Swift: Get an array of element from an array of tuples

Question

I have an array of tuples like this :

var answers: [(number: Int, good: Bool)] 

I want to get from it an array of number member. Like if I did something like :

answers["number"] // -> Should give [Int] of all values named "number" 

I didn't find anything like it, maybe it's not possible, but it would be sad :(

Answer 1

That's simple:

answers.map { $0.number }
