This way you can add and get values from model class:
通过这种方式，您可以从模型类中添加和获取值：
var user = User(firstName: "abcd", lastName: "efghi", bio: "biodata")
print("\n First name :\( user.firstName) \t Last name :\( user.lastName) Bio :\( user.bio)")
OutPut will be:
输出将是：
First name :abcd Last name :efghi Bio :biodata

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:
根据您的要求，如果您想将对象存储到 AppDelegate 中的模型类中，那么您必须创建一个 User 类型的全局数组，该数组将存储您的对象，当应用程序加载时，您可以使用以下代码将您的对象附加到该数组中：
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
}
}
Now you can access your save object this way In your ViewController.swiftclass:
现在您可以通过这种方式访问您的保存对象在您的ViewController.swift课程中：
override func viewDidLoad() {
super.viewDidLoad()
let user = userData
println(user[0].firstName)
println(user[0].lastName)
println(user[0].bio)
}
And your OutPut will be:
你的输出将是：
Silviu
Pop
I f**ing ? Swift!!!
