私有和文件私有顶级类之间的区别 [英] Distinction between private and fileprivate top-level classes

问题描述

在Swift 3中，访问控制的确切区别是

In Swift 3, what exactly is the difference in access control between

private class Foo { }

和

fileprivate class Bar { }

假设这两个都是顶级类，也就是说，它们直接放在一个文件而不是嵌套在其他结构中？

assuming both are top-level classes, that is, they are placed directly into a file rather than nested in some other construct?

推荐答案

您的情况没有区别。 fileprivate 与不同的唯一时间是在类，结构或协议内部。

There is no difference in your case. The only time that fileprivate differs from private is inside a class, struct, or protocol.
