Resilient Decoding in Swift

Airbnb:

This package defines mechanisms to partially recover from errors when decoding Decodable types. It also aims to provide an ergonomic API for inspecting decoding errors during development and reporting them in production.

[…]

After running this code, foo will be a Foo where foo.array == [1, 3] and foo.value == nil. In DEBUG, foo.$array.results will be [.success(1), .failure(DecodingError.dataCorrupted(…), .success(3)] and foo.$value.error will be DecodingError.dataCorrupted(…). This functionality is DEBUG-only so that we can maintain no overhead in release builds.

Cool use of Swift property wrappers and projected values.
