async+

Provides .recover and .catch methods that modularize error handling without nested do/catch blocks, as shown in the README example comparing cleaner chains to verbose native code.

Chains can be converted back to async/await with .async() and .asyncThrows(), ensuring seamless integration with Swift's built-in concurrency system for flexible usage.

Uses distinct Promise<T> and Guarantee<T> types to enforce throwing vs non-throwing chains, preventing unhandled errors with compilation warnings as highlighted in the documentation.

Includes dedicated migration documentation, easing the transition for developers moving existing promise-based codebases to native async/await with chainable patterns.
