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

Swift 3

For selecting the back camera:(also you can change .back as needed)

For selecting another deviceType simple add it inside the [ ] (i.e:

[deviceTypeCamera, AVCaptureDeviceType.builtInMicrophone]

(or create a private let... like I did in the code with the back camera)

 private let position = AVCaptureDevicePosition.back
 private let deviceTypeBackCamera = AVCaptureDeviceType.builtInWideAngleCamera

 private func selectCaptureDevice() -> AVCaptureDevice? {
    return AVCaptureDeviceDiscoverySession(deviceTypes: [deviceTypeBackCamera], mediaType: AVMediaTypeVideo, position: position).devices.first

 }
