1. Create a new xcode project
  - You can skip this if you're adding the playground to an existing project
2. File > Save as workspace - save workspace in project folder
  - You can skip this if you're adding the playground to an existing workspace
3. File > Playground - create new playground in project folder
4. Drag playground in at the _workspace_ level (root item, i.e. _not_ under the project)
5. Add a new Framework to your project (I usually name mine something like 'PlaygroundKit')
  - You don't need to include tests
  - Choose 'None' for Enbed in Application
6. Make all project files you want to be accessible to the playground are members of the new target
