title: Did anyone was able to run ios ui test on the simulator after last 18 september 2018 releases?
body: <p>I wrote a few ui test in March/APril using <strong>NUunit 2.6.3</strong> and <strong>Xamarin.UITest 2.2.4</strong>, and I was able to run them on debug mode using the ipad simulator on my mac and also on a physical test ipad. </p>
  
  <p>Today, after last xcode , os and visual studio for mac releases, I get mainly 2 errors:</p>
  
  <p>1) <strong>not able to install the device - agent</strong> ( i tried deleting the xdb folder inside the tmpdir folder) and then I get</p>
  
  <p>2) <strong>unable to contact test backend running app .a common cause is that the app is not properly linked with calabash</strong>, Even if I aded xamarin cloud agent 
  v 0.21.6 (also tried the last one 0.21.7 but with no success)package to my iOS app(I'm using xamarin.forms 3.1), I've added the <strong>ENABLE_CLOUD</strong> key for the build action, and also in the FinishedLaunching method inside AppInitializer I have Xamarin,Calabash.Start() .</p>
  
  <p>Did anyone has any clue? I also tried the last version of <strong>Xamarin.UITest 2.2.6</strong> without any success.</p>
