title: Xcode 8 App installation failed, unknown error occured
body: <p><img src="https://i.stack.imgur.com/rd34E.png" alt="Error message[1]"></p>
  
  <p>The following error occurred when I tried to run a project on my iOS device. Running it on a simulator works fine.</p>
  
  <p>The other weird thing is that I am able to run my other projects on my device, only this particular project that is giving me this error.</p>
  
  <p>I tried all the solutions I'm able to find:</p>
  
  <ol>
  <li>Cleaning the project, deleting derived data</li>
  <li>Restarting Xcode, my Mac, and my iOS device</li>
  <li>Deselect 'Automatically manage signing' in the testing Target.</li>
  <li>I couldn't delete the app from my device and re-install it because it wasn't installed on my device before.</li>
  </ol>
  
  <p>Any help would mean alot to me! I am using Xcode 8.1 with Swift 3.0, running on a iOS 10.1.1 device.</p>
