Googling and Stealing Code...
Yesterday, clever students did an effective Google search to find a solution to coding the Craps flowchart in a Swift playground. Search, copy, paste, done! (Do they understand the code?! Remains to be seen).
An initial glance at their code makes CG think it was found here.
CG had never heard of the 'Darwin' import in Swift but he will do his homework and actually teach the material that the students found.
