iOS Swift Basics (retired) Control Flow If Statement

Control Flow / For in loop [Help]

"You are provided with a constant array named months that contain 3 consecutive numbers starting at 1. Using a for-in-loop and an if statement, print out "January" when you encounter a 1, "February" when you encounter a 2, and finally "March" when you encounter a 3.

This is one of the challenges that i'm having trouble figuring out. i attached my code and i would really appreciate it if someone could explain my error.

Thank you.

months.swift 
let months = [1, 2, 3]
for month in months {
  if month == [0] { 
     println("January") 
     } else if month == [1] {
      println("February") 
      { else if month == [2] {
        println("March") 
        }

Remove the square brackets in each of your lines testing the number values. Since you're looping over the array, each element is just a number rather than an array contacting just that number.

Hi Jesse,

Along with what krilnon mentioned you're numbers are incorrect as the array values are 1, 2 and 3 whereas you've started with the number 0 and ended with 2, instead you should have the following.

let months = [1, 2, 3]

for month in months {
  if month == 1 {
    println("January")
  } else if month == 2 {
    println("February")
  } else if month == 3 {
    println("March")
  }
}

Happy coding!
