Type 'ViewController' does not conform to protocol 'UITableViewDataSource'

Question

Started practice swift. In singleViewController I am trying to make a UITableView. In storyboard I set the datasource and delegate. Here I am getting the error

Just a suggestion to improve readability, you can separate your protocols using extension, like this:

class ViewController: UIViewController {
    // Your lifecycle code here
}

extension ViewController: UITableDataSource { 
    func tableView(tableView:UITableView!, numberOfRowsInSection section:Int) -> Int {
         return 20
    }
}

extension ViewController: UITableViewDelegate {
    ...
}
