MFMessageComposeViewController

Sending SMS messages in Swift is very easy. You can add the capability to any app with a few lines of code.

Note: This will not work in the simulator, as the simulator doesn’t support SMS messages!

Step 1: Import MessageIU

Add the following to the top of your ViewController.

import MessageUI

Step 2: Add the Protocol

Add the MFMessageComposeViewControllerDelegate your ViewController definition.

Step 3: Conform to the protocol

Conform to the MFMessageComposeControllerDelegate by adding defining the:

messageComposeViewController:didFinishWithResult method. It might look something like:

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
    switch result.rawValue {
    case MessageComposeResultCancelled.rawValue :
        print("message canceled")
        
    case MessageComposeResultFailed.rawValue :
        print("message failed")
        
    case MessageComposeResultSent.rawValue :
        print("message sent")
        
    default:
        break
    }
    controller.dismissViewControllerAnimated(true, completion: nil)
}
}

You can omit the switch statement. The switch statement provides some feedback to you on the status of the message. Use this to notify your user when a message fails, or is canceled. Or omit if this is unimportant.

Step 3: Open the Message View controller

func sendMessage() {
    let messageVC = MFMessageComposeViewController()
    messageVC.body = "Message string"
    messageVC.recipients = [] // Optionally add some tel numbers
    messageVC.messageComposeDelegate = self
    // Open the SMS View controller
    presentViewController(messageVC, animated: true, completion: nil)
}
