UIKit Patterns (Pure UIKit)

This skill covers pure UIKit patterns for building iOS applications. No SwiftUI bridging - all patterns use native UIKit approaches.

State Management (Without SwiftUI)

Delegate Pattern

The classic UIKit approach for communication between components.

// MARK: - Protocol Definition

protocol UserProfileDelegate: AnyObject {
    func userProfileDidUpdate(_ profile: UserProfile)
    func userProfileDidRequestLogout()
    func userProfileDidFail(with error: Error)
}
