Swift - CGAffineTransformInvert: singular matrix. UITextView & iAd

Question

I have View Controller with UITextView and in the bottom I have iAds.

When I access the View Controller I get an error: <Error>: CGAffineTransformInvert: singular matrix. Why?

Everything works fine, but when I change from Portrait to Landscape or vice-versa I get this error twice.

Maybe something is wrong with the UITextView and the iAds?

Answer 1

That's absolutely ok. Dont worry about this. That's Xcode trouble. iAd would working fine in production.
