how to know how many words contains in UITextView

I am making UISearchController with google search. And I face with problem, how many words contain in UISearchBar.text that I will can make different actions. Or how to separate different words are separated space? Also I want to know, how to count words in UITextView.

My try

func searchBarSearchButtonClicked(searchBar: UISearchBar) {
    let text = searchController.searchBar.text!
    if text.containsString("www.") {
        let url = NSURL(string: "http://\(text)")!
        let request = NSURLRequest(URL: url)
        webView.loadRequest(request)
    } else {
        if text.containsString(" ") == false {
        let url = NSURL(string: "https://www.google.com/#newwindow=1&q=\(text)")!
        let request = NSURLRequest(URL: url)
        webView.loadRequest(request)
        } else {
            let url = NSURL(string: "https://www.google.com/#newwindow=1&q=\(text)")! // it is wrong
            let request = NSURLRequest(URL: url)
            webView.loadRequest(request)
            print("two words")
        }
    }
}

Sorry, I misread your question...

//Separate all words into an array
let allText = SearchText.text.componentsSeparatedByString(" ")

//then count the array
var wordsCount:Int = allText.count

To count chars of a UITextView.text you could use count(UISearchBar.text)
