Help with my code

Question

Not sure what I am doing wrong here...

filter.swift

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

// Enter your code below

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

You are not returning an appropriate return type of Bool. You need to check if the number is Odd. If it is, then you return true. Else return false.

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

// Enter your code below

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

Paul's right. But here's an opportunity to practice what some call Boolean Zen:

func isOdd(n: Int) -> Bool {
  return n % 2 != 0 
}

Since n % 2 != 0 is going to be either true or false for any n, just return it, rather than returning true or false in an if... else...
