Apple's iOS 28 schedule shift helps engineers get more creative

Apple has adjusted its approach to developing major operating system updates, allowing engineers more creative freedom in the early stages. This change, observed by Bloomberg's Mark Gurman, shifts the balance in the development cycle to favor more coding time before the integration phase. Traditionally, each major milestone—M1, M2, and M3—has an eight-week structure, with four weeks dedicated to coding and four to convergence, where features are integrated into the OS.

However, for iOS 28 and iPadOS 28, known internally as Bell, Apple has extended the coding phase from four to six weeks, followed by just two weeks of convergence. This change aims to give engineers more time for ideation and experimentation, which they seem to appreciate. The reasoning behind this adjustment is that as the year progresses, integrating features into the operating system becomes more critical, making the early coding phase less rushed and potentially improving the final product's quality.
