10 months ago This appears to already be covered in the Macros chapter, which is the appropriate place for this detail anyhow.
Macros are always declared as
public. Because the code that declares a macro is in a different module from code that uses that macro, there isn’t anywhere you could apply a nonpublic macro.

Description
This subsection doesn't reflect the changes to Swift with respect to macros and packages.
Correction
Reword the first sentence in the first paragraph to: Access control restricts access to parts of your code from code in other types, source files, modules and packages. Add the following sentence to the end of the second paragraph: However, both macro declarations and their associated implementation types must have public access since the code that declares a macro is in a different module than that that implements it.
