They want you to use the for-in loop. You can use any variable name you want. Here I used i. Then they want you to test each i to see if it is a 1, 2 or 3. I did this in an if... else if... but you could probably have used a switch statement instead, although I didn't test that. The surprising thing is that the challenge required the use of println(), rather than print(), as println() which is no longer part of Swift 2.0. But maybe this course is still Swift 1.0.

let months = [1, 2, 3]
for i in months {
  if i == 1 {
    println("January")
  } else if i == 2 {
    println("February")
  } else if i == 3 {
    println("March")
  }
}

This course is for Swift 1.2. If the course is for Swift 2.0, then it will say in the course name, else it is 1.2.
