From the lesson I can still not understand how to limit the loop to only multiplying 1 - 10

The challenge is telling me I have to make sure only the results for 1 - 10 are shown, from what I can tell I am doing it correctly as the lesson taught.

loops.swift 
// Enter your code below
var results: [Int] = [1,2,3,4,5,6,7,8,9,10]

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

Alex,

The task asks that:

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.

You filled the array with incorrect values (1-10). We can add values to the array with the append method. We want to append multiplier * 6. Like so:

var results: [Int] = []

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

we can verify the contents of our array:

results //returns [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]

I hope this helps!

Thank you Thomas, I didn't realize having my values set in the results variable was incorrect.
