Apple Inc. will kick off its Worldwide Developers Conference (WWDC) on June 9 with an in-person keynote at Apple Park and a weeklong virtual program, where it is expected to unveil major redesigns to iOS, iPadOS, and macOS alongside a long-awaited update on its artificial intelligence efforts.

The event, running through June 13, will spotlight the next iterations of the company's core software platforms-iOS 19, iPadOS 19, and macOS 16-as well as potential announcements related to watchOS, tvOS, and hardware. While the entire conference will be available online, developers and students selected for the in-person experience on June 9 will have access to live sessions, group labs, and one-on-one consultations with Apple engineers.

"We're excited to mark another incredible year of WWDC with our global developer community," said Susan Prescott, Apple's vice president of Worldwide Developer Relations. "We can't wait to share the latest tools and technologies that will empower developers and help them continue to innovate."

One of the most anticipated features is a significant visual redesign across Apple's platforms. Bloomberg's Mark Gurman reported that Apple plans to overhaul icons, menus, and interface elements to unify the user experience across devices.

The company may also offer updates on its AI-powered Siri upgrade, which was announced during last year's WWDC but remains unreleased. The advanced voice assistant was expected to incorporate on-screen awareness, contextual reasoning, and deeper app integration, but Apple has since delayed the rollout.

"It's going to take us longer than we thought to deliver on these features and we anticipate rolling them out in the coming year," Apple spokesperson Jacqueline Roy told Daring Fireball.

The AI delay has led to a team restructure. Gurman reported that Vision Pro executive Mike Rockwell has taken over the project, replacing John Giannandrea. More robust AI features are not expected until iOS 20 "at best," according to sources familiar with Apple's development timeline.

Hardware announcements are also possible. Apple used previous WWDCs to debut the Vision Pro headset and M2-powered Macs. This year, speculation includes refreshed Mac Pro models and second-generation AirTags, both of which Gurman reports could arrive mid-year.

WWDC 2025 will continue Apple's Swift Student Challenge, offering recognition to young developers and inviting 50 Distinguished Winners to Cupertino for a three-day on-site experience. Conference sessions will be available through the Apple Developer app, website, and YouTube channel, with further details to be released in the coming weeks.
