Hi -

I am not sure what is being asked here, nor how to get it:

Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6.

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

for multiplier in 1...10 {
}

Hi Amy,

You got the loop correct, they are asking you to append to the array every loop with the 'multiplier' times 6.

This means the array will be like [6,12,18,24,30 etc]

You would achieve it like this:

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

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

Thank you Damien! It worked, and then I re-read it (yet one more time) and now it makes sense.
