i dont understand how to ammend the first line of code

var results: [Int] = ?

I am stumped on how to add the for in code on the first line and ammend it to the variable results line of code.

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

Hi there,

a short answer to your question: first line should stay first! In the first line, you have a definition of the array that you will need to use later on.

So your line:

for multiplier in 1...10 { multiplier * 6 }

is fine, but should rather go after the array definition and also you don't store your result (multiplier * 6)* anywhere, while you should have something like:

myArray.append(newArrayValue)

So, let's sum it up:

1st part of the challenge, just put 'for-in' definition after the array definition:

// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {

}

Then fix loop with your code, but remember to add result at the end of the array (using append method):

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

That's it!

Cheers! Jarek
