Challenge 2 of 2, Collections and Control Flow

Once you have a 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.

I am not sure what is meant by append it to the results array. I really wish there was a hint section or something.

loops.swift 
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
  multiplier * 6
}

What you want to end up with is an Array containing the results of the multiplications. You can append elements to an array via append(newElement: Element) which is a method you can call on arrays.

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

After the for loop, your results array contains the result of every single multiplication.

There are other ways to do this as well, so I suggest reading through the Apple Swift Docs - Arrays

Hope that helps :)
