将数据从 Api 传递到数组以在屏幕上显示

您没有在问题中提供数据模型，让我们假设它是，尽管当然CurrentDataData最好重命名它或完全不使用它，立即使用CurrentData

class CurrentData {
    var currentDataData: CurrentDataData?
    
    init?(currentDataData: CurrentDataData?) {
        self.currentDataData = currentDataData
    }
}

struct Employee : Decodable {
    var name: String
    var phone_number: String
    var skills: [String]
}

struct Company : Decodable {
    var name: String
    var employees: [Employee]
}

struct CurrentDataData : Decodable {
    var company: Company
}

我还更正了委托调用，最好在主线程中立即完成

    func fetchCurrentData() {
        let urlString = "https://run.mocky.io/v3/1d1cb4ec-73db-4762-8c4b-0b8aa3cecd4c"
        guard let url = URL(string: urlString) else {return}
        let urlSession = URLSession(configuration: .default)
        let task = urlSession.dataTask(with: url) { data, responce, error in
            if let data = data {
                if let currentData = self.parseJSON(withData: data){
                    DispatchQueue.main.async {
                        self.delegate?.updateInterface(self, with: currentData)
                    }
                }
            }
        }
        
        task.resume()
    }

嗯，控制器中的相应编辑

class MyTableViewController: UITableViewController {

    var data: CurrentDataData?
    let network = NetworkDataManager()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.register(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "Cell")
        tableView.rowHeight = 150
        
        network.delegate = self
        network.fetchCurrentData()

        self.title = "Team of Developer"
    }

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return data?.company.employees.count ?? 0
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! CustomCell
        
        guard let employees = data?.company.employees else {
            return cell
        }
        
        let employee = employees[indexPath.row]
        
        cell.nameLable.text = employee.name
        cell.numbeLable.text = employee.phone_number
        cell.skilsLable.text = employee.skills.joined(separator: ",")
        
        return cell
    }
}

extension MyTableViewController: NetworkDataManagerDelegate{
    func updateInterface(_: NetworkDataManager, with currenData: CurrentData) {
        data = currenData.currentDataData
        tableView.reloadData()
    }
}

同时，这里有一些改进：

• 代替委托，使用闭包，这将简化代码

    func fetchCurrentData(_ completion: @escaping (CurrentData) -> Void) {
        let urlString = "https://run.mocky.io/v3/1d1cb4ec-73db-4762-8c4b-0b8aa3cecd4c"
        guard let url = URL(string: urlString) else {return}
        let urlSession = URLSession(configuration: .default)
        let task = urlSession.dataTask(with: url) { data, responce, error in
            if let data = data {
                if let currentData = self.parseJSON(withData: data){
                    DispatchQueue.main.async {
                        completion(currentData)
                    }
                }
            }
        }
        
        task.resume()
    }

    network.fetchCurrentData {
        self.data = $0.currentDataData
        self.tableView.reloadData()
    }

• 代替直接访问单元中的插座，增加封装并在那里传输数据，并使插座本身成为私有

class CustomCell: UITableViewCell {
    
    @IBOutlet private weak var skilsLable: UILabel!
    @IBOutlet private weak var numbeLable: UILabel!
    @IBOutlet private weak var nameLable: UILabel!
    
    var employee: Employee? {
        didSet {
            skilsLable.text = employee?.name
            numbeLable.text = employee?.phone_number
            nameLable.text = employee?.skills.joined(separator: ",")
        }
    }

}

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! CustomCell
        
        guard let employees = data?.company.employees else {
            return cell
        }
        
        cell.employee = employees[indexPath.row]
        
        return cell
    }
