FYI for anyone building HealthKit apps across iOS and watchOS:
If you’re testing on iOS 26.4 beta 2 / watchOS 26.4 beta 2 and seeing HealthKit syncing issues between iPhone and Apple Watch, it’s not your code.
The problem appears to come from the current beta.
On stable releases, HealthKit syncing works normally.
Save yourself the debugging time. 🫡
