Apple has released iOS 26.6 Release Candidate (RC) to developers, marking the final testing phase before the public launch. The update introduces a key feature that prepares iPhones for the upcoming iOS 27, ensuring compatibility and a smooth transition. This release follows the sixth developer beta of iOS 26.6 and comes alongside macOS 26.6 RC, iPadOS 26.6 RC, and iOS 27 Beta 4, all seeded on the same day.

The iOS 26.6 RC is available for registered developers through the Settings app or the Apple Developer Center. The update affects all compatible iPhone models, with iPadOS 26.6 RC covering iPads. The key feature is designed to optimize device performance and storage for iOS 27, which is expected to bring major changes. This matters because it ensures users can upgrade without issues, reducing potential bugs or data loss.

Specific numbers and dates from the source: iOS 26.6 RC was released alongside macOS 26.6 RC, iPadOS 26.6 RC, and iOS 27 Beta 4. The sixth developer beta of iOS 26.6 and macOS 26.6 had been released earlier for testing. The RC is the final version before public release, typically followed by a wide rollout within a week.

Background: Apple has been testing iOS 26.6 through multiple developer betas, with the sixth beta being the most recent before the RC. The company also released iOS 27 Beta 4 simultaneously, indicating parallel development of both operating systems. The RC stage means the software is feature-complete and undergoing final validation.

Likely next steps: The public release of iOS 26.6 is expected soon, possibly within days. Users should install the RC to ensure their devices are ready for iOS 27. Developers can continue testing iOS 27 Beta 4, with further betas likely before the final version. The key feature in iOS 26.6 will facilitate a seamless upgrade path, minimizing disruptions when iOS 27 launches.
