iOS Closures in Swift 2 Building Standard Library Functions Using Filter

Code Challenge

Is this not the right way to write this code?

filter.swift
let numbers = [10,423,802,765,943,12,405,230,1348,128,237]

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

let oddNumbers = numbers.filter(isOdd)

The exercise wants you to use a closure to create the odd number list.

Here's how you do it (just take your isOdd function calculation and pass it via the closure):

let numbers = [10,423,802,765,943,12,405,230,1348,128,237]
let oddValues = numbers.filter { $0 % 2 != 0 }

Okay i get it now! Thank You!
