Swift:需要类前缀吗? [英] Swift: Class Prefix Needed?

问题描述

我应该按照推荐答案

否，

No, you do not need class prefixes in Swift, because classes are namespaced to the module in which they live.

如果您需要区分(例如)Swift中的Array和应用程序中声明的Array类/结构，可以通过将其键入为Swift.Array或MyProject.Array.也可以使用扩展名:

If you need to disambiguate between (for example) an Array from Swift and an Array class/struct that you've declared in your app, you can do so by typing it as a Swift.Array or a MyProject.Array. That works with extensions as well:

extension Swift.Array {
    ...
}

extension MyProject.Array {
    ...
}
