Apple Shifts Early iOS 28 and macOS 28 Development Timeline

The change moves two weeks from integration into coding to give engineers more time to experiment while compressing later integration windows.

Overview

  • Bloomberg’s Mark Gurman reported that Apple altered the first eight-week milestone for its next OS cycle to six weeks of coding and two weeks of convergence, instead of the usual four-and-four split.
  • The adjustment reportedly applies to iOS 28 and iPadOS 28 (internally ‘Bell’) and macOS 28 (internally ‘Poppy’), and employees told Gurman they welcome the extra time for idea development.
  • Gurman says the M1 stage using the new split has completed and the next milestone to begin finalizing which features ship was scheduled to start Monday, November 9.
  • Apple has not publicly confirmed the schedule change and no specific iOS 28 or macOS 28 features were disclosed in the reporting, though public beta and full-release windows remain projected for June and September next year.
  • Shifting time into early coding could improve feature creativity and quality but may increase pressure during later convergence and testing phases, a trade-off Apple will need to manage across the rest of the M2 and M3 milestones.
