ValueRestriction

What

ValueRestriction is a Swift Package Manager package for iOS/tvOS (10.0 and above), watchOS (4.0 and above), and macOS (10.14 and above), under Swift 5.0 and above, defining an enumeration to easily test a numerical value against some condition:

publicenumValueRestriction<Value>where Value:Comparable{case unrestricted
case equalToOneOf([Value])case notEqualToAnyOf([Value])case smallerThan(Value)case smallerThanOrEqualTo(Value)case largerThan(Value)case largerThanOrEqualTo(Value)case inOpenRange(ClosedRange<Value>)case inOpenClosedRange(ClosedRange<Value>)case inClosedOpenRange(ClosedRange<Value>)case inClosedRange(ClosedRange<Value>)}extensionValueRestriction{publicfunc applied(to value:Value)->Value?publicvarisUnrestricted:BoolpublicvarargumentOfEqualToOneOf:[Value]?publicvarargumentOfNotEqualToAnyOf:[Value]?publicvarargumentOfSmallerThan:Value?publicvarargumentOfSmallerThanOrEqualTo:Value?publicvarargumentOfLargerThan:Value?publicvarargumentOfLargerThanOrEqualTo:Value?publicvarargumentOfInOpenRange:ClosedRange<Value>?publicvarargumentOfInOpenClosedRange:ClosedRange<Value>?publicvarargumentOfInClosedOpenRange:ClosedRange<Value>?publicvarargumentOfInClosedRange:ClosedRange<Value>?}extensionValueRestriction:Equatablewhere Value:Equatable{}extensionValueRestriction:Hashablewhere Value:Hashable{}extensionValueRestriction:Codablewhere Value:Codable{enumCodingKeys:String,CodingKey,CaseIterable{case unrestricted

Installation

ValueRestriction is provided only as a Swift Package Manager package, because I'm moving away from CocoaPods and Carthage, and can be easily installed directly from Xcode.
