How to get length of text enter in search bar?

Question

I want to get the length of the text that is entered in a UISearchBar

I use the function that is called when the the searcbbar text starts editing.

func searchBarTextDidBeginEditing(searchBar: UISearchBar!) {
    println("EDITING")
    //TODO: Get length of text entered in searchBar
}

This doesn't work:

func searchBarTextDidBeginEditing(searchBar: UISearchBar!) {
    println("EDITING")
    //TODO: Get length of text entered in searchBar
    //Doesn't work. Error: String doesn't have a member named length
    searchBar.text.length
}

How can i retrieve the length of the entered text?

Ended up doing this:

searchBar.text.bridgeToObjectiveC().length

The problem is simply that the text property, like most objects arriving from the Cocoa API, might be nil. You have to assure Swift that it is not. Like this:

let len = countElements(searchBar.text!)
