Permissions & Registration (iOS)

Register your app with Meta AI, then request the device permissions it needs.

The DAT SDK separates two concepts:

1. Registration — Your app registers with Meta AI to become a permitted integration
2. Device permissions — After registration, request specific device permissions (e.g., camera)

All permission grants occur through the Meta AI companion app.

Registration flow

Start registration

func startRegistration() async throws {
    try await Wearables.shared.startRegistration()
}

This opens the Meta AI app where the user approves your app. Meta AI then calls back via your URL scheme.

Handle the callback

.onOpenURL { url in
    Task {
        _ = try? await Wearables.shared.handleUrl(url)
    }
}

Observe registration state

Task {
    for await state in Wearables.shared.registrationStateStream() {
        switch state {
        case .registered:
            // App is registered, can request permissions
        case .unavailable:
            // Registration is unavailable
        case .available:
            // Ready to register
        case .registering:
            // Registration in progress
        }
    }
}

Unregister

func startUnregistration() async throws {
    try await Wearables.shared.startUnregistration()
}

Camera permissions

Check permission status

let status = try await Wearables.shared.checkPermissionStatus(.camera)

Request permission

let status = try await Wearables.shared.requestPermission(.camera)

The SDK opens Meta AI for the user to grant access. Users can choose:

• Allow once — temporary, single-session grant
• Allow always — persistent grant

Multi-device behavior

Users can link multiple glasses to Meta AI. The SDK handles this transparently:

• Permission granted on any linked device means your app has access
• You don't need to track which device has permissions
• If all devices disconnect, permissions become unavailable

Developer Mode vs Production

For production, get your APPLICATION_ID from the Wearables Developer Center.

Prerequisites

• Registration requires an internet connection
• Meta AI companion app must be installed
• For Developer Mode: enable in Meta AI > Settings > Your glasses > Developer Mode
