Challenge Task 2 of 2

Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

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.

We ( we ) are lost need best answer ... so far no work...

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

Hi Ary, I'll like to give your problem a try!

It seems to me that there are two little problems with your code.

  1. Is the var results
  2. for in loop its self.

The variable needs an empty array that will contain ints.

And when I looked at your loop it returns 11 multiples not 10. Remember that in programming language we start counting from 0 and not from 1. So if you only want the loop to return 10 make sure have your loop only 9 times. Everything should look like this. 

var results = [Int]()

for i in 1...9 {
    let multiplier = 6 * 1
    results.append(multiplier)
}
let multiplier = 6 * 1
results.append(multiplier)
