将一个结构中的id代码与另一个结构中的字符串值相链接- SwiftUI

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

struct ItemString {
    let id: Int
    let stringValue: String
}

// 假设我们有一个Item数组和一个ItemString数组
let items = [Item(id: 1, name: "Item1"), Item(id: 2, name: "Item2")]
let itemStrings = [ItemString(id: 1, stringValue: "Value1"), ItemString(id: 2, stringValue: "Value2")]

// 创建一个字典来关联id和stringValue
var idToStringValueDict = [Int: String]()
for itemString in itemStrings {
    idToStringValueDict[itemString.id] = itemString.stringValue
}

// 根据Item的id找到对应的stringValue
if let item = items.first(where: { $0.id == 1 }), let stringValue = idToStringValueDict[item.id] {
    print("Item \(item.name) has string value: \(stringValue)")
}

if let item = items.first(where: { $0.id == 3 }), let stringValue = idToStringValueDict[item.id] {
    print("Item \(item.name) has string value: \(stringValue)")
} else {
    print("No string value found for the given id.")
}
