Appending Data from "For..in loop"

I have to get the values from my for in loop and append it to the results variable. Can't figure out how to do so.

loops.swift 
var results: [Int] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

for multiplier in 1...10 {
    print(multiplier * 6)
}

You need to leave the array empty, create a multiplier constant outside the loop, and rather than print the results of the multiplication, append them to the array.

var results: [Int] = []
let multiplier = 6
for i in 1...10 {
    results.append(i * multiplier)
}
