Not understanding how to append my loop into the array

I have my multiplier, but I can't figure out how to append the array. Should I use results.append( )?

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

  for multiplier in 1...10 {

You're loop is correct. But sometimes the instructions are a bit hard to decipher. What they want is, first, a constant declared outside the loop named multiplier, and second, that times the loop counter added to the array. There are several ways to do this. Here's one that the editor will accept:

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