loops.swift 
// Enter your code below

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

Arief, the instructions can sometimes be a bit ambiguous. The challenge wants multiplier to be a constant set to the value 6. And it needs to be declared and initialized outside the loop:

var results: [Int] = []
let multiplier = 6
for i in 1...10 {
    results.append(multiplier * i)
}

P.S., you don't put the values in the array ahead of time. You let the loop do that.

Not sure if I understand your most recent post, but the array must be empty at the beginning.
