The phrase identifies a pre-release software version of Apple’s mobile operating system. The designation “beta” signifies a stage of software development where the software is functional but undergoing testing to identify and resolve any remaining issues before its general release. The numeric values indicate a specific iteration within the development cycle.
These test versions play a critical role in the software development process. They allow developers and a select group of users to experience and evaluate new features, identify bugs, and provide feedback that contributes to a more stable and refined final product. The iterative releases, such as “beta 2,” indicate ongoing refinement based on collected data and user input.
