Hello friends! why is this wrong?

filter.swift 
let numbers = [Int](0...50)

// Enter your code below

func isOdd (number: Int) -> Bool {
    if number % 2 == 0 { return true }
    else { return false }

Hi Pablo,

You are so close! Just reverse the logic.

number % 2 == 0 // this means the number is even

The final code looks like this

let numbers = [Int](0...50)

// Enter your code below

func isOdd(number: Int) -> Bool {
  if number % 2 == 0 {
  return false
  } else {
  return true
  }
}

I hope that helps,

Mike
