我正在尝试让我的应用程序调用API，基于用户搜索检索电影信息，然后使用segue将数据传递到下一个视图。在数据应该被传输过来之前，一切似乎都运行良好。我的两个视图控制器和我调用API的文件如下所示。

import UIKit

class ViewController: UIViewController {
    
    @IBOutlet weak var searchBar: UISearchBar!
    
    var movieManager = MovieManager()
    
    var movieTitle = ""
    var movieDescription = ""
    
    var results: [Results] = []
    
    override func viewDidLoad() {
        movieManager.delegate = self
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }
    
}
//MARK: - Movie Manager Methods

extension ViewController: MovieManagerDelegate {
    func didUpdateMovie(title: String?, description: String?, resultsList: [Results]?) {
        movieTitle = title!
        movieDescription = description!
        results = resultsList!
        
        print("\(movieTitle) \n \(movieDescription)")
        
        
    }
    
    func didFailWithError(error: Error) {
        print("error")
    }
    
}
//MARK: - Search Bar Methods
extension ViewController: UISearchBarDelegate {
    
    func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
        movieManager.searchMovie(for: searchBar.text!)
        searchBar.text = ""
        searchBar.resignFirstResponder()
        performSegue(withIdentifier: "goToResults", sender: self)
        
    }
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "goToResults" {
            if let destinationVC = segue.destination as? ResultsListViewController {
                
                destinationVC.movieTitle = self.movieTitle
                
            }
        }
    }
    func searchBarShouldEndEditing(_ searchBar: UISearchBar) -> Bool {
        searchBar.resignFirstResponder()
        return true
    }
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(true)
    }
    
}
