title: Xamarin iOS: Deploying app to device or simulator with iOS 15
body: <p>I would like to verify whether my Xamarin iOS app is ready for iOS 15 before it's official release. I've installed the public beta of iOS 15 on my iPad and there seems to be an issue, so I would like to debug it. Unfortunately I'm neither able to deploy the app to my device nor can I deploy it do an iOS 15 simulator, because they are not appearing in the dropdown.</p>
  <p>I did the following things:</p>
  <ul>
  <li>updated MacOS to the newest version (11.5.1)</li>
  <li>updated Visual Studio for Mac to the newest version (8.10.6)</li>
  <li>updated Xcode to the newest version (12.5.1)</li>
  </ul>
  <p>Since this didn't work I've installed the Xcode-beta (version 13.0 beta 4) and changed the SDK location in Visual Studio to Xcode-beta.app.</p>
  <p>Unfortunately there are still no simulators appearing in the dropdown and when I try to deploy the app to my device I'm getting the following error:</p>
  <pre><code>error HE0003: Could not load the framework 'IBFoundation' (path: /Applications/Xcode-beta.app/Contents/Frameworks/IBFoundation.framework/IBFoundation): not found.
  </code></pre>
  <p>Am I missing something? Is it even possible to be able to debug Xamarin.iOS apps with iOS 15 or is Visual Studio just not ready yet?</p>
  <p><strong>UPDATE:</strong></p>
  <p>I've changed my SDK location in Visual Studio back to the stable Xcode version, unloaded and reloaded the project and now I'm able to deploy to my iPad. So I'm not sure whether the stuff I did before actually changed something or Visual Studio just had another unrelated problem previously..</p>
  <p>Would still be good to know how you could get the simulators to work as well.</p>
