NSNotificationCenter vs Delegation – An Analysis

This article provides an in-depth analysis comparing NSNotificationCenter and delegation as communication strategies in Swift. The author explores questions of expectations, perceived control, impact, and clarity from the perspective of notifier and listener instances. It examines how each strategy affects code structure, traceability, and developer understanding, arguing that delegation offers a more structured environment for instance-to-instance communication. The analysis is technical and relevant for iOS/macOS developers evaluating design patterns.
