FYI for anyone building HealthKit apps across iOS and watchOS:

If you’re seeing iPhone/Apple Watch HealthKit sync issues on iOS 26.4 beta 2 / watchOS 26.4 beta 2, it’s the beta, not your code.

Stable releases sync fine.

Save yourself the debugging time. 🫡

如果你使用 HKWorkoutRouteBuilder 让 Fitness 写GPS 数据，这里的地图不显示, 一定要注意这句话：
try to keep the time between locations to 3 seconds or less.
