Hi HN! I've just released SwiftyJSONLine (https://github.com/fumito-ito/SwiftyJSONLines), the better way to deal with JSONLines data in Swift.
It enables you to easily handle `.jsonl` format files, string and data with Swift.
JSON Lines is a convenient format for storing structured data that may be processed one record at a time.
The JSONLines format is also often used as the format for returning batch results in LLM services such as Anthropic Claude and ChatGPT.
