Updated Evdzhan's answer for Swift 4.0:

    FileManager.default.fileExists(atPath: fileURL.path!, isDirectory: &isDir)
    return isDir.boolValue
}

//
// Check if a path is a directory

func fileIsDir(path: String) -> Bool {
    var isDir: ObjCBool = false;
    FileManager.default.fileExists(atPath: path, isDirectory: &isDir)
    return isDir.boolValue
}
