From Siri Overhaul To Design Changes, Everything We Know About iOS 27 Ahead Of WWDC 2026

Hyderabad: Apple is set to unveil iOS 27 at its annual developer conference, Worldwide Developer Conference (WWDC), scheduled to take place from June 8 to June 12, 2026. This will be Tim Cook's last developer conference as the Apple CEO, as he is set to step down from his post on September 1, 2026, making way for John Ternus, who is currently the company's senior vice president of Hardware Engineering.

At the WWDC 2026, Apple will unveil the next generation of software for its devices, including the new iOS update for iPhones. Notably, the upcoming iOS 27 will be rolled out alongside the anticipated iPhone 18 Series in September 2026.

While Apple has yet to officially announce the iOS 27 operating system (OS) for iPhones, several reports offer a fairly detailed picture of what to expect. So, here's everything we know about iOS 27 so far.

Which iPhones Will Run iOS 27?

As with every annual update, iOS 27 will drop support for older devices. Reports suggest that the iPhone 11 lineup — including the Pro and Pro Max variants — along with the second-generation iPhone SE, will be phased out. In short, any device older than an iPhone 12 is unlikely to run iOS 27. Meanwhile, Apple Intelligence remains restricted to the iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16, and newer models.

A New-Look Siri Leads The Charge

The main highlight of iOS 27 is an AI-powered overhaul of Siri, something that has been in the works for a long time, following a series of internal delays. The revamped voice assistant is expected to function as a full-fledged AI chatbot with its own standalone app. It is anticipated to incorporate on-screen content, personal context, and cross-app actions into its responses. The overhauled Siri will be powered primarily by Google's Gemini model, though users, according to several reports, will be able to swap in third-party AI models if preferred.

According to Bloomberg's Mark Gurman, Siri can still be triggered via wake word or the power button, but a new interface will be embedded into the iPhone's Dynamic Island. Swiping down from the top of the screen will open query input, with an additional swipe taking users directly into the chatbot interface. Gurman also reports that Photos will gain the ability to add generative AI elements to existing images, while Camera users will be able to instantly reverse image search a photo on Google.

Apple Intelligence gets new features

Beyond Siri, several existing Apple Intelligence tools are expected to be in line for upgrades. Image Playground and Genmoji are likely to see significant improvements to image quality, and a new feature could allow users to generate custom AI wallpapers for their home screens. Writing Tools is also expected to receive an upgrade, with better detection of syntax errors rather than just basic spelling mistakes. Users would additionally be able to create custom app shortcuts using natural language prompts through Siri.

App Updates And Liquid Glass

On the design front, Apple is not expected to make major changes to the Liquid Glass language introduced in iOS 26. Although a few additional customisation options may be introduced. At the app level, the Camera could gain support for custom widgets, Weather is likely to receive a new Conditions panel, and the Wallet app is expected to debut a "Create a Pass" feature that can scan physical tickets and memberships to generate digital versions.
