I need help on the append function . Im trying to append my loops results into an empty array .

var results: [Int] = []

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

You have two issues:

1 - The append method is on the array(results) and not on an integer(multiplier)

2 - When you append the value to an array, you just append the value without adding the brackets([])

var results: [Int] = []

// Also, I would change numbers variable to number, 
// which in reality, you are appending a single number at a time and not an array of numbers.
// It reads better by saying for each number in 1 through 10 instead of for each numbers in 1 though 10
for numbers in 1...10 {
  let multiplier = numbers * 6 
  results.append(multiplier)
}
