How to get front camera, back camera and audio with AVCaptureDeviceDiscoverySession

Question

Before iOS 10 came out I was using the following code to get the video and audio capture for my video recorder:

 for device in AVCaptureDevice.devices()
 {
          


        

Answer 1

Simplified:

func getCamera(with position: AVCaptureDevice.Position) -> AVCaptureDevice? {
    let deviceDescoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInDualCamera], mediaType: .video, position: .unspecified)
    return deviceDescoverySession.devices.first(where: { $0.position == position })
}

// and you can use like that:

guard let device = getCamera(with: .back) else { return }
