title: how to use Replaykit to record screen in background of outside the app
body: <p>I followed some tutorials to implement a screen recorder with <code>Replaykit</code>. for example this one <a href="https://www.appcoda.com/replaykit/" rel="nofollow noreferrer">https://www.appcoda.com/replaykit/</a> . </p>
  
  <p>it works fine and no special problem exists. but the main problem is that it does not record in background. I mean when I leave the app while still recording and touch Home button then recording will be stopped untill I open the app again. I wonder to know is it possible to record background with the help of <code>Replaykit</code>? if so please give me some brief explanaition how to do it. Thank you. I appreciate any kinds of help</p>
