Swift Classes — Everything You Knew About Structs Just Got More Complicated
TL;DR: Explains how Swift classes differ from structs, focusing on five key distinctions. Highlights that classes require explicit initializers and support inheritance, unlike structs.
The article contrasts Swift classes with structs, showing that although they look similar, they behave differently in important ways. Key points include: 1) Classes don’t get a free memberwise initializer and require explicit initializers. 2) Classes support inheritance, letting a subclass inherit properties and methods from a superclass. 3) (implied) Other differences will be covered later in the series. 4) (implied) Practical implications for iOS developers in choosing between the two. 5) The overarching theme is that these differences are not trivial and affect long-term design decisions.
Question for the room: What has been your biggest consideration when choosing between a struct and a class in Swift projects?
