我想在我的 Mac OS 项目 （Swift UI） 中添加一个 Package dependency Package，但我只能添加一个 Package Collection，我不能只添加一个单独的包依赖包，我想添加 mysql kit 以使我的项目链接到 Mysql 数据库
Xcode adds the package URL
To add a package outside of a package collection, you can enter the git URL into the search bar of the UI for adding packages, or for local packages that are on disk already, there's a button labeled Add Local.
