title: How to fix Xcode Playground Communication Error on Xcode 13.2.1 on IOS Big Sur 11.6, please?
body: <p>I am trying to test some code on Xcode playground. I am receiving the following error:</p>
  <p>'Failed to prepare for communication with playground for an unknown reason.'</p>
  <p>When I press the play button nothing happens - I have copied the code exactly from a course I am doing which shows results on the demonstration.</p>
  <p>I am using Xcode 13.2.1 and on a MacBook Pro (Late 2013 model) running Big Sur 11.6 - I cannot update any further.</p>
  <p>I have not had any trouble using the main part of Xcode for my own and cloned projects with no such similar errors.</p>
  <p>I have tried to restart Xcode, I have deleted the playground and created a new one and tried using different code. I have searched on the help section on Xcode and on Apple Development as well as on here with no solutions found.</p>
  <p>This is the code which I am testing with, which on the demonstration returns 'hello'.</p>
  <blockquote>
  <p>func greeting () {
  print (&quot;hello&quot;) }</p>
  <p>greeting()</p>
  </blockquote>
  <p>Thank you :)</p>
