Socket.IO-Client-Swift

Socket.IO-client for iOS/OS X.

Example

import SocketIO

let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.log(true), .compress])
let socket = manager.defaultSocket

socket.on(clientEvent: .connect) {data, ack in
    print("socket connected")
}

socket.on("currentAmount") {data, ack in
    guard let cur = data[0] as? Double else { return }
    
    socket.emitWithAck("canUpdate", cur).timingOut(after: 0) {data in
        socket.emit("update", ["amount": cur + 2.50])
    }

    ack.with("Got your currentAmount", "dude")
}

socket.connect()

Objective-C Example

@import SocketIO;

NSURL* url = [[NSURL alloc] initWithString:@"http://localhost:8080"];
SocketManager* manager = [[SocketManager alloc] initWithSocketURL:url config:@{@"log": @YES, @"compress": @YES}];
SocketIOClient* socket = manager.defaultSocket;

[socket on:@"connect" callback:^(NSArray* data, SocketAckEmitter* ack) {
    NSLog(@"socket connected");
}];

[socket on:@"currentAmount" callback:^(NSArray* data, SocketAckEmitter* ack) {
    double cur = [[data objectAtIndex:0] floatValue];

    [[socket emitWithAck:@"canUpdate" with:@[@(cur)]] timingOutAfter:0 callback:^(NSArray* data) {
        [socket emit:@"update" with:@[@{@"amount": @(cur + 2.50)}]];
    }];

    [ack with:@[@"Got your currentAmount, ", @"dude"]];
}];

[socket connect];

Swift Package Manager

Add the project as a dependency to your Package.swift:

// swift-tools-version:4.0

import PackageDescription

let package = Package(
    name: "socket.io-test",
    products: [
        .executable(name: "socket.io-test", targets: ["YourTargetName"])
    ],
    dependencies: [
        .package(url: "https://github.com/socketio/socket.io-client-swift", .upToNextMinor(from: "13.0.0"))
    ],
    targets: [
        .target(name: "YourTargetName", dependencies: ["SocketIO"], path: "./Path/To/Your/Sources")
    ]
)

Then import import SocketIO.

Carthage

Add this line to your Cartfile:

github "socketio/socket.io-client-swift" ~> 13.0.0 # Or latest version

Run carthage update --platform ios,macosx.

Add the Starscream and SocketIO frameworks to your projects and follow the usual Carthage process.
