The simplest code of Echo Bot looks like this:

main.swift

import Foundation
import Telegrammer

do {
    let bot = try Bot(token: "BOT_TOKEN_HERE")

    let echoHandler = MessageHandler { (update, _) in
        _ = try? update.message?.reply(text: "Hello \(update.message?.from?.firstName ?? "anonymous")", from: bot)
    }

    let dispatcher = Dispatcher(bot: bot)
    dispatcher.add(handler: echoHandler)

    _ = try Updater(bot: bot, dispatcher: dispatcher).startLongpolling().wait()
} catch {
    exit(1)
}
