Replace AVCaptureStillImageOutput by AVCapturePhotoOutput in swift - ios

Question

In my code, Xcode say AVCaptureStillImageOutput is deprecated but I don't know how to change by AVCapturePhotoOutput.
I know that the var output is the problem and the one who I had to replace.
Thanks for your help.
class CameraView: UIViewController,UIImagePickerControllerDelegate{
var session: AVCaptureSession?
var input: AVCaptureDeviceInput?
var output: AVCaptureStillImageOutput?
var previewLayer: AVCaptureVideoPreviewLayer?
override func viewDidLoad() {
super.viewDidLoad()
//Initialize session an output variables this is necessary
session = AVCaptureSession()
session?.sessionPreset = AVCaptureSession.Preset.photo;
output = AVCaptureStillImageOutput()
let camera = getDevice(position: .back)
do {
input = try AVCaptureDeviceInput(device: camera!)
} catch let error as NSError {
print(error)
input = nil
}
if(session?.canAddInput(input!) == true){
session?.addInput(input!)
output?.outputSettings = [AVVideoCodecKey : AVVideoCodecType.jpeg]
if(session?.canAddOutput(output!) == true){
session?.addOutput(output!)
previewLayer = AVCaptureVideoPreviewLayer(session: session!)
previewLayer?.connection?.videoOrientation = AVCaptureVideoOrientation.portrait
previewLayer?.frame = self.view.bounds
previewLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill;
cameraView.layer.addSublayer(previewLayer!)
session?.startRunning()
}
}
//Select library photo
}
//Get the device (Front or Back)
func getDevice(position: AVCaptureDevice.Position) -> AVCaptureDevice? {
let devices: NSArray = AVCaptureDevice.devices() as NSArray;
for de in devices {
let deviceConverted = de as! AVCaptureDevice
if(deviceConverted.position == position){
return deviceConverted
}
}
return nil
}
