We are developing a health app that relies on HKObserverQuery and BackgroundDelivery to monitor Heart Rate data. On watchOS 10.6 and 11.6 , these data updates are typically delivered reliably every 8–12 minutes, occasionally exceeding 12 minutes, but generally not longer than 15 minutes. This frequency has been sufficient for the real-time data requirements of our app.
However, after adapting our app to watchOS 26, we noticed that HKObserverQuery triggers much less frequently, with longer and very inconsistent intervals. This issue has had a major impact on our product: data collection for essential features is unreliable, resulting in a greatly diminished user experience on watchOS 26 and making the app essentially useless from the user’s perspective.
Observed Behavior:
HKObserverQuery and BackgroundDelivery are extremely unstable, with trigger intervals frequently exceeding 15 minutes, and sometimes even 20 minutes.
When the user is sedentary, intervals become even longer; there are cases where no heart rate or active energy updates are delivered for 30 minutes, or even over 1 hour.
Request for Support and Guidance:
Have there been any changes to the HKObserverQuery background delivery mechanism on watchOS 26, specifically for Heart Rate and Active Energy data?
If these changes are intentional system optimizations, could you provide guidance or recommended practices to ensure our app can reliably retrieve updates and maintain a smooth experience for users?
Thank you for your support.

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!
I double-click it, and it doesn't install. I drag it to the provisioning profile folder, and it gets deleted immediately. It's an Apple Developer problem. I've already wiped my Mac clean twice and reinstalled everything, and I'm still having this problem.

Hello Apple Developer Community,
I'm developing a cross-platform app using Flutter and the flutter_beacon library to handle iBeacon detection on iOS. My goal is to wake up the app in the background when it's in a killed/terminated state upon entering/exiting beacon regions, allowing for BLE communication (e.g., ranging or connecting to beacons). I've configured the necessary Info.plist keys for always location access and background location modes, and it works partially for single regions, but I have some specific questions/issues regarding reliability and limitations:
Background Execution Time After Wake-Up: When the app is woken in the background by a region monitoring event (enter/exit) from a killed state, approximately how much time (in seconds) does iOS allocate for the app to run before suspending it again? Is this sufficient for performing BLE operations like ranging beacons or establishing a short connection, or are there stricter limits in terminated wake-ups compared to standard background modes?
Monitoring Multiple iBeacons with Unique Identifiers: I need to monitor multiple iBeacon devices, each with potentially different UUIDs, majors, and minors. Can I add and monitor up to 20 regions simultaneously, each with a unique string identifier? If multiple beacons (from different regions) enter their respective ranges at around the same time, will the app receive separate callbacks for each region/identifier, or is there coalescing/prioritization that might cause only the last-added identifier to trigger notifications/events?
Reliability in Killed State: In a fully killed state (e.g., force-quit via app switcher), does iOS reliably relaunch the app in the background for region monitoring events? Are there any known caveats, such as requiring specific hardware (e.g., iPhone models with certain Bluetooth chips) or iOS versions (targeting iOS 14+), and how does this interact with Flutter's background execution handling via the flutter_beacon library?
After upgrading to a new iPhone and restoring from an iCloud backup using the same Apple ID, I noticed an issue with Health app permissions.
■ What is happening
On my previous iPhone, an app had permission to read step count data.
After restoring to the new iPhone, the app still appears in the Health app under Sources.
However, when I tap the app, the usual data type permission toggles (such as Steps) are not displayed at all.
As a result, the app is unable to read step count data.
■ Additional details
The app itself seems to be recognized as a Health data source.
However, the data type permission screen is empty.
No ON/OFF switches are shown.
The backup was created on iOS 18, and the restore was performed on iOS 26.
I have not yet confirmed whether this also happens with other iOS version combinations.
■ Questions
Is it expected behavior that Health app permissions (per data type) are not restored via iCloud backup?
Has anyone experienced a similar situation where the app appears under Sources but the permission options are missing? If so, how did you resolve it?
Any information from users who have experienced the same issue would be greatly appreciated.
