Merge arrays with condition

Question

I would like to merge two arrays with specific condition and update objects that they are containing.

First my struct that is in arrays:

struct Item          


        

Answer 1

A solution for your specific problem above would be:

struct Item {
    var id: Int
    var name: String
}

let first = Item(id: 1, name: "Oleg")
let second = Item(id: 2, name: "Olexander")

let firstInSecond = Item(id: 1, name: "Bogdan")
let secondInSecond = Item(id: 2, name: "Max")

let ret = zip([first, second], [firstInSecond, secondInSecond]).map({
    return $0.id == $1.id ? $1 : $0
})

=> But it requires that there are as many items in the first as in the second array - and that they have both the same ids in the same order...
