I am also seeing this crash. I do not know a fix. For us, the crash started appearing after we made a change to how some of our segues are hooked up. So it seems pretty clear that we caused the regression, but it still only occurs very rarely so we cannot reliably reproduce it.

Yep, same deal. Minimum deployment target is 15.6 and I'm also getting this error.

Ah, I worked around it. You may need to increase the deployment target of all frameworks as well (such as cocoapods). The error logs showed to framework with the dylib issue, so I updated both of their deployment targets and that fixed the crash.
