Need help with quiz question.

var results: [Int] = []

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

Doesn't the above code append to the results array all the numbers in the range 1 to 100 that are odd and a multiple of 7?

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

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

Yes it does but I'm guessing the code challenge wants you to use results.append(n) instead.

edit: yup, just did the challenge, it takes your answer fine if you change your "results += [n]" to "results.append(n)"

you still did it correctly, it's just the code challenge only takes it a certain way.
