MFMailComposeViewController on iOS 10 without Mail app installed?

Now that apps like Apple's "Mail" app can be deleted in iOS 10, what will happen when a developer attempts to initialize and present

and the default Mail app is not installed and configured on the device?

If the app crashes, what is the best way to check for this case?

Answer Source

It looks like MFMailComposeViewController.canSendMail() will return false, and MFMailComposeViewController() will cause a crash (EXC_BAD_ACCESS). Use the canSendMail() check to determine if the device can show a MFMailComposeViewController.
