Part 6: Joining the dots with View Controllers — the UI testing part (with bonus Enums)

Hi, great tutorial. I move from objective c and trying to get use to the synatx of swift and the new testing framework that Apple is trying to push developer into.

However i have a question regarding the switch statement for button. Usually in this case, i prefer to spilt into different button IBAction rather than having a switch or if else. So my question is there any reason why do you prefer it this way?
