Don't understand what the task is asking for.

Do you want me to add the results of the multiplication to the results array? I do not understand what the task want me to do

//Three solutions for that doesn't work.

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

for multiplier in results{
    var multipleResult = multiplier * 6
    results.append(multipleResult)
}

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

var multipleResults = []
for multiplier in results{
    multipleResults.appends(multiplier * 6)
}

The challenge isn't asking you to iterate over an array, it's asking you to iterate over a range. Then it wants you to append each result to an array of integers called results:

var results: [Int] = []

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

Maybe that would have been clearer if that Enter your code below comment would have been below the existing results array.
