How to append object multiple time to an array

I try like this:

let heroes = ["abaddon","ember","gondar",etc].map { Hero(name: $0) } 

So I don't need to declare all objects

Why not just

var heroes = [abaddon, ember, ..., wind]

If you want to append multiple objects, You could wrap them into an array themselves and use appendContentsOf.

heroes.append(contentsOf:[abaddon, ember, gondor])
