- 
          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.DeclarationSwift typealias RawValue = UInt

                  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"DeclarationSwift init?(rawValue: UInt)ParametersrawValueThe raw value to use for the new instance.

                  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"DeclarationSwift var rawValue: UInt { get }
