A straightforward reference for working with Swift's Codable protocol, covering everything from automatic synthesis to manual implementations with nested containers. The decision tree at the top is genuinely useful for quickly figuring out which approach you need based on your specific constraints. It handles the common cases like custom CodingKeys for mismatched property names, but also gets into the trickier scenarios like enums with associated values and structural transformations. If you're regularly switching between projects or onboarding developers who need to get Codable patterns right without digging through Apple's docs every time, this consolidates the patterns in one place. Nearly 1,000 stars suggests it's resonating with the Swift community.
