489 PointsHaving trouble appending to array
I'm still not sure how to append to the array. Any ideas?
// Enter your code below
var results: [Int] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for multiplier in 1...10 {
}

Your loop looks good, so now you could use the "append" method on the array to add a new element, giving it a value six times larger than the "multiplier".
So that would look like this:
var results: [Int] = []
for multiplier in 1...10 {
results.append(multiplier * 6)
}
