iOS

14.3

What's New

iOS 14.3 enhances App Clip discoverability through native code scanning and expands HealthKit air-quality support to five countries with localized recommendations. Developers must upgrade to SKAdNetwork signature v2.0 for iOS 14+ attribution postbacks, and MDM policies now restrict Web Clip targeting of Apple applications.

Highlights

Breaking Changes

  • TargetApplicationBundleIdentifier in WebClip no longer supports Apple-made apps; non-MDM devices must use Home screen shortcuts instead
  • SKAdNetwork v1.0 signatures no longer generate postbacks on iOS 14+, even with advertised app installed
