You are right Jens. If I use `appendingPathComponent`, it works. let url = URL(fileURLWithPath: "foo/bar", isDirectory: false)
let baseURL = url.deletingLastPathComponent() let newURL = URL(fileURLWithPath: "bar", isDirectory: false, relativeTo: baseURL) let testURL = baseURL.appendingPathComponent("bar") print(url == newURL) // prints false print(url.path == newURL.path) // prints true print(url == testURL) // prints true print(url.path == testURL.path) // prints true Zhaoxin On Sat, Oct 15, 2016 at 11:19 AM, Jens Alfke <j...@mooseyard.com> wrote: > > > On Oct 14, 2016, at 5:16 PM, zh ao via swift-users < > swift-users@swift.org> wrote: > > > > In your opinion, `baseURL` is a factor more important than `path`.
