Stuck on Challenge Two For in Loops

Would appreciate the correct/optimum code, every way I have tried hasn't worked.

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

for numbers in 1...10 {

multiplier = numbers * 6

results = [multiplier]
}

Very close. You need to put a let infront of multiplier when you are declaring it as a new constant inside your for loop. You also need to use the .append method to add the multiplier to the array.

Your code would look like this then.

var results: [Int] = []

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