Я работаю над приложением, которому нужно AVCameraCalibrationData. Мое приложение аварийно завершает работу, и из-за исключения.
AVCaptureDataOutputSynchronizer initWithDataOutputs:] Unsupported AVCaptureOutput in dataOutputs - <AVCapturePhotoOutput: 0x283d6ab80>'
Я пробовал другие обходные пути, но depthDataOutput не вызывается. Пожалуйста, посмотрите на мою камеру configuration. Любая помощь будет высоко ценится.
