A collection of recommendations and requirements published by Apple, these directives dictate the design and functional behavior of applications intended for the iOS operating system. For example, they specify the appropriate size and placement of interactive elements, the proper use of system fonts, and the standardized animations users expect when navigating within an app.
Adherence to these directives fosters a consistent and intuitive user experience across all applications on the platform. This, in turn, can lead to increased user satisfaction, reduced development time through the utilization of established patterns, and improved app store review approval rates. These standards have evolved significantly since the introduction of the iOS platform, reflecting technological advancements and user interface design trends.
