Loos like MFMailComposeViewController was not created for some reason and thus has nil value. Check if it is nil before presenting it (although this workaround does not answer what went wrong here…). You should also perform the check if mail composer can send mail before trying to create and present it using +canSendMail method (it … Read more

As per Apple, You should check is MFMailComposeViewController are able to send your mail just before sending if ([MFMailComposeViewController canSendMail]) { MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject:@”Test mail”]; [picker setMessageBody:messageBody.text isHTML:YES]; [self presentViewController:picker animated:YES completion:NULL]; } Swift: if MFMailComposeViewController.canSendMail() else { // Send mail code } Ref : Apple Dev … Read more

I have updated it here and it addresses all of the concerns in the comments. import SwiftUI import UIKit import MessageUI struct MailView: UIViewControllerRepresentable { @Environment(\.presentationMode) var presentation @Binding var result: Result<MFMailComposeResult, Error>? class Coordinator: NSObject, MFMailComposeViewControllerDelegate { @Binding var presentation: PresentationMode … Read more
Back again with a new answer. I’m still leaving my previous code up though, because I’m still not convinced that there’s not a way to make use of it. I’ll keep at it myself. The following code DOES work. Mustafa suggests base64 encoding the images, and says that they only work Apple to Apple, but … Read more
Make sure you use controller.mailComposeDelegate = self; and not controller.delegate = self;
Set the UIApplication statusBarStyle in the completion block of presentViewController for your MFMailComposeViewController. i.e. MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init]; [self.navigationController presentViewController:mailVC animated:YES completion:^{ [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; }]; You may also need to add and/or set “View controller-based status bar appearance” to NO in your Info.plist file.
