Filter: Learning Higher-Order Functions with Swift

Filter does just that, it filters. Discover how it takes an array containing items of a given type. It loops through them and based on the closure returning true, it keeps the item. The rest it removes. The result is a collection of the same type with the same number or less items. It will be less all the items filtered out.
