AVCaptureSession's startRunning method is thread blocking and seems to be slow. What is this method doing behind the scenes?
For context: I'm working on Simulator Camera support and I have a 'fake' AVCaptureDevice that might be causing this. My hypothesis is that AVCaptureSession tries to connect to the device and waits for a notification to be posted back.
I'd love to find a way to let my fake device message AVCaptureSession that it's connected.
