Objective-C Example

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

[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" withItems:@[@{@"amount": @(cur + 2.50)}]];
    }];

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

[socket connect];

Manually (iOS 7+)

Copy the Source folder into your Xcode project. (Make sure you add the files to your target(s))
If you plan on using this from Objective-C, read this on exposing Swift code to Objective-C.

Swift Package Manager

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

import PackageDescription

let package = Package(
    name: "YourSocketIOProject",
    dependencies: [
        .Package(url: "https://github.com/socketio/socket.io-client-swift", majorVersion: 10)
    ]
)

Then import import SocketIO.

Carthage

Add this line to your Cartfile:

github "socketio/socket.io-client-swift" ~> 10.2.0 # Or latest version

Run carthage update --platform ios,macosx.
