What was the purpose of #?

Can you refresh my mind, please? I forget why is important the #.

For example, in this excersive Amit use like this:

Write a function that determines if a number is divisible by another. It will do the following:

func isDivisible(#number1 : Int,#number2 : Int) -> Bool? { if number1 % number2 == 0 { return true } else { return nil } }

The '#' is for named parameters:

So instead of doing something like isDivisible(14, 12) you can do isDivisible(number1: 2, number2: 12)
