HealthKit Blood Pressure authorization broken on iOS 26.5 RC

Hello,

I'm experiencing a bug on iOS 26.5 RC1/RC2 where the Blood Pressure option is silently excluded from the HealthKit permission dialog (when requesting HKQuantityTypeIdentifierBloodPressureSystolic and HKQuantityTypeIdentifierBloodPressureDiastolic). This does not reproduce on iOS 26.4.2 or earlier.

What happens:

When BP types are requested alone, a blank white modal slides up and immediately dismisses — no permission UI is shown. When BP is requested alongside other types, a normal dialog appears for those other types, but Blood Pressure is simply absent from the list.

The completion handler returns success = YES, error = nil in both cases, but BP permission is never granted. The result:

• Settings → Privacy & Security → Health → [app] shows Blood Pressure as requested but not granted
• getRequestStatusForAuthorizationToShareTypes for the BP types keeps returning ShouldRequest indefinitely
• HealthKit queries for BP samples return no data

Workaround:

Manually toggling Blood Pressure to ON in Settings → Privacy & Security → Health → [app name] fixes everything - queries work, notifications fire, and getRequestStatusForAuthorizationToShareTypes correctly returns HKAuthorizationRequestStatusUnnecessary.

Environment:

• Confirmed broken: iOS 26.5 RC1 (23F75) and RC2 (23F77), iPhone 11; iOS 26.5 RC1 (23F73), simulator
• Confirmed working: iOS 26.4.2 (device), iOS 26.4.1 (simulator)
