iOS Swift 2.0 Collections and Control Flow Control Flow With Conditional Statements Working with Logical Operators

I understand the if loops but still stuck.

How do I tell it that I only want even or odd numbers without writing in 50 numbers manually?

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

for n in 1...100 {
    // Enter your code below

    // End code 
}

use use the logical operators you would've learned about earlier, and some basic maths operators too

var results: [Int] = []

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

so this says, that for every number between 1 to 100,

if that number is divisible by 7, AND divisible by 2, add it to the results array!

hope this helps
