everything works in playground

when I have checked this in playground, everything works. Numbers in the array is 7,21,35,49,63,77,91. So where is the problem?

operators.swift
var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if (n % 2 != 0) && (n % 7 == 0)
    {
        results = results + [n]
    }


    // End code
}

Hey there,

Challenges are very picky when it comes to what it wants. Here the instructions say to append the results to the array, so you will need to use the append() method to add the values to the array.

Give it another go with that in mind. :) :dizzy:
