Sending SMS in iOS with Swift

Ios Problem Overview

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.

Solution 1 - Ios

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
    }
}

Solution 2 - Ios

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
    }

Solution 3 - Ios

For sending iMessage in Swift 5 I use following code

Just MessageUI package and implement MFMessageComposeViewControllerDelegate

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

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

    @IBAction func sendNewIMessage(_ sender: Any) {
        let messageVC = MFMessageComposeViewController()
        messageVC.body = "Enter a message details here";
        messageVC.recipients = ["recipients_number_here"]
        messageVC.messageComposeDelegate = self
        self.present(messageVC, animated: true, completion: nil)
    }
    
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        switch (result) {
        case .cancelled:
            print("Message was cancelled")
        case .failed:
            print("Message failed")
        case .sent:
            print("Message was sent")
        default:
            return
        }
        dismiss(animated: true, completion: nil)
    }
}

Solution 4 - Ios

Swift 3, 4, 5

@IBAction func sendSmsClick(_ sender: AnyObject) {
        guard MFMessageComposeViewController.canSendText() else {
            return
        }

        let messageVC = MFMessageComposeViewController()
        
        messageVC.body = "Enter a message";
        messageVC.recipients = ["Enter tel-nr"]
        messageVC.messageComposeDelegate = self;
        
        self.present(messageVC, animated: false, completion: nil)
    }
    
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        switch (result.rawValue) {
            case MessageComposeResult.cancelled.rawValue:
            print("Message was cancelled")
            self.dismiss(animated: true, completion: nil)
        case MessageComposeResult.failed.rawValue:
            print("Message failed")
            self.dismiss(animated: true, completion: nil)
        case MessageComposeResult.sent.rawValue:
            print("Message was sent")
            self.dismiss(animated: true, completion: nil)
        default:
            break;
        }
    }

UI will look like:

Solution 5 - Ios

Simpler solution may be opening html link:

let mPhoneNumber = "1111111111";
let mMessage = "hello%20phone";
if let url = URL(string: "sms://" + mPhoneNumber + "&body="+mMessage) {
    UIApplication.shared.open(url)
}

Make sure you replaced spaces with "%20"

Solution 6 - Ios

If you do not want to depend on an UIViewController, follows a Swift 3.0 solution:

import UIKit
import MessageUI

class ECMMessageComposerBuilder: NSObject {

    private dynamic var customWindow: UIWindow?
    private var body: String?
    private var phoneNumber: String?
    fileprivate var messageController: MFMessageComposeViewController?

    var canCompose: Bool {
        return MFMessageComposeViewController.canSendText()
    }

    func body(_ body: String?) -> ECMMessageComposerBuilder {
        self.body = body
        return self
    }

    func phoneNumber(_ phone: String?) -> ECMMessageComposerBuilder {
        self.phoneNumber = phone
        return self
    }

    func build() -> UIViewController? {
        guard canCompose else { return nil }

        messageController = MFMessageComposeViewController()
        messageController?.body = body
        if let phone = phoneNumber {
            messageController?.recipients = [phone]
        }
        messageController?.messageComposeDelegate = self

        return messageController
    }

    func show() {
        customWindow = UIWindow(frame: UIScreen.main.bounds)
        customWindow?.rootViewController = MNViewController()

        // Move it to the top
        let topWindow = UIApplication.shared.windows.last
        customWindow?.windowLevel = (topWindow?.windowLevel ?? 0) + 1

        // and present it
        customWindow?.makeKeyAndVisible()

        if let messageController = build() {
            customWindow?.rootViewController?.present(messageController, animated: true, completion: nil)
        }
    }

    func hide(animated: Bool = true) {
        messageController?.dismiss(animated: animated, completion: nil)
        messageController = nil
        customWindow?.isHidden = true
        customWindow = nil
    }
}

extension ECMMessageComposerBuilder: MFMessageComposeViewControllerDelegate {

    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        controller.dismiss(animated: true, completion: nil)
        hide()
    }
}

You call the composer this way:

let phoneNumber = "987654321"
let composer = MNMessageComposerBuilder()
composer.phoneNumber(phoneNumber).show()

or using a lazy var

let phoneNumber = "987654321"
private lazy var messageComposer: MNMessageComposerBuilder = {
    let composer = MNMessageComposerBuilder()
    return composer
}()
messageComposer.phoneNumber(phoneNumber).show()

Solution 7 - Ios

@IBAction func sendMessageBtnClicked(sender: AnyObject) {
    var messageVC = MFMessageComposeViewController()
    
    messageVC.body = "Enter a message";
    messageVC.recipients = ["Enter tel-nr"]
    messageVC.messageComposeDelegate = self;
    
    self.presentViewController(messageVC, animated: false, completion: nil)
}

func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
    switch (result.value) {
    case MessageComposeResultCancelled.value:
      println("Message was cancelled")
      self.dismissViewControllerAnimated(true, completion: nil)
    case MessageComposeResultFailed.value:
      println("Message failed")
      self.dismissViewControllerAnimated(true, completion: nil)
    case MessageComposeResultSent.value:
      println("Message was sent")
     self.dismissViewControllerAnimated(true, completion: nil)
    default:
      break;
    }
}
