Did i actually did this one right ?

Here's the code

// Enter your code below
var results: [Int] = [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]
for multiplier in 1...10 {
    print("\(multiplier) \(6 * multiplier)")

Hi Miguel,

The answer is no. You hard coded the array in line 1 with the correct answer.
Surprising that they accepted this in the code challenge.

The correct answer should look more like the code below. The code challenge asks you to use a loop to generate the array by appending the new values to the array.

// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
    results.append(multiplier * 6) // append values * 6 to results array

I hope that helps,
