映射对象中的值

Question

我的模型看起来像这样：

struct Person {
    let id = 0
    let name = ""
    var comment = String()
}

struct OverAll {
    let person = [Person]
}

我有两个对象：

OverAllPerson // contains 10 persons
OverAlPersonWithComments // contains 10 persons

除了OverAllPerson没有评论

之外，这些对象都是相同的

问题：
如何将OverAlPersonWithComments的评论添加到OverAllPerson？如上所述，除了comments之外，对象是相同的。

我在考虑使用map，但我不知道该怎么做。

Answer 1

对于您的示例，我只是做一个简单的for循环

for index in 0 ..< peopleWithoutComments.count {
    peopleWithoutComments[index].comment = peopleWithComments[index].comment
}

您可能会想到的模式是zip map。考虑：

let names = ["joe", "bill", "jane"]
let comments = [
    ["I like baseball", "But I don't like the Yankees"],
    ["I don't watch sports"],
    ["I like football", "I'm an Arsenal fan"]
]

struct Person {
    let name: String
    let comments: [String]
}

let people = zip(names, comments).map { (name, comments) in Person(name: name, comments: comments) }
