MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.

public enum MessagePack { case `nil` case int(Int) case uint(UInt) case bool(Bool) case float(Float) case double(Double) case string(String) case binary([UInt8]) case array([MessagePack]) case map([MessagePack : MessagePack]) case extended(Extended) public struct Extended { public let type: Int8 public let data: [UInt8] public init(type: Int8, data: [UInt8]) { self.type = type self.data = data } } }
You can find this code and more in examples.
let hey = MessagePack("hey there!") let bytes = try MessagePack.encode(hey) let original = String(try MessagePack.decode(bytes: bytes))
let hey = MessagePack("hey there!") let stream = BufferedStream(stream: NetworkStream(socket: client)) try MessagePack.encode(hey, to: stream) try stream.flush() let original = String(try MessagePack.decode(from: stream))
let output = OutputByteStream() var encoder = MessagePackWriter(output) try encoder.encode("one") try encoder.encode(2) try encoder.encode(3.0) let encoded = output.bytes var decoder = MessagePackReader(InputByteStream(encoded)) let string = try decoder.decode(String.self) let int = try decoder.decode(UInt8.self) let double = try decoder.decode(Double.self) print("decoded manually: \(string), \(int), \(double)")
