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
}
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()
Swift 3
@IBAction func sendSmsClick(_ sender: AnyObject) {
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;
}
}
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")
dismiss(animated: true, completion: nil)
case .failed:
print("Message failed")
dismiss(animated: true, completion: nil)
case .sent:
print("Message was sent")
dismiss(animated: true, completion: nil)
default:
break
}
}
}
@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;
}
}
