The structure of iOS is a layered structure and an iOS architect is one who designs this layered architecture, and at the uppermost level iOS works as an intermediary between the underlying hardware and the apps; apps do not interact with the underlying hardware directly.

Lower layers deliver the basic services which all application relies upon and higher-level layer provides sophisticated graphics and interface-related services.
