我想在我的UITableView中显示一个用户列表。我得到这个错误后，我建立它。
我创建了一个数据模型来存储用户列表。
CRUDSwiftData.swift

import UIKit

class CRUDSwiftData: NSObject {

    var title: String
    var rating: Float
    
    init(title: String,rating: Float) {
        self.title = title
        self.rating = rating
    }
    
}

CRUDSwiftDoc.swift

import UIKit

class CRUDSwiftDoc: NSObject {
   
    var data:CRUDSwiftData
    var thumbImage:UIImage
    var fullImage:UIImage
    
    init(title: String,rating: Float,data:CRUDSwiftData, thumbImage:UIImage, fullImage:UIImage) {
        self.data = CRUDSwiftData(title: title,rating: rating);
        self.thumbImage = thumbImage
        self.fullImage = fullImage
    }
}

然后我把MasterViewController.swift类编辑成这样
MasterViewController.swift

var users: NSMutableArray = []

// At the end of viewDidLoad
self.title = "User List";
 
// Replace the return statement in tableView:numberOfRowsInSection with the following:
return users.count
 
// Replace tableView:cellForRowAtIndexPath with the following
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  UITableViewCell *cell = [tableView
               dequeueReusableCellWithIdentifier:@"MyBasicCell"];
  let user = users[indexPath.row] as CRUDSwiftDoc
  cell.textLabel.text = user.data.title
  cell.imageView.image = user.thumbImage
  return cell;
}

最后我的AppDelegate.swift是这样的
AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
        // Override point for customization after application launch.
        let user1 = CRUDSwiftDoc(title:"Potato Bug", rating: "4", thumbImage: "potatoBugThumb.jpg", fullImage: "potatoBug.jpg")
        let user2 = CRUDSwiftDoc(title:"House Centipede", rating: "3", thumbImage: "centipedeThumb.jpg", fullImage: "centipede.jpg")
        let user3 = CRUDSwiftDoc(title:"Wolf Spider", rating: "5", thumbImage: "wolfSpiderThumb.jpg", fullImage: "wolfSpider.jpg")
        let user4 = CRUDSwiftDoc(title:"Lady Bug", rating: "1", thumbImage: "ladybugThumb.jpg", fullImage: "ladybug.jpg")
        let shoppingList: NSMutableArray[] = [user1, user2, user3, user4]
        
        return true
    }

我在AppDelegate.swift中得到4个错误
