Classes and structures
Classes and structures are general-purpose, flexible constructs that become the building blocks of a program's code. They have the following features:
- Properties can be defined to store values
- Methods can be defined to provide functionality
- Subscripts can be defined to provide access to their values using subscript syntax
- Initializers can be defined to set up their functionality beyond a default implementation
- They can conform to protocols to provide standard functionality of certain kinds
