This term refers to a pre-release version of Apple’s mobile operating system, specifically the second iteration of the beta phase for the 18th major release. It signifies a software build intended for testing and evaluation by developers and select users before the final public release. The nomenclature indicates its place within the software development lifecycle, being later in the testing period than the initial beta.
Such early releases are critical for identifying and resolving software defects and compatibility issues. They allow Apple to gather user feedback on new features, interface changes, and overall performance, enabling refinements prior to general distribution. Historically, these beta programs have played a significant role in ensuring the stability and user satisfaction of subsequent full operating system updates.
