title: Ionic Cordova phonegap-plugin-push did work on IOS but stopped recently with 'kill() returned unexpected error 1'
body: <p>I have added phonegap-plugin-push plugin to an ionic 4.10.2 about two months ago,
  it worked and I left the project alone for a while,
  now when I recompile it (I don't have the working version anymore) it doesn't work.</p>
  
  <p>The only notable difference since then is the console messages:</p>
  
  <pre><code>kill() returned unexpected error 1
  </code></pre>
  
  <p>as I have read they have to do with WKWebview and it <a href="https://stackoverflow.com/questions/58321114/why-i-get-the-console-warning-process-kill-returned-unexpected-error-1-when">was never been fixed</a>, </p>
  
  <p>but no one have ever mentioned it has anything to do with push notifications</p>
  
  <p>I also get <code>PushPlugin skip badge</code> </p>
  
  <p>I don't see any version changes in <strong>package.json</strong> that could indicate a change in versions of plugins.</p>

  <p>nothing have change with Firebase and Provisioning files either.</p>
  
  <p>any ideas? did it happen to anyone else recently? or is it just a coincidence and I should put more effort in searching the problem elsewhere</p>
