Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
Macros make the code you see different from the code the compiler sees.
Modern C renders traditional uses of macros for constants and utility
functions unnecessary. Macros should only be used when there is no
other solution available.
