Yes they are referencing to the build type match the provisioning profile.
So an Ad-Hoc build would be better off have a the iTunesArtwork
and iTunesArtwork @2x
include in the build.
Where as if you are building an AppStore build these icons should not be included.
A solution to do this is make a separate target for AdHoc and include the iTunesArtwork
and iTunesArtwork @2x
in this target only.
