Unwind Segue from Modal/Popover resulting in Unbalanced calls to begin/end appearance transitions

Question

I have the following setup:

Nav Controller -> VC1 -Push--> VC2 -PopOver or Modal Segue--> VC3.

VC3 is unwinding back to VC1.

When the Segue from VC2 to VC3 is PopOver and Modal, the unwind ends in a warning: Unbalanced calls to begin/end appearance transitions for UIViewController"

If the Segue from VC to VC is push, the warning is gone.

Any idea how to get rid of the warning or why its even showing?

Answer 1

It's a bug. Ignore it (or, if you want to be a good citizen, file a bug report with Apple).
