Swift: Unexpected zoom in ad

Question

I added the MoPub banner ad with the following code:

 self.adView.delegate = self
    self.adView.frame = CGRectMake(0, self.view.bounds.size.height - MOPUB_BANNER_SIZE.height,
        screenWidth, MOPUB_BANNER_SIZE.height)
    self.view.addSubview(self.adView)
    self.adView.loadAd()

For some reason when I run the application the screen doesn't appear fully, but it has a weird zoom. What could be happening?

UPDATE:

I moved the frame of the adView to viewDidLayoutSubviews() like this:

override func viewDidLoad(){
 self.adView.delegate = self
    self.view.addSubview(self.adView)
    self.adView.loadAd()
}


  override func viewDidLayoutSubviews() {

    var screenSize: CGRect = UIScreen.mainScreen().bounds
    var screenWidth = screenSize.width

    self.adView.frame = CGRectMake(0, self.view.bounds.size.height - MOPUB_BANNER_SIZE.height,
        MOPUB_BANNER_SIZE.width, MOPUB_BANNER_SIZE.height)

}

But the error persists, I'm using Auto Layout and Size Classes.

I fixed this issue by myself. When working with Spritekit and scenes, remember to always configure the scene before presenting it, specially the scene's ScaleMode. After setting the scene's scaleMode to: scaleMode= .Fill the zoom stopped happening.
