Solution

whereis probably works just fine, there are just no binaries named Notes or XCode in your $PATH. For confirmation, please try to run which Notes and which XCode. Also try whereis man to confirm that whereis is actually working.

XCode and Notes come as App bundle and their executables are not placed in the "normal" places like /usr/bin. Instead their executable is inside their bundle directory, which (or rather the appropriate subdirectory) is usually not part of $PATH. For Notes this the bundle directory is /Applications/Notes.app and the executable is /Applications/Notes.app/Contents/MacOS/Notes.
