Unit testing Swift 2.0, @testable import, and scheme targeting issues

I have recently converted my app, and unit tests over to Swift 2.0. I am using @testable import AppName in my Tests.swift files.

Due to an issue with not being able to execute subclasses in multiple targets (see here for the issue), my class EntityName can only be of Target Membership AppName, and NOT AppNameTests.

The problem is, once I switch over to the AppNameTests schema to run unit tests, code in the module AppName can't find the class EntityName and I get

Use of undeclared type 'EntityName'

How do I get AppName to compile when running tests from the AppNameTests scheme without that entity class not a member of the scheme?
