title: How to troubleshoot/resolve "Signal strength query returned error" logs that are appearing in Xcode 10.1/iOS 12.1?
body: <p>Recently updated to iOS 12.1 (from 12.0), Xcode 10.1 (from 10.0) and seeing a flood of error messages in the Xcode console when debugging on my physical device like the following:</p>
  
  <p><code>[NetworkInfo] Signal strength query returned error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied", descriptor: &lt;CTServiceDescriptor 0x28051d700, domain=1, instance=1&gt;</code></p>
  
  <p>I get a couple of these logs every couple seconds, the only thing that changes is the hex value for the CTServiceDescriptor. There have been no code changes so I have to assume its related to the iOS or Xcode updates. </p>
  
  <p>As far as I can tell it doesn't appear to have any performance impact, the app is operating as expected and my phone is working (its even updating its signal strength!). I've been unable to find anything helpful/relevant across Stack Overflow, Google, or the Apple Developer forums though I made a similar post to the latter that I'll link here once the post is approved. </p>
  
  <p>Any suggestions/insight into how I could troubleshoot this further or resolve would be greatly appreciated. Thanks!</p>
