I couldn't figure it out on a Mac. Then I Googled it, and decided I'm better off...

Last night I gave the complete solution in Swift below. Here are the two lines to read the file:

   let path = Bundle.main.url(forResource: "input01", withExtension: "txt")
   var text = try String(contentsOf: path!, encoding: .utf8)

There's no chance in hell anyone learning Swift can figure these two lines out.

Besides, there are immediate additional questions:

- what's a bundle, and why does a Bundle deal with urls?

- What's the difference between Bundle.main.url and FileManager.main.urls, and why one and not the other?

- where does the resource come from?

- how do I read a file from a path?

- Why is String responsible for reading (and writing!) contents of a file? In which world is this good design?
