NSFileManager fileExistsAtPath in Swift 2.0?

So, using Swift 2.0, it looks like Apple are steering us towards using NSURL rather than NSString for paths.

I’m trying to ascertain whether a file exists in the user’s Documents directory in iOS, and I can’t quite piece it together.

If I use the following, Swift 2.0 complains that I shouldn’t use stringByAppendingPathComponent, and that I should use URLs.

let documents = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let dbPath = documents.stringByAppendingPathComponent(“Whatever.sqlite”)

If I then get the URL, like so:

let documentsURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
let fileURL = documentsURL.URLByAppendingPathComponent("Retrollect.sqlite”)

I then can’t call NSFileManager.defaultManager().fileExistsAtPath to ascertain whether the file exists.

Is there an equivalent of fileExistsAtPath() for an NSURL, to look inside the user’s Documents directory?

Swift 4 version:

FileManager.default.fileExists(atPath: url.path)

Never mind, one of those "five seconds later" answers.

I can use fileExistsAtPath(theURL.path) to do this. Checking that the path is non-nil first, of course!
