# iOS Lifecycle Workflow ## Core Sequence 1. App launch and permission strategy (camera/mic, optional share path prep). 2. SDK initialization and auth callbacks. 3. Join/start decision branch. 4. In-meeting event wiring (audio/video/chat/share/webinar where needed). 5. Background/foreground transitions and interruption recovery. 6. Leave/end and cleanup. ## Failure Domains - Expired or mismatched signature data. - Role/host-token mismatch in start flow. - App lifecycle interruption (phone call/audio route/background). - Incomplete delegate registration before meeting transitions.
