Apple is changing its software development process for iOS 28 and macOS 28, giving engineers more time to experiment with new features before integrating them into the operating systems. The company has reportedly adjusted its internal development schedule, potentially allowing teams to explore more ideas while maintaining its annual software release cycle.
According to Bloomberg’s Mark Gurman, Apple traditionally divides development of its major operating system updates into three milestones, each consisting of four weeks of coding followed by four weeks of integration and testing.
However, the company has adopted a different schedule for the first development milestone of iOS 28, iPadOS 28, and macOS 28.

Apple Gives Engineers Six Weeks to Develop New Features
Under the revised schedule, Apple’s engineers spent six weeks writing code, exploring ideas, and developing features, followed by just two weeks of convergence, when separate components are integrated into the operating system.
Previously, both phases received four weeks each, meaning Apple has increased the initial development window by 50% without extending the overall eight-week milestone.
Gurman reported that employees have responded positively to the adjustment because it gives them more time to experiment before finalizing their work.
However, the shorter convergence period also leaves less time for integrating features and resolving conflicts between different software components. Apple has yet to confirm whether it will apply the revised schedule to subsequent development milestones.
What This Means for iOS 28 and macOS 28
The changes come as Apple continues expanding its artificial intelligence capabilities across iPhone, iPad, and Mac. The company has already introduced major Siri AI improvements in iOS 27, including conversational interactions and synchronized conversation history.
Gurman previously reported that Apple’s 2027 software releases could be considerably more significant than their predecessors, although specific iOS 28 features remain unconfirmed.
Apple is also reportedly exploring more proactive Siri capabilities that would allow the assistant to complete complex tasks with less user involvement.
The company is expected to unveil iOS 28 and macOS 28 at WWDC in June 2027, followed by public releases later that year.
For now, the revised development schedule suggests Apple wants to give its software teams greater flexibility as it prepares its next major generation of operating systems.
