⚡ Why Use Protocols?
- Define shared behavior without inheritance.
- Enable multiple types to conform to the same protocol.
- Protocol extensions provide default implementations.
- Great for clean, flexible, and reusable code.
💡 Tip: Protocols are key to Swift’s powerful and flexible type system. Use them to write modular code!
