how to use socket io in swift - ios

Question

Error :
Blockquote
it says "Argument labels '(String:)' do not match any available overloads"
class SocketIOManager: NSObject {
static let sharedInstance = SocketIOManager()
let socket = SocketIOClient(manager: URL(String:"http://localhost:8080") as! URL, nsp: [.log(true), .forcePolling(true)])
// let socket = SocketIOClient(manager: URL(string: "http://localhost:8080")! as! SocketManagerSpec, nsp: [.log(true), .forcePolling(true)])
override init() {
super.init()
socket.on("test") { dataArray, ack in
print(dataArray)
}
}
How can I solve this.
any help would be apprciated.

Answer 1

I'd recommend you to read through the Socket IO documentation before trying to implement it. To get you started, you need to have a socketClient property in your Socket Manager class and you need to instantiate SocketClient before using Socket events.
class SocketManager {
//Socket IO client instance to emit and observe events of your socket
private let socketClient: SocketIOClient!
private init() {
let socketUrl = "Your Socket URL here"
socketClient = SocketIOClient(socketURL: URL(string: socketURL)!)
setupEvents()
}
func setupEvents() {
socket.on("test") { dataArray, ack in
print(dataArray)
}
}
Hope this helps you get started

I'd recommended below coding:
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()
