BinaryInteger
init(integerLiteral:)

Creates an instance initialized to the specified integer value.

Do not call this initializer directly. Instead, initialize a variable or constant using an integer literal. For example:

  • let x = 23

In this example, the assignment to the x constant calls this integer literal initializer behind the scenes.

value: The value to create.

BinaryInteger
var description: String

A textual representation of this instance.

Instead of accessing this property directly, convert an instance of any type to a string by using the String(describing:) initializer. For example:

  • struct Point: CustomStringConvertible {
  •     let x: Int, y: Int
  •  
  •     var description: String {
  •         return "(\(x), \(y))"
  •     }
  • }
  •  
  • let p = Point(x: 21, y: 30)
  • let s = String(describing: p)
  • print(s)
  • // Prints "(21, 30)"

The conversion of p to a string in the assignment to s uses the Point type's description property.

Declaration

  • var description: String { get }

Instance Methods

func <(_:rhs:) Required

Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument.

This function is the only requirement of the Comparable protocol. The remainder of the relational operator functions are implemented by the standard library for any type that conforms to Comparable.

Parameters: lhs: A value to compare. rhs: Another value to compare.

Declaration

  • func <(lhs: Self, rhs: Self) -> Bool

Declared In

Comparable
func <=(_:rhs:)

Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.

Parameters: lhs: A value to compare. rhs: Another value to compare.

Declaration

  • func <=(lhs: Self, rhs: Self) -> Bool

Declared In

Comparable
func ==(_:rhs:) Required

Returns a Boolean value indicating whether two values are equal.

Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

Parameters: lhs: A value to compare. rhs: Another value to compare.

Declaration

  • func ==(lhs: Self, rhs: Self) -> Bool

Declared In

Equatable
func >(_:rhs:)

Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.

Parameters: lhs: A value to compare. rhs: Another value to compare.

Declaration

  • func >(lhs: Self, rhs: Self) -> Bool

Declared In

Comparable
func >=(_:rhs:)

Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.

Parameters: lhs: A value to compare. rhs: Another value to compare.

Declaration

  • func >=(lhs: Self, rhs: Self) -> Bool

Declared In
