title: Showing all deprecated warnings in Xcode
body: <p>How do I show all deprecated warnings in Xcode for my iOS app?</p>
  
  <p>Clicking on the <code>Issue Navigator &gt; Buildtime &gt;</code> then scrolling down to <code>Deprecations</code> only seems to show deprecations for opened or previously-opened files. When I open more files, more deprecations appear. I'd like to see a complete view of all deprecated methods across all files.</p>
