Hi,

Our App is getting the MFMessageComposeViewController crash and we have no clue in what scenario this would happen. We already use

MFMessageComposeViewController.canSendText()

before launching the message view. Does anyone have any idea?

Hi Eric,

Don't suppose you figured anything out on this? Just started experiencing crashes with similar stack trace after introducing a feature that used MFMessageComposeViewController despite also utilizing the canSendText check. I've been unable to reproduce myself though anecdotally I can add that it only seems to happen once per device and only to a small percentage of the user base utilizing the feature.

Thanks and hope all is well!
