Page Summary
-
DayOfWeekis an enumeration representing the days of the week. -
It conforms to
Equatable,Hashable, andRawRepresentableprotocols, allowing for comparison, hashing, and raw value representation. -
Each day of the week (Monday through Sunday) is represented by a distinct case within the enumeration.
-
The raw value of each case is a
UIntand aligns withNSDateComponents.weekdayindex (refer to the provided Apple documentation link for details). -
An initializer
init(rawValue:)is available to create an instance ofDayOfWeekfrom a raw value.

The raw type that can be used to represent all values of the conforming type.
Every distinct value of the conforming type has a corresponding unique value of the
RawValuetype, but there may be values of theRawValuetype that don’t have a corresponding value of the conforming type.Declaration

Swift
case friday -
Creates a new instance with the specified raw value.
If there is no value of the type that corresponds with the specified raw value, this initializer returns
nil. For example:enum PaperSize : String { case A4 , A5 , Letter , Legal } print ( PaperSize ( rawValue : "Legal" )) // Prints "Optional(PaperSize.Legal)" print ( PaperSize ( rawValue : "Tabloid" )) // Prints "nil"Declaration
Swift
init ?( rawValue : UInt )Parameters
rawValueThe raw value to use for the new instance.

Declaration
Swift
case monday -
The corresponding value of the raw type.
A new instance initialized with
rawValuewill be equivalent to this instance. For example:enum PaperSize : String { case A4 , A5 , Letter , Legal } let selectedSize = PaperSize . Letter print ( selectedSize . rawValue ) // Prints "Letter" print ( selectedSize == PaperSize ( rawValue : selectedSize . rawValue ) ! ) // Prints "true"Declaration
