Prevent execute-file from dump function name by using `strings` and `class-dump`

Question

I am writing a security app in c++. And when I run strings app.name I found there are many method name appear on the result.

Is there any way to hidden these method names? (I can change these function names manually, but I just wonder are there some flags can be added to compiler to hidden these names easily).

Security through obscurity can still be overcome, but you could always strip your binary to remove all the debugging symbols and information.
