title: How to fix "nw_connection_receive_internal_block_invoke" (console)
body: <p>I'm configuring a new Firebase app in Xcode, but get "nw_connection_receive_internal_block_invoke [C1] Receive reply failed with error 'Operation canceled'" printed repeatedly in the console. What should I do to fix this?</p>
  
  <p>This is in Xcode 11 Beta 3, and I've tried creating a new project altogether since the original was created from an older version of Xcode, yet I still get this error printed repeatedly in the console even though all I've done is run it once after configuring.</p>
  
  <p>I expect to see no errors in the console, yet this error is printed many times.</p>
