Where does one see XAML parse errors in forms.iOS?

I'm using Xamarin Studio on OS X with the iOS Simulator to work on the iOS version of a Xamarin Forms app. I'm used to normally developing Xamarin.Android with forms and, in the Android framework, when there's a XAML parse error, the cause of the error is output to the console and logcat. In iOS, XAML parse errors don't seem to throw exceptions and there's no console output, instead a View backed by the broken XAML simply isn't loaded. How do you debug XAML errors when developing a Xamarin.Forms app for iOS?
