Swift encourages developers to prefer value types.
So when should you actually use a class?
Classes become useful when your model needs:
- Reference semantics
- Identity
- Shared mutable state
- Inheritance
- A shared lifecycle
The important part isn't memorizing the differences between struct and class.
It's understanding why reference semantics are sometimes necessary.
In this guide, I explore Swift classes, reference types, inheritance, and the situations where a class is the better design choice.
