is it better practice to use switch statements or arrays?

I am attempting to my own quiz app in swift 3 and was wondering, is it better practice to use switch statements or arrays for the questions/answers? Sometimes its hard to tell what is the best practice since many times there are more than 1 way to code things...

Well... In swift arrays (which are data structures) and switching (which is control flow) are very different, but if you are in any program deciding which way you should use to write a program, decide with these in mind:

Keep in mind that these are in order. Ones on the top are more important to satisfy!

  • DRY (Don't Repeat Yourself, the most important!!)
  • Readable (also very important!!)
  • Fast and high performance while running
  • Simple, easy to understand
  • Short
