Hi Scott,
I could not get this to work in a playground using CocoaPods. I’m having the same issue as reported in Playground does not execute on first chapter
I am using CocoaPods version 1.5.0 and Xcode 9.3. I did not try to use an older version of CocoaPods - it didn’t work for some people in the above thread, and doesn’t feel like the right way to fix it.
I did however get this to work using git submodules. See my reply at Playground does not execute on first chapter - #17 by scarter
