swift – iOS Xcode 12 _CodeSignature folder not created when generate SDK Framework having Cpp code or information

I am attempting to create SDK framework in xCode12. My code have the cpp file, Goal-c and .swift information

Now, when i attempt to generate the framework and i can construct the mission and it is efficiently construct framework however the “_codesignature” folder isn’t generated so when i am import this framework in different mission it is provides import error.

If i take away .cpp and Goal-c information then i can generate framework with “_codesignature” folder, and in a position to import the framework into different mission efficiently.

So can any please counsel why .cpp information not permit to create “_codesignature” folder when producing framework.
