What do I append the results variable with once I have created my loop?

I have completed my loop, how do I append the variable?

loops.swift 
// Enter your code below
var results: [Int] = [6,12,18,24,36,42,48,54,60]

for multiplier in 1...10 {
"\(multiplier) times 6 is equal to \(multiplier * 6)"
}

1) You will want to leave the results array declaration as provided by the challenge

2) Inside your loop use the array's append method:

array.append(item)

This is shown @1:10 in this video. For the challenge array is results and item is multiplier * 6
