How to get front camera, back camera and audio with AVCaptureDeviceDiscoverySession
You can get the front camera with the following:
AVCaptureDevice.default(.builtInWideAngleCamera, for: AVMediaType.video, position: .front)
The back camera:
AVCaptureDevice.default(.builtInWideAngleCamera, for: AVMediaType.video, position: .back)
And the microphone:
AVCaptureDevice.default(.builtInMicrophone, for: AVMediaType.audio, position: .unspecified)
Here's my code (Swift 3) to get camera position :
// Find a camera with the specified AVCaptureDevicePosition, returning nil if one is not foundfunc cameraWithPosition(_ position: AVCaptureDevicePosition) -> AVCaptureDevice?{ if let deviceDescoverySession = AVCaptureDeviceDiscoverySession.init(deviceTypes: [AVCaptureDeviceType.builtInWideAngleCamera], mediaType: AVMediaTypeVideo, position: AVCaptureDevicePosition.unspecified) { for device in deviceDescoverySession.devices { if device.position == position { return device } } } return nil}
If you want, you can also get the new devicesTypes from iPhone 7+ (dual camera) by changing the deviceTypes array.

Swift 4, iOS 10+ and Xcode 10.1 replaces
if let cameraID = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front)?.localizedName { //cameraID = "Front Camera"}
with AVCaptureDevice.DiscoverySession implementation
if let cameraID = AVCaptureDevice.DiscoverySession.init(deviceTypes: [AVCaptureDevice.DeviceType.builtInWideAngleCamera], mediaType: .video, position: .front).devices.first?.localizedName{ //cameraID = "Front Camera"}
Need to wrap it with #available(iOS 10,*) check.
