Answer 1

I don't know about Swift 2.3, but I think the syntax for escaping a keyword hasn't changed. After all, it's not a major update.

You can use the ` character to escape a keyword so as to use the keyword as an identifier for a variable, method or something else. So you can do this do create a variable named var:

var `var` = 0

So if you just write:

FileManager.`default`()

it should work.

btw I just looked up NSFileManager in the docs. And I found that there is no default() method. Is the docs outdated or something?

Answer 2

This problem is fixed in Swift 3, and the backticks are no longer necessary. Note that the default manager is now a class property rather than a class method. So the correct syntax is:

 FileManager.default
