xcode - Playground Import: No Such Module 'Foo'

Question

I've diligently followed the Apple instructions to import a custom module into a playground, including the instructions here. And yet I get:

Playground execution failed: /var/folders/z3/kd0nj4ln1rgcpm8bdz7067wh0000gs/T/./lldb/1874/playground1.swift:7:8: error: no such module 'Foo' import Foo

How can I recover to a working Playground import? [Edit: Note, two answers have produced detailed instructions to associate a playground with a framework; I have followed those instructions but no luck. The solution will need to involve reconfiguring something in Xcode; my installation is apparently broken]
