如何将Swift中的数据从NSArray转换为字典？

我需要把NSArray转换成字典，但不知道怎么做

在获取请求后，我已在NSArray中找到结果。这是我的请求：

 var results: NSArray = []

func fetchUpdateAttendee() {
    let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Attendee")
    let predicate = NSPredicate(format: "needUpdate != false")
    fetchRequest.predicate = predicate

    results = try! DBWorker.context.fetch(fetchRequest) as NSArray
    results.forEach { result in
        print(result)
    }

我需要将这些数据放到：let dic4Attendee:[String:Any]=[：]

这是一个核心数据NSManagedObject子类，因此代码应该是

var results = [Attendee]() 


func fetchUpdateAttendee() {
    let fetchRequest = NSFetchRequest<Attendee>(entityName: "Attendee")
    let predicate = NSPredicate(format: "needUpdate == TRUE")
    fetchRequest.predicate = predicate

    do {
        results = try DBWorker.context.fetch(fetchRequest)
        results.forEach { result in
           print(result)
        }
    } catch { print(error) }
}

然后映射数组

let mappedArray = results.map{ $0.dictionaryRepresentation }

我在下面编辑了我的代码。你能在我的代码中写下我应该做什么吗？我更新了答案。您必须将dictionaryRepresentation属性放入Attendee类中。

var dictionaryRepresentation : [String:Any] {
   return ["address" : address,
           "affiliation" : affiliation,
           "city" : city          
            // and so on
          ]
}

let mappedArray = results.map{ $0.dictionaryRepresentation }
