title: Terminal stalling on every command due to Xcodebuild
body: <p>I just updated Xcode to 11.4 and suddenly my terminal (iTerm 3.3.9) is now very slow. Typing a command works fine, but upon pressing enter I often wait 3-4 seconds to perform a simple task (<code>cd</code>, <code>git add</code>, etc). </p>
  
  <p>When I look at the status bar I notice that <code>xcodebuild</code> is running during the time while I am waiting. I'm assuming that the new Xcode update did something that makes this process longer or needs a setting updated somewhere. </p>
  
  <p>I have already tried <code>sudo xcodebuild -license accept</code> and that did not fix the problem. Additionally, there is no <code>xcodebuild</code> call inside of my <code>.zshrc</code> file. </p>
  
  <p>Where can I find out what the terminal is trying to do with Xcodebuild? I suspect identifying the command being run is the first step towards determining how to fix it. </p>
  
  <p>FWIW, this problem also happens in the Apple-provided terminal, so I don't think it's iTerm specific. </p>
