swift uikit swiftui uitableview Swift

I keep running into I'm wondering if anyone has experience with I just started working with I'm facing an issue where my UITableViewCell does not update its content when I change the data source in an iOS 16 app that integrates SwiftUI with UIKit..... I am using a UIViewController that hosts a UITableView, and I have implemented the UITableViewDataSource methods. I've also set up a SwiftUI view that updates a state variable which is supposed to reflect in the UITableView. My data source looks like this: ```swift class MyViewController: UIViewController, UITableViewDataSource { var dataSource: [String] = ["Item 1", "Item 2"] @IBOutlet weak var tableView: UITableView! override func viewDidLoad() { super.viewDidLoad() tableView.dataSource = self } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return dataSource.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier", for: indexPath) cell.textLabel?.text = dataSource[indexPath.row] return cell } func updateDataSource(newData: [String]) { self.dataSource = newData // This is where I expect the table view to refresh tableView.reloadData() } } ``` I call `updateDataSource(newData: ["Item 3", "Item 4"])` when a button in my SwiftUI view is tapped. However, the UITableView does not reflect the updated data; it still shows "Item 1" and "Item 2". I tried calling `tableView.reloadData()` after updating the data source, thinking that would force a refresh of the cells, but it doesn’t seem to have any effect. I’ve also checked for any warnings in the console, and nothing stands out. Is there something I might be missing? Is there a specific way I need to manage the interaction between SwiftUI and UIKit in this scenario? Any insights or best practices would be greatly appreciated. I'd love to hear your thoughts on this. What would be the recommended way to handle this? This issue appeared after updating to Swift 3.9. Am I missing something obvious?
