Swift Naming conventions

Swift can use almost any character as a constant and variable name, including Unicode, but cannot contain number symbols, arrows, invalid Unicode, horizontal lines-tabs, and cannot begin with a number.

var π= 3.14

var new air software = " development software "

Let's hello = " Hello World "

The form of shaping

Binary: Prefix 0b

Octal: Prefix 0o

Hex: Prefix 0x

Let decimalinteger =

Let binaryinteger = 0b10001

Let octalinterger = 0o21

Let hexadecimlinteger = 0x11

Let minValue = UInt8. Min

Let maxValue = UInt8. Max

UInt8 is a struct struct

{

Public struct UInt8: unsignedintegertype, comparable, equatable {

public var value:builtin. Int8

// A type that can represent the number of steps between pairs of

// values.

public typealias Distance = Int

// Create An instance initialized to zero.

public init()

// Create An instance initialized to ' value '.

public Init(_ value: UInt8)

public init(_builtinintegerliteral value:builtin. Int2048)

// Create An instance initialized to ' value '.

public init(integerliteral value: UInt8)

public static var max: UInt8 {get}

public static var min: UInt8 {get}

}

type aliases

Typealias Nsinteger = Int

var value: nsinteger =

Value =

Print(value)

Boolean type

var tigerisanimal: Bool = true
