Sending a text

In route handler

import Twilio

func routes(_ app: Application) throws {
    app.get { req -> EventLoopFuture<ClientResponse> in
        let sms = OutgoingSMS(body: "Hey There", from: "+18316100806", to: "+14083688346")
        return req.twilio.send(sms)
    }
}

Anywhere else

import Twilio

public func configure(_ app: Application) throws {
    // ...
    // e.g. in the very end
    let sms = OutgoingSMS(body: "Hey There", from: "+18316100806", to: "+14083688346")
    app.twilio.send(sms).whenSuccess { response in
        print("just sent: \(response)")
    }
}

Handling Incoming Texts

After setting up the necessary routing within your Twilio account, you may create routes to handle and respond to incoming texts.

import Twilio

func routes(_ app: Application) throws {
    app.post("incoming") { req -> Response in
        let sms = try req.content.decode(IncomingSMS.self)

        let responseMessage = SMSResponse(
            Message(body: "Hello Friend!"),
            Message(body: "This is a second text.")
        )

        return req.twilio.respond(with: responseMessage)
    }
}
