Reply to ‌Xcode26-built apps cannot run on iPhone 6 or earlier devices‌
Thank you for the reply, but according to the requirements on this link https://developer.apple.com/cn/app-store/submitting/, starting from April 2026, apps uploaded to App Store Connect must use iOS 26 SDK, which means Xcode 26 is also required. This seems contradictory to resolving the current issue. Could you provide the specific reason for the aforementioned problem? Why could the ipa compiled with Xcode 26 a week ago be installed, run, and used on an iPhone 6 12.5.8?

HealthKit Background Health Data Collection, Emergency Contacts, and Automated Alerting Feasibility
I have a few feasibility questions regarding health data processing on iOS, related to HealthKit and system capabilities: Background Health Data Collection Can an iOS app continuously collect and process health data in the background, including: Collecting health data from the Health app while the device is locked or in sleep mode Triggering user notifications when anomalies are detected in health data processing Are there any technical limitations? Do these capabilities require specific enterprise qualifications or additional fees? 2. Emergency Contacts Integration Can an app write or modify the system’s built-in Emergency Contacts (Medical ID)? If a user updates Emergency Contacts in iOS Settings, can the app receive a change notification or access the updated data? 3. Automated Alerting for Health Metrics Beyond Apple’s fall detection, can abnormal health metrics (heart rate, irregular rhythm, blood oxygen, etc.) trigger automated alerts such as SMS to preset emergency contacts—w

Family Controls (Distribution) approved via email but portal still shows "Submitted" - blocking App Store submission
Hi, I submitted a Family Controls (Distribution) entitlement request for my app Faith Lock (com.faithlock.ios) - a prayer-focused iOS app that uses the Screen Time API to help users block distracting apps. I received an approval email, but the portal still shows the request as Submitted and the Distribution option does not appear under Additional Capabilities for my identifier. This is blocking me from submitting to App Store Connect. Details: Bundle ID: com.faithlock.ios Team ID: F86P575UNP Request IDs: 3PWTDR8KL3 / 885ZK276KK Status in portal: Submitted (unchanged since approval email) Has anyone experienced this? Is there a way to get the portal manually updated to reflect the approval? Any help or escalation from a DTS engineer would be greatly appreciated. Thank you.

DeviceActivityMonitor intervalDidEnd not firing for non-repeating timed unlock
I’m building an iOS app that uses FamilyControls + ManagedSettings + DeviceActivity. Goal: temporarily “unlock” a shielded app for N minutes, then automatically re-apply the shield when the timer expires. What I do: In the main app, when user picks an expiry (e.g. 15 min, 30 min). I start a non-repeating DeviceActivity schedule and remove the app’s ApplicationToken from ManagedSettingsStore().shield.applications. I also store activeUnlockBundleID etc. in an App Group so the DeviceActivityMonitor extension can re-lock at the end. Expected: DeviceActivityMonitor.intervalDidEnd(for:) is invoked when the non-repeating interval ends, and I re-add the token to the shield set. Actual: The app does not re-lock when the interval expires. I added OS logs as well as “debug local notifications” from the DeviceActivityMonitor extension in: init() intervalDidStart intervalDidEnd eventDidReachThreshold None of these logs or notifications ever appear, which suggests the extension is never invoked (or cannot schedule

Left navigation bar items become invisible after rotating device and presenting detail view in split view
A user of my app, whose main view is a split view, reported an issue which causes the left navigation bar items to disappear without apparent reason if they rotate the device and later show the detail view, preventing them from using the back button to show the root view again. Am I doing something wrong or is it a bug? I can reproduce the issue with the following steps: Create a new document-based iOS app (as it uses scenes by default, as opposed to a regular app). Paste the code below. In the target build settings, delete Launch Screen Interface File Base Name and set Launch Screen (Generation) to YES. Without this step, for some reason, the issue doesn't happen. Launch the app in iPhone Simulator. Tap the top left button to show the root view, then the “detail” button to show the detail view. The left navigation bar button is still visible. Rotate the Simulator window right, then left again. Tap the top left button to show the root view, then the “detail” button to show the detail view.

App Store Version Not Working on iOS 12
I recently released version 8.5.4 (build 188) using Cloud Build. During testing via TestFlight, the app worked correctly on an iPhone 6 running iOS 12.5.8. However, after the app was published on the App Store, I found that the same version does not open at all on iOS 12 devices. Previously, earlier versions (such as 8.5.3) were functioning properly on iOS 12. My app’s minimum deployment target is set to iOS 12.0. This issue appears only with the App Store version, while the TestFlight version works fine on the same device. Due to this, I have paused the phased release of version 8.5.4 to prevent further impact on users still running iOS 12. I would like guidance on the following: 1. Has there been any recent change or limitation affecting apps targeting iOS 12 on the App Store? 2. Is there a way to prevent iOS 12 users from downloading version 8.5.4 while allowing them to continue using version 8.5.3? 3. Is there any recommended approach to ensur

Reply to AlarmKit alarm occasionally fires at exactly 12:00 AM
Hi SeoulForest and everyone, I’m joining this thread to share additional information regarding the reported issues with AlarmKit. While I don’t have a solution yet, I have both received user reports and personally experienced the same or similar behavior. The occurrence is rare (about once a month), but it happens consistently enough to be a reliability concern for an alarm-based feature. My Implementation Context: I have implemented a system that schedules approximately 60 fixed-schedule alarms. The Issue: Alarms occasionally fail to trigger at the scheduled time. Comparison: I set Local Notifications using the exact same date objects. These notifications arrive perfectly on time, which confirms there are no errors in the date/time logic itself. Observed Behaviors: Delayed Triggers: Alarms sometimes fire several minutes late, or in some cases, not at all for a long period. Midnight Firing: I have observed instances where an alarm that failed to trigger at its scheduled time would suddenly fire around midnigh

How to recreate Apple Music mini player transition in SwiftUI
Hello, I am building an audio player app in SwiftUI and trying to recreate the behavior of Apple Music's mini player and full player. I'm struggling to get the animation to seamlessly transition between the mini player and the full player. Currently, it feels disconnected and doesn't resemble the smooth animation seen in Apple Music. What I want to achieve: Full player that expands/collapses from/to the mini player Smooth artwork transition between both states Drag down to collapse the full player Support both newer APIs like tabViewBottomAccessory and older iOS versions Questions: What is the best way to build this transition in SwiftUI? Should I use matchedGeometryEffect or something else? Should this be a custom container instead of fullScreenCover? How would you support both new and older iOS versions? What is the best way to implement drag to dismiss? Thanks for any help! Example code: struct ContentView: View { @State private var isFullPlayerPresented = false var body: some View { TabV

Reply to Choosing Minimum Deployment Targets
Would it make sense for Apple to change the default iOS 17 minimum deployment target to 17.5 since that it the newest version with a simulator available? Or is there any reason that it would make sense for Apple to release and iOS 17.6 or 17.7 simulator? Should I submit a Feedback Assistant report?

Reply to ‌Xcode26-built apps cannot run on iPhone 6 or earlier devices‌
We are experiencing similar issues on an iPad Air running iOS 12.5.8. Building with Xcode 26.4 causes our app deployment from TestFlight to crash on startup without any logs. The same app with minor code changes was built a week ago with Xcode 26.3 and deployment from TestFlight was successful on the same iPad.

I'm experiencing exactly the same issue since upgrading to iOS 26.4 with the same code, and it's also blocking Live Activities updates. I'm also having issues on tvOS 26.4, which uses CKSyncEngine.
