please help dont understand the question

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.

loops.swift 
// Enter your code below
for multiplier in 1...10 {
  print("\(multiplier) time 6 is equal to \(multiplier * 6)")
var results: [Int] = [multiplier * 6]
}

You moved the array within the for loop, this is wrong because in each iteration the array will be emptied and when the loop is over there won't even be a results array. So you'd go through all the multiples but they wouldn't be stored anywhere.

You should define the result : [Int] before you iterate through 1 through 10.

var results: [Int] = []

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