XCode 6 iOS Swift - UIWebView size won't change

Question

I am currently trying some iOS programming. I decided to go with Swift.

Everything is going fine, untill I try to use a UIWebView it won't change it's size to the screen size. I started app development on Android, but afaik there is nothing like relative sizes in iOS right?

Currently this is what my code looks like:

import UIKit

class FirstViewController: UIViewController {

@IBOutlet weak var mainWebView: UIWebView!

var urlPath = "http://www.google.com"


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    loadWebView()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func loadWebView()
{
    var newRect = mainWebView.bounds

    newRect.size.height = self.view.frame.size.height
    newRect.size.width = self.view.frame.size.width

    mainWebView.frame.size = newRect.size

    let requestURL = NSURL(string:urlPath)
    let request = NSURLRequest(URL: requestURL!)
    mainWebView.loadRequest(request)
}

}

I tried different approaches with the above (giving de frame size to the mainWebView, but none work. Maybe it has something to do with the moment I give the commands to change size? Should I change the size earlier in the loading proces?

I also tried this:

mainWebView.sizeThatFits(self.view.frame.size)

But that didn't do anything either.

I would definitely appreciate all help!

Thanks in advance

PS. In the example I am using the values from self.frame.size, but also when using for instance 100 x 100, it just won't change the size...

You need to set the whole frame at once. Setting the size of a UIView's frame directly does not work.

var newRect = mainWebView.frame
newRect.size.width = self.view.frame.size.width
newRect.size.height = self.view.frame.size.height
mainWebView.frame = newRect
