Header file can not be found when archiving for Catalyst

[yulin-liang]

Archiving a project for Mac Catalyst that includes the gRPC-Core pod fails because header files in its sub-framework openssl_grpc.framework can not be found. While building for Catalyst or archiving for iOS device are successful.

• When building the project, openssl_grpc.framework creates a new symlink called Header which points to Versions/Current/Headers
  

  

• But archiving doesn't create the symbolic link.
  

  

Here's the BoringSSL-GRPC.podspec, I don't if it is related to the header_mappings_dir or header_dir attributes, do you have any idea?

quick suggestion: did try cocoapods 1.10.1?

[yulin-liang]

It still doesn't work.

#10224 should fix this.
