title: ipa file is generated in the release mode but not in ad-hoc mode
body: <p>I am trying to generate my ipa via Mac agent in Visual Studio. When I choose the release mode, it is ok and the Visual Studio shows me this message:</p>
  
  <blockquote>
    <p>The ipa file should be visibile on the build server.</p>
  </blockquote>
  
  <p>But when I try it in ad-hoc mode, it just tells me this error:</p>
  
  <blockquote>
    <p>ipa file was not generated. please check the project configuration </p>
  </blockquote>
  
  <p>I tried the different solutions, for example, I change some configurations in info.plist. But the error is still there. Do you have any suggestion?</p>
