试图将聊天客户端从swift 4传递到swift 4.2并且使用选择器我发现了麻烦.

UIImagePickerControllerEditedImage // 无法使用索引类型为"UIImagePickerController.InfoKey"的类型'[String:Any]'下标

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

    if let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage {
        self.userProfileImage.contentMode = .scaleAspectFit
        self.userProfileImage.image = pickedImage
    }

    picker.dismiss(animated: true, completion: nil)
}
