This refers to a pre-release version of Apple’s operating system intended for use on its mobile devices. Such iterations are typically distributed to developers and public testers before the final, polished release is made available to the general public. These versions allow for real-world testing and feedback gathering before wider deployment.
The implementation of pre-release operating systems is crucial for identifying and resolving bugs, compatibility issues, and performance bottlenecks. Benefits include the opportunity for developers to prepare their applications for the forthcoming operating system, ensuring a smoother transition for end-users. Historically, these programs have significantly improved the stability and user experience of subsequent public releases.
