For Swift 4:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    guard let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage else {
        return
    }
    ...
}

• On method parameter, change from [String: Any] to [UIImagePickerController.InfoKey : Any]
• On the picked image, change from info["UIImagePickerControllerOriginalImage"] to info[UIImagePickerController.InfoKey.originalImage]
