Properties
Language: Swift
Properties are variables declared within classes or structures. There are three types: instance properties, static properties. There are also lazy properties, which are either instance or static properties, and are only initialized when used. Equivalent to fields in other languages.
Enumerations
Language: Swift
Enumerations are used to group related values together. These values can either be raw or have associated values of primitive types (String, Int, etc.).
Optionals
Language: Swift
In Swift, variables must have a value. Optionals are used to assign a value of nil to a variable, if no value is provided. Optional variables cannot have their values accessed directly. They need to be 'unwrapped' in order for the value to be used.
