How to mail text in swift 4

To send a text message programmatically in Swift 4, you can use the MessageUI framework. Here's a step-by-step guide:

Step 1: Import MessageUI

In your Swift file, add the following line at the top:

import MessageUI

Step 2: Create a MFMessageComposeViewController

Create an instance of MFMessageComposeViewController, which is a view controller that allows the user to compose a text message:

let messageComposer = MFMessageComposeViewController()

Step 3: Set the Recipient and Message

Set the recipient's phone number and the message you want to send:

messageComposer.recipients = ["+1234567890"] // Replace with the recipient's phone number
messageComposer.body = "Hello, this is a test message!" // Replace with your message

Step 4: Present the Message Composer

Present the message composer view controller modally:

present(messageComposer, animated: true, completion: nil)

Step 5: Handle the Message Sent Completion

Implement the messageComposeViewController(_:didFinishWith:) method to handle the message sent completion:

func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
    switch result {
    case.sent:
        print("Message sent successfully!")
    case.failed:
        print("Message failed to send.")
    case.cancelled:
        print("Message composition cancelled.")
    }
    dismiss(animated: true, completion: nil)
}

Step 6: Add the Message Composer to Your View Controller

Add the message composer to your view controller's view hierarchy:

override func viewDidLoad() {
    super.viewDidLoad()
    //...
    if MFMessageComposeViewController.canSendText() {
        let messageComposer = MFMessageComposeViewController()
        // Set the recipient and message
        messageComposer.recipients = ["+1234567890"]
        messageComposer.body = "Hello, this is a test message!"
        // Present the message composer
        present(messageComposer, animated: true, completion: nil)
    }
}

That's it! With these steps, you should be able to send a text message programmatically in Swift 4.

Note: Make sure to add the MessageUI framework to your project's target settings and import it in your Swift file. Also, ensure that the device has a cellular connection or Wi-Fi and that the recipient's phone number is valid.
