Disfavor deprecated property wrapper inits#522
Merged
Conversation
This change is to make sure that the non-optional generic parameter type is chosen for @argument and @option properties that provide a default value. Previously, an optional type might be chosen depending on how the `help` parameter was spelled, due to strange overload resolution. In particular, using the `.init` caused selection of the deprecated optional overload: // Unexpected: // Infers `Value` as `Optional<AbsolutePath>` @argument(help: .init("The path")) var path = AbsolutePath("/") // Expected: // Infers `Value` as `AbsolutePath` @argument(help: "The path") var path = AbsolutePath("/") This addresses the issue by marking the deprecated overloads as disfavored. rdar://102383455
