title: Remove Content and Frame layout guides from UIScrollview
body: <p>I made a pod Xcode 11 and iOS 13, created an UIScrollview and set my content there.</p>
  
  <p>While installing on an older main project, this alert message shows:</p>
  
  <blockquote>
    <p>Content and frame layout guides before iOS 11.0</p>
  </blockquote>
  
  <p>I can see the said layout guides in Interface Builder:</p>
