decodable

问题 I try to parse an api returning a json object.

问题 I'm trying to decode the following JSON in Swift 4: { "token":"RdJY3RuB4BuFdq8pL36w", "permission":"accounts, users", "timout_in":600, "issuer": "Some Corp", "display_name":"John Doe", "device_id":"uuid824fd3c3-0f69-4ee1-979a-e8ab25558421" } The problem is, the last 2 elements ( display_name and device_id ) in the JSON may or may not exist or the elements could be named something entirely different but still unknown, i.e "fred": "worker", "hours" : 8 So what I'm trying to achieve is decode

问题 I have to decode a JSON with a big structure and a lot of nested arrays.

问题 How does the Swift 4 Decodable protocol cope with a dictionary containing a key whose name is not known until runtime? For example: [ { \"categoryName\": \"Trending\", \"Trending\": [ { \"category\": \"Trending\", \"trailerPrice\": \"\", \"isFavourit\": null, \"isWatchlist\": null } ] }, { \"categoryName\": \"Comedy\", \"Comedy\": [ { \"category\": \"Comedy\", \"trailerPrice\": \"\", \"isFavourit\": null, \"isWatchlist\": null } ] } ] Here we have an array of dictionaries; the first has keys
