Protocols not been implemented...? Help!

App Development

I have being doing the exercises, and did the worksheet (module3 lesson 5) on Protocols & Delegates, but I got stuck!!! Please help. Xcode tells me that ViewController is not conforming to the protocol.
(I thought I did…)

Here is what my worksheet looks like… What am I missing / doing wrong? HELP PLEASE

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

@IBOutlet weak var myTableView: UITableView!

let dataArray = ["bird","dog","cat","turtle","bear"]

override func viewDidLoad() {
    super.viewDidLoad()
    
    myTableView.delegate = self
    myTableView.dataSource = self
    
    // MARK: UITableView Protocol Method IMPLEMENTATION
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return dataArray.count
        
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
    //Get the data for this row
    let rowData = dataArray[indexPath.row]
    
    //Get a cell to display
    let cell = tableView.dequeueReusableCell(withIdentifier: "BasicCell", for: indexPath)
        
   cell.textLabel?.text = rowData
        
    //Return the cell
    return cell
    }
    
}

}

You are missing a closing brace for your viewDidLoad() function so the compiler can’t see the two tableView protocol methods because they are technically inside viewDidLoad().

Roosterboy is right there is no closing bracket below the mytableview.datasource to close off viewdidload
