Questions tagged [jsonencoder]

Use this tag for `JSONEncoder` questions on Apple platforms.

JSONEncoder is a class, introduced in Swift 4, for encoding types on Apple operating systems that conform to Encodable protocol (or Codable protocol, which is type alias for Encodable & Decodable). This offers a simple mechanism to easily generate JSON from Encodable Swift types. This applies to standard Swift collections, such as Array and Dictionary, but custom types can conform to Encodable to participate in this simplified JSON encoding process.

This replaces/supplements the JSONSerialiation class used in prior Swift versions.
