ProtocolBuffers for Apple Swift

#Protocol Buffers for Swift

An implementation of Protocol Buffers in Swift.

Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. This project is based on an implementation of Protocol Buffers from Google. See the Google protobuf project for more information.

####Required Protocol Buffers 2.6

How To Install Protobuf

1.ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2.brew install automake

3.brew install libtool

4.brew instal protobuf

5.git clone [email protected]:alexeyxo/protobuf-swift.git

6../scripts/build.sh

7.Add ./src/ProtocolBuffers/ProtocolBuffers.xcodeproj in your project.

Compile ".proto" files.

protoc person.proto --swift_out="./"

Serializing

message Person {
    required int32 id = 1;
    required string name = 2;
    optional string email = 3;
}

let personBuilder = Person.builder()
personBuilder.id = 123
personBuilder.name = "Bob"
personBuilder.email = "[email protected]"
let person = personBuilder.build()
println("\(person)")

person.data() //return [Byte]
person.getNSData() //Return NSData

Deserializing

var person = Person.builder().parseFromData(bytes).build() // from [Byte]

Using Oneof

message SubMessage {
    optional string str = 1;
}

message SampleMessage {
  oneof test_oneof {
     string name = 4;
     int32 id = 5;
     SubMessage mes = 6;
  }
}

var sm = SampleMessage.builder()
sm.name = "Alex"
sm.id = 123
println(ss.build()) //->  id: 123

Nested Types

message SearchResponse {
    message Result {
        required string url = 1;
        optional string title = 2;
        repeated string snippets = 3;
    }
    repeated Result result = 1;
}

var builderResult = SearchResponse.Result.builder()
builderResult.url = "http://protobuf.axo.io"
builderResult.title = "Protocol Bufers Apple Swift"
var searchRespons = SearchResponse.builder()
searchRespons.result += [builderResult.build()]
println(searchRespons.build())
