Delegate function has beed changed. Now it is

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])

And You can get information from info dictionary as following

info[UIImagePickerController.InfoKey.mediaType]

and

info[UIImagePickerController.InfoKey.editedImage]

Hope this helps.

Replace Your

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo Info: [String: Any]) {}

with

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {}

You are getting the error because of changes in Swift 4.2 version.

Use this code:

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    picker.dismiss(animated: true)
    if let originalImage = info[.originalImage] as? UIImage {
        print(originalImage)
    }
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    picker.dismiss(animated: true)
}
