Encoding a nested object that does not have nested property in its model

Say I have the following struct:

struct Event: Codable {
    var id: Int
    .... // many non nested fields
}

In my application a user is allowed to create a list of events. Once the user is finished I'd like to pass that list to my server via a POST request.

In order to do so I need to create a valid JSON object that looks like this. This is a list of Event with a leading key of "events".

{ "events": [{"id": 1, ... more of the non nested fields ... },{ ... }]}

How can I setup my Event object in such a way that JSONEncoder.encode(events) will return the expected JSON above? I would really like to avoid having a CodingKey for each field because they encode,decode just fine expect in this circumstance. I'd also like to avoid nesting this Event object inside another struct called Events to get the desired result.

You can just encode a dictionary which associates your events array to the key "events"

JSONEncoder.encode(["events": events])
