I was able to debug my Xamarin.iOS app on my physical device and simulators just fine until this morning. I think it has something to do with the recent iOS update. When I try to deploy to my physical device (iPad) I get this message now:

error HE0003: Could not load the framework 'IBFoundation' (path: /Applications/Xcode.app/Contents/Frameworks/IBFoundation.framework/IBFoundation): not found.

And I can't deploy on any simulator anymore, I get this message

Lower the deployment target to see older simulators or check you Apple SDK path

I didn't have these problems yesterday and I've been working on my app for months without this problem. I updated Visual Studio, Xcode, and my Mac, but these problems still persist. Any idea how to fix?
