推荐答案

这样你就可以从模型类中添加和获取值：

This way you can add and get values from model class:

var user = User(firstName: "abcd", lastName: "efghi", bio: "biodata")
print("\n First name :\( user.firstName) \t Last  name :\( user.lastName) Bio :\( user.bio)")

OutPut将是：

 First name :abcd    Last  name :efghi Bio :biodata

根据您的要求，如果您需要要将对象存储到AppDelegate中的模型类中，则必须创建一个User类型的全局数组，它将存储您的对象，当应用程序加载时，您可以使用以下代码将对象追加到该数组中：

As per your requirement if you want to store object into your model class in AppDelegate then you have to create one global array of type User which will store your objects and when app loads you can append your object into that array with below code:

import UIKit
import CoreData

// Global array
var userData = [User]()

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        let user = User(firstName: "Silviu", lastName: "Pop", bio: "I f**ing ♡ Swift!!!")
        //Add object into userData
        userData.append(user)
        // Override point for customization after application launch.
        return true
    }

}

现在你可以这样访问你的保存对象在 ViewController.swift 类：

Now you can access your save object this way In your ViewController.swift class:

override func viewDidLoad() {
    super.viewDidLoad()
    let user = userData
    println(user[0].firstName)
    println(user[0].lastName)
    println(user[0].bio)

}

而你的OutPut将是：

And your OutPut will be:

Silviu
Pop
I f**ing ♡ Swift!!!
