iOS Swift Collections and Control Flow Control Flow With Conditional Statements Working With Logical Operators

It's fine for != values but as soon as I put it as n % 7 = 0 the code breaks. It doesn't appear to make sense to me.

I did n % 7 != 0 && n % 2 != 0 and it works fine. as soon as I change it to n % 7 = 0 though it doesn't work.

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

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

}



    // End code 
}

Hi Courtney,

Almost everything in your code is correct except for the check if the n is a multiple of 7 is setting it to 0 instead of checking for equality. Try something like the code below and that should work.

var results: [Int] = []

for n in 1...100 {
    if(n % 2 != 0 && n % 7 == 0) {
        results.append(n)
    }
}

Hope this helps ?

Thanks Paul! So simple!!!
