title: Targeting iOS 11.0 but still getting warnings: is only available on iOS 10.0 or newer
body: <p>I have both project and target deployment target set to 11.0. I've also deleted derived data, cleaned and rebuilt (many times)... and I am still getting these errors.  Is there something else I could be missing? I did change the deployment target from 9.x to 11.0. Maybe I missed something.</p>
