AVCaptureVideoPreviewLayer iOS Simulator crash Swift 3

Question

AVCaptureVideoPreviewLayer crashes when running on simulator now.

Not possible to set the session.

var session: AVCaptureSession? {
    get{
        return (self.layer as! AVCaptureVideoPreviewLayer).session
    }
    set(session) {
        (self.layer as! AVCaptureVideoPreviewLayer).session = session
    }
}

Try running your application on an actual device instead of simulator. The AVCaptureVideoPreviewLayer session cannot be captured on simulator.

It works on the actual device. But it is sometimes convenient to have it running on the simulator. It worked on the previous Xcode. – WYS Oct 05 '16 at 11:57

Fix the crash here by checking like

 if let captureDevice = AVCaptureDevice.default(for: AVMediaType.video) {
    // init AVCaptureSession here
 }
