title: Illegal Configuration: Compiling IB documents for earlier than iOS 7 is no longer supported
body: <p>I recently updated to <strong>XCode 9</strong>. When I build the app it says <strong>"illegal configuration"</strong> for some storyboards in my pod files. I tried to recreate the storyboard files but it doesn't help.</p>
