What is Delegate Pattern?
The delegate pattern is a core design pattern in iOS where one object delegates responsibility for certain behaviors to another through a protocol. UIKit uses delegation extensively, with UITableViewDelegate, UITextFieldDelegate, and URLSessionDelegate being common examples. Delegates allow customization of behavior without requiring subclassing.
