What's wrong with this switch statement in the for-in loop?

let months = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]

for month in months {
    switch month {
    case month == 1: print("January")
    case month == 2: print("February")
    case month == 3: print("March")
    default: print("Not Q1")
    }
}

Hi Laurie,

You don't need to add an == operator for switch statements; that specific comparison is already implied by the fact that you're doing a switch statement. Each case statement is like saying, "compare the value of this case to the value of whatever we're switching on." Fix that and everything should work as you expect :)
