Detailed software architecture guide for mobile developers synchronizing iOS HealthKit data with hospital FHIR endpoints.
iOS restricts background execution time. Applications must utilize HKObserverQuery and HKAnchoredObjectQuery to efficiently sync only new and modified records without draining device battery.
As Apple and Google introduce new health data types with each OS release, the integration bridge must feature dynamic schema mapping to prevent app crashes on unrecognized data types.
All health payloads must be encrypted with AES-256-GCM on the mobile device before transmission, utilizing TLS 1.3 with certificate pinning to prevent man-in-the-middle attacks.
