create a new message view in swift

To create a new message view in Swift, you can use the MessageUI framework provided by Apple. This framework provides classes for presenting standard view controllers for sending emails and text messages.

1. Start by importing the MessageUI framework in your view controller file:

main.swift
import MessageUI
17 chars
2 lines

2. Next, extend your view controller to conform to the MFMessageComposeViewControllerDelegate protocol. This will allow you to handle the callback when the user has completed sending the message or cancelled the message compose view.

main.swift
class MyViewController: UIViewController, MFMessageComposeViewControllerDelegate {
  // ...
}
94 chars
4 lines

3. When you're ready to present the message compose view, create an instance of MFMessageComposeViewController and set the desired properties, such as the message body and recipients:

main.swift
let messageComposeVC = MFMessageComposeViewController()
messageComposeVC.messageComposeDelegate = self // set the delegate to handle message sending callbacks
messageComposeVC.recipients = ["1234567890"] // set the recipients of the message
messageComposeVC.body = "Hello, world!" // set the body of the message
312 chars
5 lines

4. Lastly, present the message compose view using present(_:animated:completion:):

main.swift
if MFMessageComposeViewController.canSendText() {
  self.present(messageComposeVC, animated: true, completion: nil)
}
118 chars
4 lines

Make sure to check if canSendText() is true before presenting the message compose view, as this will ensure that the user's device is capable of sending text messages.

That's it! You now have a new message view in your Swift app.
