Extracted from lesson: -----** Let’s start with the method that sets how many rows should appear in the table. Add this code just after the end of viewDidLoad() – if you start typing “numberof” then you can use Xcode’s code completion to do most of the work for you:

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return pictures.count
}

Hi, Xcode does not autio complete when i start typing "numberof". and i scrolled through the list of recommendations when i type "override func tableView" to auto complete the parameters inside the parenthesis, but I dont see any func inside the list that has same argument data type and return value as shown in above code.

Why is it not auto-completing?
