CloudCoder

Codable support for Encoding and Decoding to CKRecords for storage in CloudKit, with some caveats:

• Unkeyed containers are stored as arrays within the CKRecord
• As such: unkeyed containers (used for Array, Set, etc...) can only store homogeneous primitive types.
• Be careful using Dictionary because the dictionary keys are used to build keys within the CKRecord, so any keys you use must be part of your schema.
• CloudCoder will store nested complex types in Keyed containers (used for struct, class, dictionary, etc...) as snake_case keys beneath the parent type.
• The top-level item being encoded must conform to Identifiable where ID: CustomStringConvertible from which the CKRecord.ID will be derived.

In this example, the CKRecord will have keys: "id", "name", "sub_name", "sub_someValue"

struct Element: Codable, Identifiable {
    var id = UUID
    var name = "My Name"
    var sub: SubElement()
}

struct SubElement: Codable {
    var name = "Other Name"
    var someValue = 42
}

let value = Element()

// Encode
let encoder = CloudRecordEncoder()
let record = try encoder.encode(value)

// Decode
let decoder = CloudRecordDecoder()
let decodedValue = try decoder.decode(Element.self, from: record)
