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

The following code does work independently by the order of the elements inside the 2 arrays

firstArray = firstArray.map { (item) -> Item in
    guard
        let index = secondArray.index(where: { $0.id == item.id })
        else { return item }
    var item = item
    item.name = secondArray[index].name
    return item
}

"[Item(id: 1, name: "Bogdan", value: 3), Item(id: 2, name: "Max", value: 5)]\n"

Update

The following version uses the first(where: method as suggested by Martin R.

firstArray = firstArray.map { item -> Item in
    guard let secondElm = secondArray.first(where: { $0.id == item.id }) else { return item }
    var item = item
    item.name = secondElm.name
    return item
}
