Immutable Types with Changing State in Swift

Read Original

This article discusses the challenge of reconciling immutability with state changes in Swift, a key concept in functional programming. It explains how to design types that produce new instances with updated values rather than mutating existing ones, using a Scorekeeper class example to contrast mutable and immutable approaches. The article provides practical guidance for developers seeking to adopt functional programming principles in Swift, emphasizing the creation of new objects for state transformations.
