Hello Mir rashawn Ali, your problem is in the body of your loop. Your body is a type String. The challenge is expecting a type Int. The challenge states; " 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."

One thing I try to do is read the challenge instructions as pseudo code. We want the multiplier "6" multiplied by our numbers in the loop. So in my code I simply created a variable "value". I then use the append function to add my variable to our results array.

Hope this helps you.

var results: [Int] = []

let multiplier = 6

for numbers in 1...10 { 
var value = numbers*multiplier
results.append(value)
}
