Structure

This is a Swift library meant to be used in mixed-language projects where the codebase still has a considerable amount of Objective-C.

NSResult

This is a simple @objc class that inherits from NSObject and has one single property base: Result<Any, Error>. This property is only accessible on the Swift side, but NSResult can initialized from Objective-C using the following methods:

  • [NSResult success:]
  • [NSResult failure:]

StaticMap

Used on the Swift side to restore type safety to the underlying Result object.

Block

Used on the Objective-C side to cleanly separate the logic for handling a success value from the one for handling a failure.

  • [result performSuccess:^(id _Nonnull value) orFailure:^(NSError * _Nonnull error)]
  • [result performBlock:^(id _Nullable successValue, NSError * _Nullable failureError)]
