The feed stayed black even when the session reported running: the preview was a manually-framed sublayer (frame set in viewDidLoad/viewDidLayout, which raced the async permission callback and could end up zero-sized), and the session was configured across threads (addInput/Output on main, startRunning on a queue). Switch to the canonical AVFoundation pattern: the preview is now the view's backing layer (CameraPreviewView via layerClass), so it always fills the view with no frame bookkeeping, and all session configuration + start/stop run on a dedicated serial queue with delegate/state callbacks hopped to main.
