title: Xcode enforcing App extension API only, but I'm not writing an extension or using extension features
body: <p>I've been working on an app since iOS 7, and updated it from 7->8 without a problem, now I'm going to 9 and Xcode is telling me I'm using methods not allowed in an app extension but I'm not writing something constricted to an app extension api.</p>
  
  <p><code>'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.</code></p>
  
  <p>I've had the app running on simulator and device for iOS 9.  This just randomly happened the other day.</p>
  
  <p>Ideas?</p>
