NSRange to Range

Question

How can I convert NSRange to Range in Swift?

I want to use the following UITextFieldDelegate method:

Answer 1

You need to use Range instead of the classic NSRange. The way I do it (maybe there is a better way) is by taking the string's String.Index a moving it with advance.

I don't know what range you are trying to replace, but let's pretend you want to replace the first 2 characters.

var start = textField.text.startIndex // Start at the string's start index
var end = advance(textField.text.startIndex, 2) // Take start index and advance 2 characters forward
var range: Range = Range(start: start,end: end)

textField.text.stringByReplacingCharactersInRange(range, withString: string)
