Need guidance with this loops challenge

I need guidance on how to tackle the second part to my code challenge regarding loops, this part of the challenge reads " Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. Once you have the 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] = [1,2,3,4,5,6,7,8,9,10]
for multiplier in 1...10 { 
print ("\(multiplier) times 6 is equal to \(multiplier * 6)") }

You were overthinking it. :)

Your for loop is spot on, but they are not wanting you to pre-populate the array. They are wanting you to append to the array. In that case your code would look like this.

var results: [Int] = []

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

Keep up the great work! :)
