.
Given that:
The offer is displayed correctly
The purchase sheet shows the discounted price and duration
The signature validates locally
The error occurs only after confirming the purchase
My question is:
Is this a known limitation or issue with promotional offers in the Sandbox environment?
Should promotional offers be tested exclusively via TestFlight instead of Sandbox?
Any clarification would be greatly appreciated.
Thank you!
Hello,
This is my first post in the forums, and I'm still learning my way with iOS Development and Swift. My apologies if the formatting is not correct, or If I'm making any mistakes.
I'm currently trying to implement an iOS App where the device needs to share the location with my server via an API call.
The use case is as follows: the server expects location updates to determine if a device is inside/outside a geofence. If the device is stationary, no locations need to be sent. If the device begins moving, regardless of whether the app is in foreground, background, or terminated, the app should resume posting locations to the server.
I've decided to use the CLLocationUpdate.liveUpdates() stream, together with CLBackgroundActivitySession().
However, I have not been able to achieve the behavior successfully. My app either maintains the blue CLActivitySession indicator active, regardless of whether the phone is stationary or not, or kills the Indicator (and the background capability) and does not restore it when moving again. Below I've attached my latest code snippet (the indicator disappears and does not come back).
// This method is called in the didFinishLaunchingWithOptions
func startLocationUpdates(precise: Bool) {
// Show the location permission pop up
requestAuthorization()
// Stop any previous sessions
stopLocationUpdates()
Task {
do {
// If we have the right authorization, we will launch the updates in the background
// using CLBackgroundActivitySession
if self.manager.authorizationStatus == .authorizedAlways {
self.backgroundActivity = true
} else {
self.backgroundActivity = false
self.backgroundSession?.invalidate()
}
// We will start collecting live location updates
for try await update in CLLocationUpdate.liveUpdates() {
// Handle deprecation
let stationary = if #available(iOS 18.0, *) {
update.stationary
} else {
update.isStationary
}
// If the update is identified as stationary, we will skip this update
// and turn off background location updates
if stationary {
self.backgroundSession?.invalidate()
continue
}
// if background activity is enabled, we restore the Background Activity Session
if backgroundActivity == true { self.backgroundSession = CLBackgroundActivitySession() }
guard let location = update.location else { continue }
// Do POST with location to server
}
} catch {
print("Could not start location updates")
}
}
}
I'm not sure why the code does not work as expected, and I believe I may be misunderstanding how the libraries Work. My understanding is that the liveUpdates stream is capable of emitting values, even if the app has gone to the background/terminated, thus why I'm trying to stop/resume the Background Activity using the "stationary" or "isStationary" attribute coming from the update.
Is the behavior I'm trying to achieve possible? If so, I'm I using the right libraries for it? Is my implementation correct? And If not, what would be the recommended approach?

I’m implementing a subscription purchase flow using promo code redemption via an external App Store URL.
Flow:
User taps “Purchase” in the app (spinner shown)
App opens the promo redemption URL (apps.apple.com/redeem)
User completes redemption in the App Store
User returns to the app
The app must determine whether the subscription was purchased within a reasonable time window
The app listens to Transaction.updates and also checks
Transaction.currentEntitlements when the app returns to the foreground.
Issue:
After redeeming a subscription promo code via the App Store and returning to the
app, the app cannot reliably determine whether the subscription was successfully
purchased within a short, user-acceptable time window.
In many cases, neither Transaction.updates nor
Transaction.currentEntitlements reflects the newly redeemed subscription
immediately after returning to the app. The entitlement may appear only after a
significant delay, or not within a 60-second timeout at all, even though the
promo code redemption succeeded.
Expected:
When the user returns to the app after completing promo code redemption,
StoreKit 2 should report the updated subscription entitlement shortly thereafter
(e.g. within a few seconds) via either Transaction.updates or
Transaction.currentEntitlements.
Below is the minimal interactor used in the sample project. The app considers
the purchase successful if either a verified transaction for the product is received via Transaction.updates, or the product appears in Transaction.currentEntitlements when the app returns to the foreground. Otherwise, the flow fails after a 60-second timeout.
Questions:
Is this entitlement propagation delay expected when redeeming promo codes through the App Store?
Is there a recommended API or flow for immediately determining whether a subscription has been successfully redeemed?
Is there a more reliable way to detect entitlement changes after promo code redemption without triggering user authentication prompts (e.g., from AppStore.sync())?

