How do i use array.filter to filter a class object based on a property?

Question

I\'m trying to filter an array of instances of a class. I\'d like a new array filtered by one of the class properties. Can\'t quite get my head around the way Swift filters

Answer 1

This should work...

let males = people.filter({ $0.gender == .male })

You may need to make your enum conform to equatable to do this comparison.

The $0 is an unnamed parameter, you could also do..

let males = people.filter({ person in return person.gender == .male })

EDIT: I've just tested this and it does work without making the enum conform to equatable. I think you only need to do that when the enum takes parameters.
