Problem with UIImagePickerController swift - ios

Question

Im working in an application which requires the camera. The way Im opening it is this:
let Picker = UIImagePickerController()
Picker.delegate = self
Picker.sourceType = .camera
present(Picker, animated: true, completion: nil)
Everything works perfectly, this is the result which I get:
What I would like to do now is replace that "Cancel" button for a button which let the user select a photo from his photolibrary. I have been reading a lot but I still do not get a solution.
Thank to everyone

You can do it instead of that
#IBAction func buttonOnClick(_ sender: UIButton)
{
let alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: { _ in
self.openCamera()
}))
alert.addAction(UIAlertAction(title: "Gallery", style: .default, handler: { _ in
self.openGallary()
}))
alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))
/*If you want work actionsheet on ipad
then you have to use popoverPresentationController to present the actionsheet,
otherwise app will crash on iPad */
switch UIDevice.current.userInterfaceIdiom {
case .pad:
alert.popoverPresentationController?.sourceView = sender
alert.popoverPresentationController?.sourceRect = sender.bounds
alert.popoverPresentationController?.permittedArrowDirections = .up
default:
break
}
self.present(alert, animated: true, completion: nil)
}
func openCamera()
{
if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.camera))
{
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}
else
{
let alert = UIAlertController(title: "Warning", message: "You don't have camera", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}
func openGallary()
{
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
imagePicker.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)
}

Make sure you are doing this 2 things:
Specifying the content type you are looking for:
Picker.mediaTypes = [KUTTypeImage as String, KUTTypeMovie as String], for example to select both videos and images.
That you added in your info.plist the camera permission description Privacy - Camera Usage Description
