问题描述
在 Swift 3 中，访问控制的区别究竟是什么
In Swift 3, what exactly is the difference in access control between
private class Foo { }
和
fileprivate class Bar { }
假设两者都是顶级类，也就是说，它们被直接放置在一个文件中而不是嵌套在其他一些结构中?
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 private 唯一不同的地方是在类、结构或协议中.
There is no difference in your case. The only time that fileprivate differs from private is inside a class, struct, or protocol.
