Sending SMS in iOS with Swift

First of all, I'm really surprised that this is not a duplicate, because there are TONS of stackoverflow questions that solve this in Objective-C, but I have yet to see a good answer that used Swift.

What I'm looking for is a code snippet in Swift that sends an arbitrary string as a the body of a text message to given phone number. Essentially, I'd like something like this from Apple's official documentation, but in Swift instead of Objective-C.

I imagine this isn't too difficult, as it can be done in just a couple of lines of code in Android.

EDIT: What I'm looking for is 5-20 lines of Swift code, I do not agree that this is too broad. In Java (for Android), the solution looks like this:

package com.company.appname;
import android.app.Activity;
import android.telephony.SmsManager;
public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        public static final mPhoneNumber = "1111111111";
        public static final mMessage = "hello phone";
        SmsManager.getDefault().sendTextMessage(mPhoneNumber, null, mMessage, null, null);
     }
}

Now this is the android solution, and it's only 11 lines. Java tends to be much more verbose than Swift, so I doubt what I'm asking is "too broad", it is more likely that I don't know how to use the Objective-C MessageComposer object, because the documentation that I linked to above is unclear with regard to usage in Swift.

Not sure if you really got the answer. I was in a similar hunt and came across this solution and got it to work.

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

    @IBOutlet weak var phoneNumber: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func sendText(sender: UIButton) {
        if (MFMessageComposeViewController.canSendText()) {
            let controller = MFMessageComposeViewController()
            controller.body = "Message Body"
            controller.recipients = [phoneNumber.text]
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
    }

    func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        //... handle sms screen actions
        self.dismissViewControllerAnimated(true, completion: nil)
    }

    override func viewWillDisappear(animated: Bool) {
        self.navigationController?.navigationBarHidden = false
    }
}

Swift 3.0 Solution:

func sendSMSText(phoneNumber: String) {
        if (MFMessageComposeViewController.canSendText()) {
            let controller = MFMessageComposeViewController()
            controller.body = ""
            controller.recipients = [phoneNumber]
            controller.messageComposeDelegate = self
            self.present(controller, animated: true, completion: nil)
        }
    }

    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        //... handle sms screen actions
        self.dismiss(animated: true, completion: nil)
    }

    override func viewWillDisappear(_ animated: Bool) {
        self.navigationController?.isNavigationBarHidden = false
    }
