ios - 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?

Answer 1

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).
