Variables

Variable Declaration in Swift

Used to declare a variable which holds a value.

Syntax

//implicitly typed
var variableName = value
//explicitly typed
var explicitVariableName: DataType = value

Notes

Variables can be implicitly or explicitly typed. Variables can be changed after values are set.

Variables must either contain a value or nil.

Example

var name = "Anthony"
var length: Integer = 5
