8.4    Computed Properties

In the previous chapter, you learned about computed properties for enumerations, remember? Structs feature computed properties in nearly the same way. Based on existing properties of a struct, you can compute new values when requested by the caller. Likewise, you can accept a computed value from the caller to interpret and break down into real properties. In this section, you will see examples of both.

8.4.1    Getters

This is going to be a familiar topic, similar to enumerations—so expect an easy ride! In a struct, a getter is a computed property that computes and returns a value based on existing properties. In Listing 8.12, isDead is a getter of the Monster struct.

struct Monster {    @MainActor    static var isPaused ...
