title: Xcode 10.2, Swift 5, Command compileSwift failed while build the program with Release Scheme
body: <p>I'm using Xcode 10.2, Swift 5.</p>
  
  <p>With Debug scheme, no issue happens, but with Release scheme when I build or archive, it shows Command compileSwift failed with a nonzero exit code. </p>
  
  <p>I've tried delete DerivedData / Clean / pod deintegrate &amp; pod install &amp; pod update. None of these works.</p>
