Swift defines enumerations and struct bodies and uses

Defining enumerations

Enum Mapdirection {

Case North

Case South

Case East

Case West

Func simpledescription (), String {

Switch Self {

Case. North:

Return "North"

Case. South:

Return "South"

Case. East:

Return "East"

Case. West:

Return "West"

}

}

}

Using enumerations

Let en:mapdirection = Mapdirection.north

var en = Mapdirection.north

Print (En.simpledescription ())

En =. West

Print (En.simpledescription ())

Define Structure body

struct Summation {

var addend:int

var augend:int

var addstring:string

var augstring:string

Func sum (), Int {

return addend + augend

}

Func sumstring (), String {

return addstring + augstring

}

}

Create a struct body

Let newstruct = summation (addend:10, augend:20)

Let newstruct = summation (Addend:10, augend:20, addstring: "Newstruct", augstring: "Newstruct")

Using methods in the structure body

Let sum = Newstruct.sum ()

Print (sum)

Print (newstruct.sumstring ())
