permissions-registration

To register your iOS app with Meta AI and request camera access, you must start the SDK registration, handle the URL scheme callback, observe the asynchronous registration state stream, and then invoke the camera permission request API.

The URL scheme callback flow for Meta AI app registration requires intercepting the onOpenURL event in your iOS app to handle the Meta AI callback, allowing the SDK to complete the registration process asynchronously.

Yes, you can use Developer Mode for always-allowed registration, such as setting MetaAppID to 0, bypassing the release-channel requirements enforced for production environments.

To handle camera permission availability when devices disconnect, you must observe the async state streams to manage multi-device availability behavior and detect when permissions granted on linked glasses become unavailable.

Checking permission status fails before registration is complete because the SDK requires the asynchronous registration state stream to reach the registered state before permission APIs like checkPermissionStatus and requestPermission can function.

The best way to observe the iOS SDK registration state stream for Meta AI integration is to listen to the asynchronous registrationStateStream provided by the SDK, waiting until the state becomes registered before proceeding.
