Question

XCode: Copy Headers: Public vs. Private vs. Project?

That seems to be a good explanation but i still couldn’t understand much of it.

public – readable source code? do they mean readable source code of the header file?

private – since i am still working on that part of the implementation, i’ll mark that header as private and no one will be able to use it, until i change it back to public and build the library again. ??

project – I couldn’t understand anything

Answer 1

Long story short: if you want to make your code available as a library, put those function and type declarations in the header.

If you have complicated code that shares types between c files and requires-forward declaration of types and functions, put them in headers.

Otherwise, no need to use headers. Although it’s nice to separate them out for readibility and documentation purposes.
