I have an array of a struct and I have to modify a property inside the struct whenever user switch between each index of the SegmentControl, for example: // Struct struct User { var name: String var age:Int } // Array var arrayUser = [User(name: "Alex", age: 23] // Modify an array arrayUser[0].age = 19 Will the array create a new copy every time I modify like this or it just reference to that particular element and make a modification? Your response would be highly appreciated :)

I have a problem with moving from parent viewcontroller to a container viewcontroller. My container viewcontroller has a UITableView inside it and whenever I try to switch to it from the parent viewcontroller it always return nil, saying that the UITableView doesn't exist. I know that this problem is probably related to the UITableView is not available yet during the time when I were trying to move into the container viewcontroller. I try to move the setup code into ViewWillAppear but still it doesn't help so I assume this to be a kind of problem where the UITableView is not available yet to show on the screen. Below is my code:     func showSearchAccountVC() {         print("Begin to move into SearchAccountVC")         let searchAccountVC = SearchAccountViewController()                  addChild(searchAccountVC)         self.view.addSubview(searchAccountVC.view)                  searchAccountVC.didMove(toParent: self)         searchAccountVC.view.frame = self.view.bounds     } // MARK: This is in container viewcontroller class SearchAccountViewController: UIViewController {     @IBOutlet weak var searchAccountTableView: UITableView!          override func viewDidLoad() {         super.viewDidLoad()         self.view.backgroundColor = .red         // Do any additional setup after loading the view.         //self.view.backgroundColor = .red         searchAccountTableView.separatorStyle = .none         searchAccountTableView.estimatedRowHeight = 100         searchAccountTableView.rowHeight = UITableView.automaticDimension         searchAccountTableView.delegate = self         searchAccountTableView.dataSource = self     } } Can someone tell me how would I solve this kind of problem? Your response will be highly appreciated!

I need to send data from HomeVC to ResultVC using segue, is this kind of method violate MVC? Inside the ResultVC I created two store properties so that I can access to it in the prepare(for segue: UIStoryboardSegue, sender: Any?) method in HomeVC, can anyone please tell me whether this kind of method violate MVC? Your responses will be highly appreciate! class HomeVC:UIViewController {     override func prepare(for segue: UIStoryboardSegue, sender: Any?) {         if segue.identifier == C.segueToResultVC {             let resultVC = segue.destination as! ResultVC             resultVC.totalSplit = calculator.getSplit()             resultVC.splitInfo  = calculator.splitInformation()         }     } } class ResultVC:UIViewController {     var totalSplit:String?     var splitInfo:String?     override func viewDidLoad() {         super.viewDidLoad()         customizeViews()     }     override func viewWillAppear(_ animated: Bool) {         totalPrice.text = totalSplit         splitAndTip.text = splitInfo     }

I am trying to update my array data and reload the tableview once user click on a cell, however, it takes three hits till the tableview reload a specific row that was selected. This problem only occur when I use (tableview.reloadRows()) but if I use (tableview.reloadData()) everything is working fine with just a single click but I don't want to reload the entire tableview. Can someone please tell me what I did wrong? extension ViewController: UITableViewDataSource, UITableViewDelegate {     func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {         return dummyData.count     }     func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {         let todoCell = tableView.dequeueReusableCell(withIdentifier: "todoCell") as! TodoTableViewCell         todoCell.dataLabel.text = dummyData[indexPath.row].item         if (dummyData[indexPath.row].done == false) {             todoCell.dataLabel.hideStrikeTextLayer()         }else{             todoCell.dataLabel.strikeThroughText()         }         todoCell.delegate = self         return todoCell     }     func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {         let index = IndexPath(row: indexPath.row, section: 0)         if dummyData[indexPath.row].done == false {             dummyData[indexPath.row].done = true             todoTableView.reloadRows(at: [index], with: .none)              }else {             dummyData[indexPath.row].done = false             todoTableView.reloadRows(at: [index], with: .none)         }     } }
