Computed VS Stored Property in iOS Swift 2021
In its simplest form, a stored property is a constant or variable that’s stored as part of an instance of a particular class or structure. Stored properties can be either variable stored properties (introduced by the var keyword) or constant stored properties (introduced by the let keyword).
Computed Property
In addition to stored properties, classes, structures, and enumerations can define computed properties, which don’t actually store a value. Instead, they provide a getter and an optional setter to retrieve and set other properties and values indirectly.
