How do you use the function createFile?

Question

I found this declaration in Apple's API reference but I'm not sure how to use it.

func createFile(atPath path: String, contents data: Data?, attributes attr: [String : Any]? = nil) -> Bool

When I start typing createFile, there is no auto-complete that resembles this declaration either.

My path is a directory on my computer (not including the file's name), and the data is a string.

I have seen that question. It doesn't create a new file. It just writes to an existing one? Edit: Oh that is not the one I was thinking. I will try that one. — ludluck, Nov 08 '16 at 18:02

It does not work. I have successful code that writes to an existing file. I just need to create a new one. Can I not use the `createFile` function to make one? — ludluck, Nov 08 '16 at 18:13
Do you mean what I am creating? Yes it is an iPhone application. — ludluck, Nov 08 '16 at 18:17
You have to start typing `createFile` on an instance of `FileManager`. — rmaddy, Nov 08 '16 at 18:22
Note that now the `attributes` is of type `[FileAttributeKey: Any]` — Benj, Apr 25 '19 at 08:21

It works fine on my machine. You probably just aren't using a FileManager object:

You are right thank you. And I am just using the simulator. – ludluck Nov 08 '16 at 18:26
No offence to you or professionals, but can I just not play around? – ludluck Nov 08 '16 at 18:31
@matt did you try it? I am able to access even the root directory of my mac .. I am able to create there a file and read and write to/from it running an iOS application in the simulator. By the way, there are no words about ios or iPhone in the question ... The same syntax I use at macOS ... – user3441734 Nov 08 '16 at 19:27
