10,885 PointsAm I doing something wrong?
I'm getting a message when I submit my code saying "Make sure you're appending the correct values to the results array in order to pass the challenge".
I've tested my code in a Swift Playground and it doesn't say I have any errors and the results array has all of the values inside, not sure what I am doing wrong?
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if n % 2 != 0 && n % 7 == 0 {
results += [n]
}
// End code
}

The loop will return a single Integer every time it iterates through itself, so nstead of using the unary operator += to add what would need to be another array to the results array, try using the .append method. :)
Keep Coding!

Treehouse TeacherIndeed it is the solution checker ensuring that you use append here. I'll update this to include concatenation

4,233 PointsHi, I'm having the same issue today. Could the simulator still be updated to include concatenation, or could the question be updated to steer the user away from concatenation?

Treehouse TeacherHey John,
Could you post what error you're specifically getting when you use concatenation. It should work but I might be missing a particular variation

10,885 PointsHey Jason, thank you for your answer, the append method worked.
Are you able to explain why the append method worked, but concatenation wasn't accepted? I'd just like to know so I don't make the mistake again. It's pretty confusing since it worked for me in Xcode.
Thanks!

Treehouse Moderator 145,860 PointsHey Denny,
It does work in Xcode's playground, and as far as I can tell, it's valid syntax and produces the same result.
In this instance, however,I think it's probably just the code checker for the challenge being picky and particular to a certain way (here the
.appendmethod).But I would like Pasan Premaratne to just confirm please. :)
