Managing Side Effects with Swift

This conference talk from iOS Conf SG explores the critical concept of managing side effects in Swift programming. Learn how functions with side effects—those that depend on or modify external state, like writing data to a database—can create challenges for debugging, testing, reuse, and composition. Speaker Alex Ozun demonstrates various techniques that leverage Swift's expressive type system and powerful runtime to make side effects explicit, controlled, and type-driven. Discover practical approaches to improve your code's maintainability and reliability by properly handling functions that interact with external state.
