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

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

socket.on("currentAmount") {data, ack in
    if let cur = data[0] as? Double {
        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"];
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" with:@[@{@"amount": @(cur + 2.50)}]];
    }];

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

[socket connect];
