title: Xcode 8 won't run my application
body: <p>I'm trying to run a sample app; its source can be found here: <a href="https://github.com/bandwidthcom/catapult-reference-app-voice-ios" rel="nofollow noreferrer">https://github.com/bandwidthcom/catapult-reference-app-voice-ios</a></p>
  
  <p>In commit <code>c669271</code>, before the app was migrated to Xcode 8 and Swift 3, I was able to run it in devices from Xcode 7 - the Simulator wasn't working since one of its dependencies wasn't built for x86_64.</p>
  
  <p>But since it was updated, when I try to run the application on a Simulator from Xcode 8, I get the following error:</p>
  
  <blockquote>
    <p>The operation couldn’t be completed. (Mach error -308 - (ipc/mig) server died)</p>
  </blockquote>
  
  <p>There's a similar error when running on a device, but since I don't have one with me right now, I'll edit this question with further details tomorrow.</p>
  
  <p>I saw it working thrice. The only thing that comes to mind is that I had a clean install of Xcode each time it worked. After something like a reboot, or just a restart of Xcode, I wasn't able to run it anymore.</p>
  
  <p>I don't have a firewall enabled, so the accepted answer to this question (<a href="https://stackoverflow.com/q/24028635/4909026">Swift Playground and Simulator Error (ipc/mig) server died, Unable to boot the iOS Simulator</a>) doesn't solve my problem.</p>
  
  <p>Any ideas?</p>
  
  <p><em>OBS: You have to edit the Config.swift file to be able to build the project: any value in the place of <code>"&lt;replace me&gt;"</code> will suffice.</em></p>
