Hands-On Design Patterns with Swift

Renaming methods and enum cases

Is is also possible to apply the NS_SWIFT_NAME macro to enum cases as well as class and instance methods:

// A measuring unittypedef NS_ENUM(NSInteger, FVMeasureUnit) {    FVLiters NS_SWIFT_NAME(l),    FVMilliliters NS_SWIFT_NAME(ml),    FVCups,} NS_SWIFT_NAME(MeasureUnit);

Let's also rename one of the static initializers and the conversion method's name to something shorter:

+ (instancetype) withCups:(double) value NS_SWIFT_NAME(init(cups:));- (double) valueInUnit:(FVMeasureUnit) unit NS_SWIFT_NAME(in(unit:));

Notice how you declare an initializer with the init(cups:) syntax; this follows the same conventions as when you specify selectors in Swift.

Now it is possible to use the shorthand enum value when referencing ...
