How do I append the results of the loop to the array?

So I am working in the Playground right now so I can see it run:

I currently have:

var results: [Int] = []

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

results.append(WHAT GOES HERE)

*I thought it would be (multiplier) but that is not an identifier...

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

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

results.append()

Taylor,

You want to append the value of multiplier * 6 to the results array for every iteration of your for-in loop. Right now, you are calling results.append() once, after the for-in loop is done executing. So, you need to move results.append() into your for-in loop, then have your multiplier calculation be the parameter of .append()

It should look like this

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

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

Thats where you put your calculation, multiplyer * 6. But results.append(multiplyer * 6) needs to be inside the body of the loop so it gets used for the amount of times you have choosen.
