title: xamarin ios Why cant i select a Simulator
body: <p>I am very new to Xamarin, and i have been following the <a href="http://developer.xamarin.com/guides/ios/getting_started/hello,_iOS/hello,iOS_quickstart/" rel="nofollow">Hello.ios QuickStart Tutorial</a> and the app builds, But i cannot select a simulator for debugging.</p>
  
  <p>My only options in debug are Default or IOS Device. 
  I have made my app the starting application and i have the xcode simulator running. I also went into xcode and updated the simulation to 7.1 i think, but i still cannot select a simulation type.</p>
  
  <p>I even tried to go into project-->Active Configuration and tried to select Debug|iphoneSimulator, but it defaults back to just Debug|iPhone</p>
  
  <p>can anyone help me
  Thanks</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>i am also getting this error : no valid ios code signing keys found in keychain
  I dont know if that is caused by my issue in my question.</p>
