For in loops swift task 2 of 2

This is the error

Your array needs to contain the first 10 multiples. Make sure your range goes from 1 to 10

loops.swift 
// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
 print("\(multiplier) times 6 is equal to \(multiplier * 6)")
}

But its correct please tell me what i did wrong

I am finding this has not been very well explained. I can understand it as well.

Oh for step 2 it asks you to append to the results array. Your print statement is valid but the question is asking something more in the second step. Here's a walkthrough of the whole problem I did yesterday:

  • Create a for in loop that iterates over a range from 1 to 10. Name the temporary constant "multiplier".
for multiplier in 1...10 {
}
  • Use multiplication to get the multiples of 6 from the loop
for multiplier in 1...10 {
multiplier * 6
}
  • Append it to the given array "results"
for multiplier in 1...10 {
results.append(multiplier * 6)
}

Your code will work for step 1. I just tested it in the challenge and it went through!

Your array needs to contain the first 10 multiples. Make sure your range goes from 1 to 10
