这是一个创建于 2016 天前的主题，其中的信息可能已经有所发展或是发生改变。
之前写了一个注册快捷键(写死在代码里)的 mac 工具，用来调用 AppleScript，实在不熟悉 swift，所以后来写了一个 Electronjs 版本的。
但是，但是，但是 mac 升级到 10.14 后，nodejs 里调用 AppleScript 变得非常慢！会有 2~3 秒的延迟，泪目。
今天尝试了一下 swift 版本，貌似延迟小了很多，但是我不懂如何实现像 nodejs 那样加载一个配置文件，然后在代码里动态注册好所有快捷键。
google 了很久，都是些如何注册快捷键的问题。
swift 大神，看了我的代码之后，劳烦指引个方向。
