将JSON数据从HTTP请求传递到Swift 3中的另一个视图控制器

func fetchJSONData(completion: @escaping (Result<[String: Any], Error>) -> Void) {
    guard let url = URL(string: "http://example.com/api/data") else {
        completion(.failure(NSError(domain: "Invalid URL", code: 0, userInfo: nil)))
        return
    }
    
    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        if let error = error {
            completion(.failure(error))
            return
        }
        
        guard let data = data else {
            completion(.failure(NSError(domain: "No data received", code: 0, userInfo: nil)))
            return
        }
        
        do {
            let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
            completion(.success(json ?? [:]))
        } catch {
            completion(.failure(error))
        }
    }
    
    task.resume()
}

    super.viewDidLoad()
    
    fetchJSONData { (result) in
        switch result {
        case .success(let json):
            // 在这里处理JSON数据，可以将其传递给另一个视图控制器
            DispatchQueue.main.async {

            }
        case .failure(let error):
            // 处理错误情况
            print("Error: \(error)")
        }
    }
}

func navigateToNextViewController(with json: [String: Any]) {
    // 创建另一个视图控制器，并将JSON数据传递给它
    let nextViewController = NextViewController()
    nextViewController.jsonData = json
    
    // 在这里进行视图控制器的跳转
    // 例如，使用导航控制器进行push或present
    // navigationController?.pushViewController(nextViewController, animated: true)
    // present(nextViewController, animated: true, completion: nil)
