Can someone help me with this Swift After Lesson Challenge?

So I’m having trouble with Chris’s, Learn Swift 2019 After Lesson Challenge Number 4.

I really have a hard time in understanding what it meant by, "Create the logic by saving the resulting answer and saving it in the result variable. print the result before breaking out of the switch statement.
" Can anyone help me, that would be very appreciated

Oh wait nvm, I checked out that there was an Answers File for these challenges, It was just a bit hard to understand the wordings
