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?

This happens only when you import iAds – Lumpkin

Any progress with this? – Graduate

No, even the last XCode GM seed don't clear the error... – Lumpkin

Put a breakpoint in CGPostError. When it's hit, type bt in the debug console. Copy the stack trace and paste it into your question. – Landpoor

@robmayoff having similar issue, stacktraces are pastebin.com/eZqh0kGs and pastebin.com/X5VnxM7p Looks like it happens when test ads are not working - otherwise everything is ok. Not related to swift though - I'm using objectve-c with xcode6+ios8 – Tobietobin

Answer 1

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