title: What memory limit for Apple Notifications service extension
body: <p>I've implemented notifications extension and now try to debug my code, but without any success.
  I tried several approaches how to handle it, for example <a href="https://stackoverflow.com/questions/38140158/debug-notification-extensions/">stackoverflow question</a></p>
  
  <p>When I "attach to process ...", I just see "waiting to attach" message on desired process. If I send push notification to invoke my extension, it just crashes</p>
  
  <pre><code>Message from debugger: Terminated due to signal 9
  </code></pre>
  
  <p>Is it possible that OS just close my extension, because it uses to much memory or it has too big size (~.appex = 20mb), but I can't find guidelines about extension size/number of files, etc.</p>
  
  <p>Any suggestions, help?</p>
  
  <p>Thx in advance</p>
