Swift: Declaring a delegate in Struct

I want to declare a delegate in Swift Struct. For example in viewController you can load delegate:

class ViewController : UIViewController, UITableViewDelegate

But in Struct file for example I try to the same :

struct sample:UITableViewDelegate

But I'm getting this error:

Non-Class type 'sample' cannot conform to class protocol NSObjectProtocol

How can I add a delegate to Struct file?

I'll really appreciate your help.

Structs in swift can only conform protocols that not marked as class protocols with keyword class, like CustomStringConvertible protocol

The error says it all. You can't conform to an NSObjectProtocol (father class of all protocols) if you're not a class!

Consider using a vanilla class, if it has to conform to a protocol it should not be a struct at the first place!
