CuteBaby can infer Swift models from JSON to save you a lot of time. The tool can infer property's type from JSON, such as String, Int, Double, URL, and Date. You can specify property’s name with Property Map, array’s object name with Array Object Map, property’s type with Property Type Map, or enum's definition with Enum Properties.
It can also handle array root JSON and load JSON from a URL. You can drag and drop text files to create new items. The utility highlights JSON's syntax errors.
