Linking

The Link Binary With Libraries build phase in Xcode projects links frameworks and libraries with object files to produce a binary file. Source files that use code in a framework or a library must include a reference to the appropriate programming interface contained in them.

Libraries and frameworks are linked to object files when building an executable file. However, this process is slow and can detract from the development experience. Xcode provides a feature, called ZeroLink, that eliminates the link step while you work on a project; see “Using ZeroLink” for details.
