Hi Haitham,

  • We don't need to edit the array declaration. We'll fill it with values once our for loop runs and new values are appended to it.

  • Since multiplier is an int and not a string, we don't want to put it in quotes when we make our call to the append method. Also, since we are using it as an argument to a method, we'll put it in parentheses.

var results: [Int] = []

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

Hope this helps!
