Time
struct Time
extension Time : CustomStringConvertible, Equatable, Hashable
Time represents time in hours and minutes in a 24hr clock.
-
The hour representation of time in a day. (Range is between 0-23).
Declaration
Swift
var hour: UInt { get }
-
The minute representation of time in a 1 hr period. (Range is between 0-59).
Declaration
Swift
var minute: UInt { get }
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Declaration
Swift
static func == (lhs: Time, rhs: Time) -> Bool
Parameters
lhs
A value to compare.
rhs
Another value to compare.
-
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the
String(describing:)
initializer. This initializer works with any type, and uses the customdescription
property for types that conform toCustomStringConvertible
: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 tos
uses thePoint
type’sdescription
property.Declaration
Swift
var description: String { get }
-
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashable
protocol. The components used for hashing must be the same as the components compared in your type’s==
operator implementation. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash(into hasher: inout Hasher)
-
Returns a Boolean value indicating whether two values are not equal.
Inequality is the inverse of equality. For any values
a
andb
,a != b
implies thata == b
isfalse
.This is the default implementation of the not-equal-to operator (
!=
) for any type that conforms toEquatable
.Declaration
Swift
static func != (lhs: Self, rhs: Self) -> Bool
Parameters
lhs
A value to compare.
rhs
Another value to compare.
