缺少Swift 3数组indexOf函数

Question

当我尝试打印包含任何对象的数组的索引时。它没有建议indexOf功能。当我尝试手动输入其显示错误，我已附加截图。

但它正在为String of String工作。有人可以帮我解决这个问题吗？

此外，我正在显示我的代码

import UIKit

class ViewController: UIViewController {

    var arrayOfAnyObject: [Any] = [Any]()
    var arrayOfStringObject: [String] = [String]()

    override func viewDidLoad() {
        super.viewDidLoad()


         print("Index of string object array \(arrayOfStringObject.index(of: "anyString")!)")

         print("Index of any object array \(arrayOfAnyObject.index(of: "anyObject")!)")




        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

您可以在数组中设置所需的类型（Int，String等。）或在执行{arrayOfAnyObject之前将AnyObject转换为indexOf {1}}，像这样：

print("Index of any object array \((arrayOfAnyObject as AnyObject).index(of: "anyObject"))")
