Offending code is in the AppDelegate via the pod XLForms:
section = XLFormSectionDescriptor.formSectionWithTitle("Test Section")section.hidden = false
It crashes when setting hidden to really anything with the same issue:

XLFormSectionDescriptor code is at:
vendor/Pods/XLForm/XLForm/XL/Descriptors/XLFormSectionDescriptor.m
I used the hidden feature tons in 6.2 so I'm surprised it's all of a suddenly an issue.
