Summary:
Importing a custom framework into a Playground causes it to cease executing. No errors are reported. The IDE claims the playground executed successfully.

Steps to Reproduce:
1) In Xcode beta (7A120f) create an iOS framework project and add a Swift file with a simple public function.
2) Create a workspace and add the above project.
3) Create a playground and add it to the above workspace.
4) Add a print statement to the playground, notice that it executes.
5) Add an import statement for the framework created in step 1
6) Notice the print statement no longer executes
7) Notice it is also impossible to call the function defined in the framework.

Expected Results:
It should be possible to import the framework and execute functions in the framework.

Actual Results:
Adding the import statement seems to cause the code in the playground to stop executing. 

Regression:
This is a regression from 6.3.1 (6D1002)

Notes:
A workspace demonstrating the issue has been attached to this radar.
