BinaryChoice

IMPORTANT

2024.04.02: This project has been deprecated.

What

BinaryChoice 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 protocols for types that can be initialised from a boolean value and/or can be represented by a boolean value:

/// A protocol to represent types that have a boolean representation.
///
public protocol BooleanConvertible {
    var booleanDescription: Bool { get }
}

/// A protocol to represent types that can be initialized from a boolean value.
///
public protocol InitializableByBoolean {
    init(_ value: Bool)
}

/// A protocol to represent types having only two values, which can then be
/// mapped to *true* and *false* in a one-to-one fashion, in both directions.
///
public protocol BinaryChoice: InitializableByBoolean, BooleanConvertible {}

/// The Bool type has a natural conformance to *BinaryChoice*.
///
extension Bool: BinaryChoice {

    /// Returns *self*.
    public var booleanDescription: Bool { self }

}

Installation

BinaryChoice 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.
