Fixing the "Cannot invoke count with an argument list of type String" in Swift 2

[kjmcneish]

In Swift 2.0, you no longer use the count() free function to count the characters in a string. You call the count() method on the String's character property instead.

For example, the following code uses the count() function to count the characters in a label's text property:

Code: [Select]

let i = count(self.lblWinnerText.text!)
This should be changed to:

Code: [Select]

let i = self.lblWinnerText.text!.characters.count
All the best!
