I typed out the script and was told to change NSFileManager to FileManager. But once I changed it it told me it cannot call value of non-function type 'FileManager'
let urls = FileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

3,234 PointsBecause you mentioned you had to change NSFileManager to FileManager I'm guessing you're using Swift 3. Apple made some serious changes to the language and the code of this course is not Swift 3 (or not yet, they will update). For your code, this should work:
lazy var applicationDocumentsDirectory: URL = { let urls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask) return urls[(urls.endIndex - 1)] }()
Chances are high that you have to update every piece of code of this course to Swift 3 manually. You can do this in the meantime while taking the course, it won't be fun.
You can also download the project-files, open them with Xcode 8 (which I'm guessing you're working with) and let Xcode converting them for you to Swift 3.
