Xcode 6 error 'URLWithString' is unavailable?

Please help a newbie here. I'm sure this is stupid simple.
I'm following along and learning Xode nicely, but I'm stumped on a basic connection to a URL:

var text = textField.text var url = NSURL.URLWithString(text) var request = NSURLRequest(URL: url) webView.loadRequest(request)

I'm getting the following error for the second line above:
'URLWithString' is unavailable: use object construction 'NSURL(string:)'
(code is part of a brief tutorial at: http://www.lynda.com/articles/build-first-ios-app-swift)
Answer:
Apple changed some of the Swift methods recently, so I've found a few Swift tutorials to be out of date just like what you've encountered. Luckily, it's telling you exactly what to do instead: var url = NSURL(string:text)
