I'm confused by what the question is asking... what am I missing here?

Any ideas?

loops.swift 
// Enter your code below
var results: [Int] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

let multiplier: for multiplier in {1...10}

Righto, first up we are not pre-populating that empty array like you have done. We are going to append to that within our for loop.

Next up we are going to set a constant called multiplier that will be the Int 6 so that we can use that inside our for loop.

Finally we are going to operate a for loop by creating a range from 1 to 10 inclusive and we are going to take that number each pass through the loop and multiply it by that multiplier Int and append the result to our results array.

The code would look something like this.

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

let multiplier = 6

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