My main goal is to maximize BLE range at the moment, though eventually I would like to allow for greater throughput when updating firmware over the air as well. I understand that Coded PHY is not on the roadmap based on the support ticket I previously entered, but is there any way to force 1M PHY. Even when I request it, I get a phy renegotiation (update) of 2 PHY.
The universal links for my apps stopped working.
The server where the AASA files where hosted worked on IPV4 exclusively, a few days ago i changed the configuration to IPV6 only. I´ve created new IPV6 entries, renewed all certifactes and deleted all IPV4 entries for the domains.
All seemed fine, but at Saturday I realized that my universal links stopped working for new user.
What i´ve done to find the issue:
Example domain that was used for debugging: "https://developffw.burns.fun"
I´ve verified the AASA file is hosted properly by using different browsers and Postman to retrieve it. The file can be accessed and the certificates look fine.

I took a look at the headers from the Apple CDN network response. These indicate some sort of connection error.

Took a look at the log files of the server.
I can´t find any entry from the Apple servers neither in the default logs nor in the error log entries.
The curl attempts are logged with response code 200.
I´ve tried sudo swcutil dl -d https://developffw.burns.fun/onboard in the Terminal on my MAC.
Output:
The operation couldn´t be completed. (SWCErrorDomain error 8.)
This indicates to me threre is an issue for the Apple servers accessing my server. But I don´t know what could be the reason. There is no firewall configuration that could block the requests. And there has been no change at all besides the IPV4 / IPV6 protocol change.
This issue is the same for all the domain listed on this server.
I´v even created a new app for this purpose and created a new AASA entry and associated link. Same issue.
I´m pretty much lost here. Everything looks fine from my side. Google assetlinks.json seem to work fine.
I would really appreciate some help on how to solve this, i´m at my wits end.
From the document https://developer.apple.com/documentation/sensorkit/srfetchrequest we know that "SensorKit places a 24-hour holding period on newly recorded data before an app can access it. This gives the user an opportunity to delete any data they don’t want to share with the app. A fetch request doesn’t return any results if its time range overlaps this holding period."
Will this holding period reset each time when I called startRecording() ?
Let's say I upgrade my app to a new version, do I need to call startRecording again to init the data collection process? will it be able to query the data collected from previous version's app ?

We are developing a hybrid iOS app where Angular content is rendered inside a WKWebView, hosted by a native Swift application.
We use the GameController framework to detect whether an external Bluetooth keyboard is connected to an iPad. The following code is executed when the app enters the foreground and also when requested by the web layer:
func keyboardStatusHandler(){
let isKeyboardConnected = GCKeyboard.coalesced != nil
if(!isKeyboardConnected){
//sent status to Angular
} else {
//sent status to Angular
}
}
Crash details
We are seeing intermittent crashes on iPad with the following stack trace:

Observed scenarios
Crash occurs when the app transitions from background to foreground
Crash also occurs when the Angular layer requests keyboard status, triggering the same code path
Questions
Has anyone encountered crashes related to GCKeyboard.coalesced or GCKeyboardInput like this?
Are there known issues with the GameController framework when querying keyboard state during app lifecycle transitions?
Is there a recommended or safer way to detect external keyboard connection status on iPad (especially when using WKWebView)?
Any insights, known platform issues, or suggested workarounds would be greatly appreciated.
Thanks!
当用户开启App自动更新后,自动更新App后,App有些功能会错乱。
1.有的会触发旧App代码功能,如旧版本有个选择框,在新版本选择框从界面移除了,但自动更新看,有的用户会还会触旧版本选择框的功能
2.数据错乱,如App录入数字6,发送到服务端变成5.4
现在发现这些问题。都是要把App删除,重新下载就可以。
请问要如何避免这样的问题。
App是有Objective-C,会不会与开启 BITCODE有关?
