dump swift types with resilient superclass failed

[Rokey1990]

What happened?

if specify the IPHONEOS_DEPLOYMENT_TARGET = 13.0, then dump swift types with resilient superclass will be failed! But what is strange is that there is no problem after specifying IPHONEOS_DEPLOYMENT_TARGET to 15.0 or newer.

How can we reproduce this?
