NSNotificationCenter vs Delegation – An Analysis

This article provides a detailed analysis of NSNotificationCenter versus delegation as communication strategies in Swift. It explores questions of expectations, perceived control, impact, and clarity from the perspective of both notifier and listener instances. The author examines what a 'structured environment' means in this context, contrasting the loose coupling of notifications with the more explicit contract of delegates. The analysis helps developers decide which pattern offers greater clarity and structure for their application's architecture.
