A pre-release version of Apple’s mobile operating system is made available to a wider group of users than traditional developer betas. This allows individuals outside of Apple’s internal testing teams and registered developers to experience and evaluate upcoming features and functionalities before the official public release. For example, individuals participating can install this software on their iPhones or iPads to preview changes planned for a forthcoming software update.
This broader testing phase offers significant advantages. It allows for the identification and resolution of software bugs and compatibility issues on a wider range of devices and usage scenarios than would be possible with limited internal testing. Historically, such programs have improved the stability and overall user experience of final software releases by incorporating feedback from a diverse user base. It also gives users an advance look at new features to prepare for upcoming changes.
