You can place related files in groups, which look like folders. They exist solely as a convenience and don't affect how a project or its targets are built. A group can contain any number of files, frameworks, libraries, and other groups.
Although they look like folders, groups don't necessarily correspond to folders in the file system. Generally, files in a group don't have to be from the same folder. Some special types of groups can't be freely rearranged. One example is the localization group. All the files in this group have the same name, but they're stored in different .lproj
directories in the file system.
