Hi Ryan Herman,

To used Xamarin Unified API you must upgrade your project with Project Migration tool that is exist in Xamarin Studio. You could refer to http://blog.intersoftpt.com/2014/12/crosslight-introduces-support-for-xamarin-unified-api/ for more information regarding it.

Basically the step are the following:
1. Select iOS project and Migrate it by selecting Project > Migrate to Xamarin.iOS Unified API.
2. Remove existing Intersoft.Crosslight.iOS assemblies under iOS project.
3. Add the new Intersoft.Crosslight.iOS Unified assemblies from the bin\iOS.Unified folder.

Please inform me whether your project have been migrate using above step or using other scenario.
If the problem still persist after the migration, please kindly provide me with a sample if possible.

Thanks you.

Best Regards,
Leo

I'm having issue navigating after making a new view controller and trying to navigate to it. I can provide a sample if needed but here is the stack trace.

Maybe you already know of the issue.
