LibGDX - Ads on iOS

Question

I'm making an application using LibGDX and RoboVM, and I'm stucked in a problem with the Google Mobile Ads Framework. I've search everywhere but nothing resolved my error.

If I declare this framework in the robovm.xml like this

  <frameworkPaths>
    <path>libs</path>
  </frameworkPaths>
  <frameworks>
    <framework>UIKit</framework>
    <framework>OpenGLES</framework>
    <framework>QuartzCore</framework>
    <framework>CoreGraphics</framework>
    <framework>OpenAL</framework>
    <framework>AudioToolbox</framework>
    <framework>AVFoundation</framework>
    <framework>GoogleMobileAds</framework>
  </frameworks>

When I'm going to create the IPA it gives me this error.

How can I solve this??
