It keeps asking me to append my for in loop (multiplier) into the results array variable. I don't now how to do that

Please help

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

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

First off your results array should start off as empty as ... well... you don't have any results yet. Then we're going to loop through the numbers one to ten and multiply each by 6. The results array at the end should look like the following [6,12,18,24,30,36,42,48,54,60]. However, you won't be able to tell just by the challenge because you'll never actually print the results. See my code for clarification.

// Enter your code below
var results: [Int] = []

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