Hi, There are 2 problems in your code:

  1. You are assigning "number" to multiplier, which is not possible because the number variable is working only inside loop scope. Also, assigning an iterating value to a constant is not possible.
  2. You should add the resulted value to the array instead of printing it.

Below is my solution. 

var results: [Int] = []

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