We cannot find:
/System/Library/Frameworks/PCSC.framework/Versions/Current/PCSC

is this a mistake?
Will it be available in future versions?
Will it get replaced by an alternative?

Thx in advance

It looks like you're trying to find the dynamic library file in the framework using the filesystem (instead of dlopen(3)), this behavior has now changed in Big Sur, see the Release Notes

New in macOS Big Sur 11 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)

I got the same problem on C++ project trying to include headers. With 10.15 it worked. Any suggestions?
