Apple Reallocates Early Development Time for iOS 28 and macOS 28

The first eight-week milestone now favors six weeks of coding and idea testing over two weeks of integration to give engineers more room to explore before features are locked.

Overview

  • Bloomberg reported the change to the first milestone for iOS 28, iPadOS 28 (codename Bell) and macOS 28 (codename Poppy), moving from a usual four-weeks-coding/four-weeks-convergence split to six weeks of coding and two weeks of convergence.
  • Convergence is the integration window when engineers merge new features into the larger build, and shortening it means more front-loaded time for experimentation but less dedicated time for early integration.
  • The first milestone under the new split has already completed, and the next milestone (M2) was scheduled to begin on Monday, November 9 when teams will start finalizing which features to include.
  • Employees quoted in reports view the change positively because it increases time to develop and test ideas, but Apple has not publicly confirmed the internal schedule adjustment.
  • If the overall release rhythm holds, reporting says iOS 28 should open public beta testing in June and ship in September 2027, and Apple may evaluate whether to apply the new milestone split to later stages based on results.
