This package offers macros that make destructuring enums with associated values more straightforward.
The @CaseAccessors macro adds computed properties to an enum type that allow easy retrieval of associated values.
@CaseAccessors enum TestEnum {
case stringValue(String)
case intValue(Int)
case boolValue(Bool)
}
let enumValue = TestEnum.string("Hello, Macros!")
if let stringValue = enumValue.stringValue {
print(stringValue) // Prints "Hello, Macros!"
}The second, @CaseConditionals adds boolean computed properties that make it easier to perform conditional checks on enums.
@CaseConditionals enum TestEnum {
case one, two, three
}
let enumValue = TestEnum.one
if enumValue.isOne {
// Do something
}
// The above is equivalent to
if case .one = enumValue {
// Do something
