i cannot append this information to an array

i am trying to append the 6 times table (from 1-10). it keeps bringing up an error how to i do this?

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

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

result.append (answer)



}

The code should compile and run, what is your expected result? An array with 10 numbers [6,12,...60]?

Are you certain the array your are appending to is the right name? In my challenge it shows the array defined as results but you append to result.

You don’t need to create a var answer or use a print statement. The last part is VERY close. Don’t overthink the problem.

So should it be:

var results: [Int] = []

for multiplier in 1...10 { results.append("(multiplier) times 6 is equal to (multiplier * 6)")

}

I get an error of:

swift_lint.swift:11:20: error: cannot convert value of type 'String' to expected argument type 'Int' results.append("(multiplier) times 6 is equal to (multiplier * 6)") ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You're appending the string to an integer array. All that needs to be appended to the array is the multiplication of multiplier * 6.

You just misspelled the array name, It's results instead of result. Also you don't need to create a print statement for this task, the task is only to append the values to the arrays. Also It's not wrong, but you don't need to create a variable to store the values, you can simply do like this:

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

Keep in mind that is this challenges you have to type exactly the same name as It's required, otherwise the challenge will not accept your answers, even if your code is write.
