I make a demo with UISearchController，run with debug mode and reproduce the problem，I get the crash info:
objc[10097]: Cannot form weak reference to instance (0x10c063a00) of class _UIRemoteInputViewController. It is possible that this object was over-released, or is in the process of deallocation.
When I run the app without debug, the crash info is the same as jieunYoo's full crash report.
