Pick a Delegate… Any Delegate… On Clean View Controllers in Swift

This article discusses the delegation pattern in iOS development, focusing on the common practice of overloading View Controllers with delegate responsibilities. The author presents a cleaner approach by creating a separate EmailComposer class to handle MFMailComposeViewController configuration and delegate methods, reducing View Controller complexity. A fully-working example is provided on GitHub, and the article evaluates the benefits of this refactoring technique for iOS Swift developers.
