title: How I fix a "GADInsterstitial.h" file not found... but it is in my list?
body: <p>I am having trouble installing a Interstitial ad into my Xcode project. I have download Google Ad Mob 7.0.0 and have continued with the instructions to implement an interstitial ad. <a href="https://developers.google.com/mobile-ads-sdk/docs/admob/ios/interstitial" rel="nofollow noreferrer">link</a></p>
  
  <p>When I go to <code>#import "GADInterstitial.h"</code> I am getting an error that the file not found. However, as seen in the picture attached the file is there as I added the files to the project. How do I correct this?</p>
