title: Xamarin Forms - XAML Hot Reload encountered a problem and failed to start
body: <p>I have created a brand new Xamarin forms application. When I want to start the iOS app, it shows a blue screen (I think the default launching screen) and gives the output beneath.</p>
  
  <p>Also, when I click on the app again in the emulator after I had started it, it works, but for my other project it doesn't, it puts the app back to the background.</p>
