Apple Shifts Early Development Window for iOS 28 and macOS 28

The company lengthened the first milestone’s coding period to give engineers more time to explore ideas with public betas set for June 2027.

Overview

  • Bloomberg’s Mark Gurman reported on Sunday that Apple changed its M1 milestone from four weeks of coding and four weeks of convergence to six weeks of coding followed by two weeks of convergence.
  • The schedule tweak covers iOS 28, iPadOS 28 (internal codename Bell) and macOS 28 (internal codename Poppy), showing a coordinated shift across Apple’s major OS efforts.
  • Unattributed Apple engineers told Gurman they favor the change because the longer coding window creates extra time for idea development before features are locked.
  • The shorter convergence window keeps each milestone at eight weeks overall but reduces the dedicated integration period, which could alter when and how features are finalized later in the cycle.
  • Gurman said the next milestone was due to begin November 9, Apple has not publicly confirmed the scheduling change, and public betas are expected in June 2027 with a likely release in September 2027.
