Including/excluding entire groups from targets
问题 My project has a group with a few hundred files (organized into a couple dozen subgroups two levels deep). The files in that group are themselves being changed reasonably often. I want those files to be included in some targets, but not others. In Xcode 3.x, after each change to the group, I would just Get Info on the group itself, go to the Targets tab, and (re-)select the targets I wanted. (This was, in fact, the answer to a nearly-identical question from 2010, Xcode — groups and targets.)
