Still occurs on iOS 18.0 beta 3 (22A5307f).

I find that this achieves the desired behavioral result, but I'm looking for something not using private API: - (id)launchViewController { return nil; }

Problem remains in iOS 18.0 beta 2 (22A5297f). No change. :(

Seems also not fixed in 14.5 beta, from a quick test. I also see the same errors shown above on 14.5 beta.

I’m updating this feedback report to indicate that the problem appears to be fixed with beta 3.

As others have noted, this problem appears to be resolved with beta 3. Prior to updating from beta 2, I had removed the IMAP account. I was able to re-add the account after updating, with the usual warnings about untrusted SSL certificate, and no longer encounter the original error. Mail was able to download my messages, so it seems to be working.

Just to confirm, as others have noted, I still see the same error on beta 2. I also saw "POSIX error 50" once but then the original error code I mentioned above returned after relaunching the Mail app. I've tried re-adding my account, and it did not resolve the issue.

"The virtual controller does not support portrait mode at this time." I think this refers specifically to an iPhone in portrait orientation? On an iPad in portrait orientation it seems to fit fine. Programmatically, how can we determine whether there is enough space to display the virtual controller? Related to this, I am wondering how we can determine the region(s) occupied by the standard virtual controller, in order to avoid having important content obscured by the controls?
