For any Swift lovers, coming to this question trying to check if a file is a directory here you go:

///
/// Check if NSURL is a directory
///
internal func fileIsDir(fileURL: NSURL) -> Bool {
    var isDir: ObjCBool = false;
    fileManager.fileExistsAtPath(fileURL.path!, isDirectory: &isDir)
    return Bool(isDir);
}

///
/// Check if a path is a directory
///
internal func fileIsDir(path: String) -> Bool {
    var isDir: ObjCBool = false;
    fileManager.fileExistsAtPath(path, isDirectory: &isDir)
    return Bool(isDir);
}

(Note that I tried doing return isDir as Bool but it didn't work. But the above Bool initiation seems to work.)
