Xcode sets an xattr ("com.apple.XcodeGenerated") on any directories that
will be automatically re-generated when a build is run.  Time Machine
honors that these directories are always re-created for a build, so they
don't need to be backed up.

If you want to keep your old built targets with Time Machine, you'll
have to explicitly move the built *files* outside of that directory
tree, as moving the directories themselves will keep that xattr on the
copy and the contents of those copied directories will not be backed up.
