Hi nader adam,

Did you come from a java course? ;) You can't insert new data into an array with results[multiplier] = 6 * multiplier.

Use one of these instead, I prefer the first one because its simpler:

// Enter your code below
var results: [Int] = []

for multiplier in 1...10{
  results += [6 * multiplier ]
}

or:

// Enter your code below
var results: [Int] = []

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

Good luck!

You need to use the Array type's append method.

var results: [Int] = []
for multiplier in 1...10 {
    results.append(multiplier * 6)

}
