After working with a customer experiencing issues with iOS unit tests, we noticed the template for iOS unit test projects in Visual Studio is not behaving as expected.
If a Unit Test project for iOS is created in Xamarin Studio and then brought into Visual Studio, everything works correctly and as expected. However, creating a new “Visual C# -> iOS -> Unit Test App (iOS)” project in Visual Studio results in the inability to add PCL projects to said project.
Additionally, if a test  is added to the current Visual Studio template, the test runner app crashes on startup with the following exception:
System.NullReferenceException: Object reference not set to an instance of an object
