[swift-users] Why can't we get `URL` equal on the same path?

In your opinion, `baseURL` is a factor more important than `path`. I can not unaccept your answer. But I want to know why? Is there a standard on URL equality?

As you can see, `URL` is not equal but the `path` is. I wonder why urls do not equal here?
let url = URL(fileURLWithPath: "foo/bar", isDirectory: false)let baseURL = url.deletingLastPathComponent()let newURL = URL(fileURLWithPath: "bar", isDirectory: false, relativeTo: baseURL)
print(url == newURL) // prints falseprint(url.path == newURL.path) // prints true
Here's one reason:    print(url.baseURL == newURL.baseURL)  // prints false
