title: Get info about iOS Simulator traffic
body: <p>When using a mobile Android Wi-Fi hot spot on macOS Catalina and <a href="https://member.ipmu.jp/yuji.tachikawa/MenuMetersElCapitan/" rel="nofollow noreferrer">MenuMeters</a> utility to see total mobile traffic I noticed that every time I launch iOS Simulator (tested on iPhone Pro Max  and iPhone SE 2nd generation both with iOS 13.5) it starts downloading huge amounts of data (approx. 450-800 MB) <em>on every launch</em>, so it gets rather expensive. I know that's Simulator because when I quit it traffic stops.</p>
  <p>So I'd like to find out what and why Simulator may download maybe to try to block/work around this expensive operations.</p>
  <p>I tried to use Charles and Proxyman to detect addresses Simulator could connect to - but with no avail, I cannot see this hundreds of megabytes there. Another option was Wireshark, but I do not know how I could use it to get what I want (as I imagine it should be some addresses from where Simulator could download data).</p>
  <p>Could you please give me some advices how to get needed info with these applications or in some other way.</p>
  <p><strong>Edit</strong></p>
  <p>Thanks to accepted answer and Little Snitch I was able to catch and block &quot;evil&quot; connection</p>
