SwiftProger's questions

请帮我找到最好的实现。给定：具有结构的数组。您需要对特定结构进行更改。

实现非常笨拙，我确信有一些我不知道的东西和一个更优雅的选择

import Foundation

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

var contacts: [Person] = [
    Person(id: 1, name: "Alex"),
    Person(id: 2, name: "Stiv"),
    Person(id: 3, name: "Joy")
]


func renamePerson(id: Int, name: String, array: [Person]) -> [Person] {

    var result: [Person] = []

    for i in array {
        if i.id == id {
            result.append(Person(id: i.id, name: name))
        } else {
            result.append(i)
        }
    }
    return result
}

contacts = renamePerson(id: 1, name: "Sasha", array: contacts)
