Thanks for your reply. I tried the initial modification shown in the video to select the default camera as external camera. if let externalCamera = AVCaptureDevice.default(.external, for: .video, position: .unspecified) { defaultVideoDevice = externalCamera print("External camera selected") } else if let dualCameraDevice = AVCaptureDevice.default(.builtInDualCamera, for: .video, position: .back) { defaultVideoDevice = dualCameraDevice } Test setup details: I am testing on my iPad Pro 11" 4 Gen running iPadOS 17 (public beta). I use Xcode 15 beta 4 to use the iPad as the run destination (wireless mode). An external USB webcam is connected to the iPad during the test. This camera is working when I test using the FaceTime app. However, I see the below error on app start. Capture session runtime error: related decl 'e' for AVError(_nsError: Error Domain=AVFoundationErrorDomain Code=-11819 "Cannot Complete Action" UserInfo={NSLocalizedDescription=Cannot Complete Action, NSLocalizedRecoverySuggestion=Try again later.}) Error Code = AVError(rawValue: -11819) Did you do any additional modifications in the project for your tests? Thanks!
