title: Xcode crashing immediately after archiving
body: <p>This might be a duplicate of <a href="https://stackoverflow.com/questions/58937601/xcode-crashing-after-archive">Xcode crashing after archive?</a>, but I did not see a satisfactory answer in that one.  I'm running xcode 11.3.1.  My app builds and runs in the simulator just fine.  However, when I do Product->Archive, the archive will supposedly complete successfully and then xcode immediately crashes with SIGABRT:</p>
  
  <blockquote>
    <p>UNCAUGHT EXCEPTION (NSInvalidArgumentException): *** -[NSURL
    URLByAppendingPathComponent:]: component, components, or pathExtension
    cannot be nil.</p>
