Apple starts development work on 2025 OS releases

A new report says that Apple has formally begun work on the OS updates planned for late 2025, including macOS, iOS, watchOS, and visionOS.

In a typical move, Apple is wrapping up its foundational work on 2024's forthcoming software releases, and focusing on the year ahead. Betas for iOS and iPadOS 18, watchOS 11, and macOS 15 Sequoia are already in the hands of developers now.

Those OS updates, already teased during the WWDC conference, will be out in the fall of 2024. According to a report from Bloomberg, Apple's engineers have started turning engineering attention to the releases for late 2025, including iOS 19, watchOS 12, macOS 16, and visionOS 3.

Each of these future releases has a codename. The iOS 19 version in testing has reportedly been dubbed "Luck," while macOS 16 is called "Cheer."

The codename "Nepali" has been given to watchOS 12, while visionOS 3 is said to be called "Discovery."

The traditional reason for starting work on these OS revisions so early is so that the company can coordinate software with future hardware products already in development. And, this is not an accelerated timeline — it is consistent with previous years.

In addition to expected new models of iPhone, iPad, and Mac to be unveiled later in 2024, other products are anticipated for release in 2025. This is expected to include a lower-cost, lower-spec version of the Apple Vision Pro, which might simply be called "Apple Vision."

Other rumors for 2025 have speculated on a refreshed Apple TV box, and long-awaited updates to the Mac Pro and Mac Studio. The pro-level Macs will see updated specs that allow for expected M4 Pro, M4 Max, and a possible M4 Ultra variant.

So, the same developers have time to work on version 19 when 18 is not even out to the public yet????

Yes, that's right.

Think of it this way: a reporter writes a news story at midnight. An editor checks it over for errors, makes corrections, and passes it on to the press room. The newspaper is published and delivered in the wee hours, and you read it over your morning coffee.

The core development team's work on iOS 18 (v1) is done. The people inside and outside Apple testing it and fixing problems are the editors. Now the reporters start work on tomorrow's stories.

Apple is always working on things years in advance. It's not like they're JUST starting to work on the next revisions of any OS for 2025. They were most likely working on those months ago even if it was just planning things out, and even while working on the current and upcoming OS's in the fall. Otherwise they won't be able to sustain releasing a new OS every year.

It's your basic project management, where engineering resources often work on multiple iterations of products during multiple stages of its lifecycle.

Apple likely has a core team of people who work on the foundational aspects of their platforms, which apply to all of them. There will be a XNU core OS team and foundational OS userland teams (APIs, networking, etc) that will roll into production across all of the platforms, and they will work on multiple versions at the same time. There is likely a set of people working the platform release 3 to 4 years out let alone next year.

Then, there will be the platform specialist teams, who program the various user-facing features of each platform. They also will work on multiple iterations of the products at the same time.

There will be a resources concentration for when platforms get into production. A vast majority of Apple's software engineering resources were likely working on getting the current betas out the door from March to June. Now that the initial betas are out and cycling in public, the amount of people working on them has likely decreased a lot and they are working on 2025 platforms while there is a smaller production team trying to get the 2024 OS platforms to release in September.

"Beta" means the 2024 releases are feature complete, and they are getting the bugs out. If they can't get all features into the initial release, they obviously push those features into a later point release.
