Apple reportedly gives iOS 28 engineers six weeks to code and two to integrate, Bloomberg says

Apple has reportedly changed how its engineers build the first stage of next year's software, giving developers more room to experiment before features have to be locked in. The shift applies to iOS 28, macOS 28 and the other operating-system updates expected in 2027, according to Bloomberg's Mark Gurman, as relayed by MacRumors. Apple has not commented on the report.

A different split of the schedule

Gurman writes in his Power On newsletter that Apple divides the yearly work on its operating systems into three major stages. Each stage normally runs for four weeks of coding, followed by a four-week "convergence" period in which new features are merged into the shipping builds.

For the first stage of iOS 28, Apple is said to have departed from that pattern. Engineers were reportedly given six weeks to code, explore ideas and build features, followed by only two weeks of convergence. In Gurman's account, employees say they welcome the change because it leaves more time to try out ideas before decisions have to be finalized.

What it does and does not tell us

The report does not name any features planned for iOS 28, and Gurman did not say whether the new split will be repeated for the later development stages. Nothing in it confirms what the update will contain.

The timing follows Apple's usual cadence. Gurman says the software should reach developers in beta in June and be released in September of next year, which matches the pattern of previous major releases.

Part of a wider conversation

The schedule tweak surfaced alongside other Bloomberg reporting this weekend about Apple's software organization. Separate coverage from 9to5Mac, drawing on Bloomberg, describes new CEO John Ternus pressing software chief Craig Federighi to move faster and look beyond incremental improvements to Siri, and says Apple could aim to make Siri behave more like an agent as early as next year. Those items remain unconfirmed reports, and Apple has not discussed them publicly.

As with all pre-announcement reporting, details can change before Apple presents its next software lineup, which it has traditionally done at its developer conference in the summer.
