I don't understand what I'm doing wrong...

"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."

My response is below.

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


for multiplier in 1...10 {multiplier * 6}


results.append(multiplier)

Inside the body of the loop you need to get a value and append it to the results array so it should be like this:

for multiplier in 1...10 {
    // let value...
    // array.append(something)
}

So I just didn't put it inside of the body? That's the issue?

Yep! And also you don't append the result, but the iterator.
