Why isn't this code working?

Hello, I and doing a code challenge and I don't exactly know what to do. If someone could please explain to me what is happening that would be great.

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

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

Hi Brendan -

You do not need to print anything, the challenge is asking you to append

var results: [Int] = []

for multiplier in 1...10 {

results.append (multiplier * 6)

}

In the for loop 1...10 you are taking the value and multiplying it by default 6 for each value in 1 through 10 you are using the append method to append the multiplier * 6
