Getting alias path of file in swift

Question

I\'m having trouble resolving the alias link on mac. I\'m checking if the file is an alias and then I would want to receive the original path. Instead I\'m only getting a Fi

Here's a Swift 3 implementation, based largely on vadian's approach. My idea is to return a file URL, so I effectively combine it with fileURLWithPath. It's an NSURL class extension because I need to be able to call into it from existing Objective-C code:

extension NSURL {
    class func fileURL(path:String, resolveAlias yn:Bool) -> URL {
        let url = URL(fileURLWithPath: path)
        if !yn {
            return url
        }
        do {
            let vals = try url.resourceValues(forKeys: [.isAliasFileKey])
            if let isAlias = vals.isAliasFile {
                if isAlias {
                    let original = try URL(resolvingAliasFileAt: url)
                    return original
                }
            }
        } catch {
            return url // give up
        }
        return url // really give up
    }
}
