Additional Details:

• Permissions and Security:

  • The extension inherits permissions for camera and photos access from your application.
  • It is designed with a focus on security and privacy, ensuring that the device remains locked and secure while capturing content.
  • If permissions are not granted, the system will request device unlock and launch the app instead of the extension.

• User Experience:

  • The extension must show a camera viewfinder immediately upon launch, or it will be terminated by the system.
  • Users can capture photos or videos using hardware buttons, providing a quick point-and-shoot experience.

• Data Handling:

  • Captured content can be saved directly to the photo library using Photokit, even when the device is locked.
  • The extension cannot use network resources or access shared group containers while the device is locked.

• Transition to App:

  • For actions requiring more privileges, the extension can request to open the parent application, prompting the user to unlock the device.
