Structs are used almost everywhere in Swift: String
, Int
, Double
, Array
and even Bool
are all implemented as structs, and now you can recognize that a function such as isMultiple(of:)
is really a method belonging to Int
.
Let’s recap what else we learned:
struct
, giving it a name, then placing the struct’s code inside braces.mutating
.didSet
and willSet
property observers to properties inside a struct, which is helpful when we need to be sure that some code is always executed when the property changes.SPONSORED Spend less time managing in-app purchase infrastructure so you can focus on building your app. RevenueCat gives everything you need to easily implement, manage, and analyze in-app purchases and subscriptions without managing servers or writing backend code.
