How do I make a class conform to a protocol in swift?

Question

I need to make a class conform to a protocol in Swift in order to implement a delegate. How would I do so?

Accepted Answer

```
class YourClass: SuperClassIfAny, FirstProtocol, SecondProtocol {
}
```

Note, though, that some protocols require you to implement delegate methods. For instance, `UITableViewDataSource` requires you to implement

```
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int
```

and

```
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
```

If those are not implemented by the class conforming to the protocol, Xcode will give you a compile error (always check the protocol declaration, Cmd + Click will show you what methods you must implement).
