How do you append the value to results?

Question

How do i append the value to results? and how come in this challenge there is a Int array(var results: [Int] = []), but when I tried it in xcode, it gave me an error.

loops.swift

// Enter your code below
var results: [Int] = []
let number = 1...10
for multiplier in number {(multiplier * 6)}
results.append()

Your solution is very close to correct, in fact you have all of the code for the solution written. You can solve the challenge by simply rearranging your code a bit.

To append something to an array you can indeed simply use the .append method, just like you do in your solution, however you need to pass in the value that you want to append as an argument to the method. In addition you have to append the results within the loop, currently your appending code is outside the loop.

If you move it inside the loop, and use the value that is already written in the loop as the argument like this:

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

Then you will be able to pass the challenge.
