在swift中使用KVC遇到的坑

在Swift4.0之后，类必须要继承自NSObject,同时还需要在属性前面加上@objc
否则会报错

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<test3.Person 0x600000449880> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key name.'

Cannot convert value of type '[String : String]' to expected argument type '[String : AnyObject]'
实例代码：

import UIKit

class Person:NSObject{
    @objc var name:String?

    init(dict:[String:AnyObject]) {
        super.init()
        setValuesForKeys(dict)
    }
}
class ViewController: UIViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        let dict = ["name":"1234"]
        let p1 = Person(dict: dict)
        print("\(p1.name!)")
    }
}

因为我现在在学习swift，这段代码我是参考网上的代码写的，写出来后一直报错，我也不知道怎么办
后来发现是swift的类型变严格了，于是就有下面两种方法

import UIKit

class Person:NSObject{
    @objc var name:String?

    init(dict:[String:Any]) {
        super.init()
        setValuesForKeys(dict)
    }
}
class ViewController: UIViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        let dict = ["name":"1234"]
        let p1 = Person(dict: dict)
        print("\(p1.name!)")
    }
}

import UIKit

class Person:NSObject{
    @objc var name:String?

    init(dict:[String:AnyObject]) {
        super.init()
        setValuesForKeys(dict)
    }
}
class ViewController: UIViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        let dict = ["name":"1234" as AnyObject]
        let p1 = Person(dict: dict)
        print("\(p1.name!)")
    }
}

如果有什么写的不好的地方，希望大家评论区告诉我，毕竟我也才学swift，很多地方都不懂
