title: Xcode error with Cocoapod: "The document could not be saved. The file doesn’t exist"
body: <p>I've added the <code>SPGooglePlacesAutocomplete</code> cocoapod to my project -- and I'm getting a really weird issue. When I try to run my project, Xcode says there's an error in one of the Pod's headers:</p>
  
  <p><code>SPGooglePlacesAutocompleteQuery.h:65:23: Unknown type name 'CGFloat'</code></p>
  
  <p>Attempting to adjust anything in that file - such as importing UIKit - results in an error: "The document SPGooglePlacesAutocompleteQuery.h could not be saved. The file doesn’t exist"</p>
  
  <p>What could be making Xcode thing this file is non-existent?</p>
