Looping over Ranges code challenge: I can't seem to get the results array to contain the new looped array

var results: [Int] = []

for multiplier in 1...10{
    print("\(multiplier) times six is equls to \(multiplier * 6)" )
    results = [multiplier]
}

In Xcode the loop area seems to be working fine but when I call results outside of the loop I seem to get the following answer [0]10 . I have a feeling it's a silly scope issue i'm having here

Hi Diego,

Your loop looks fine - the issue is with creating the array.

What you want to do is multiply multiplier by 6 and append that value into the results array. At the end of the loop, results will hold [6, 12, 18, 24 ... etc ]. There's no string to output.

Try with something like this:

var results: [Int] = []

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

I hope that helps,

Steve.
