Swift 中的“故事板不包含标识符为“TimeController”的视图控制器”错误

Question

我正在尝试将 Int 从一个视图控制器快速发送到另一个视图控制器，但出现此错误。关于同一主题还有另一篇文章，但给出的建议是“清理”对我不起作用的项目。这是我的代码：

第一个视图控制器：

import UIKit

class UserInput: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {

    var myInt = Int()

    override func viewDidLoad() {
    super.viewDidLoad()

        myInt = 5

    }

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

    @IBAction func submit(_ sender: Any) {

        let myVC = storyboard?.instantiateViewController(withIdentifier: "TimeController") as! TimeController
        myVC.intPassed = myInt
        navigationController?.pushViewController(myVC, animated: true)
    }
}

第二个视图控制器：

import Foundation
import UIKit

class TimeController: UIViewController {

    var intPassed = Int()

    override func viewDidLoad() {
        super.viewDidLoad()

        print(intPassed)

        }
    }

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

确保您已在情节提要中插入 TimeController 作为情节提要 ID。
