Codable errors are finally readable in Swift 6.3

Swift 6.3 makes DecodingError and EncodingError conform to CustomDebugStringConvertible via SE-0489, replacing the old wall-of-text enum output with a clean one-line summary showing the error case, a plain-English explanation, a dotted coding path (e.g. [0].address.city.birds[1].name), and any underlying error. No code changes are required; the same print(error) call now produces readable output. Two caveats apply: the format is intentionally unspecified so it shouldn't be parsed, and the conformance lives in the standard library so it is not back-deployable to older OS targets even when building with Swift 6.3.
