Apple's annual developers conference WWDC returns for 2026 next week, and the company has teased the event with a new "All systems glow" tagline.
"All systems glow" is a play on the phrase "all systems go," and it likely hints at Siri's rumored new design on iOS 27. Both a dedicated Siri app and a new "Search or Ask" feature in the iPhone's Dynamic Island will reportedly have a dark color scheme with glowing elements, as shown in leaked images last week.
Apple's previous tagline for WWDC 2026 was "Coming bright up." That tagline and the graphics for the event all hint at the new Siri design as well.
WWDC 2026 kicks off with Apple's keynote on Monday, June 8 at 10 a.m. Pacific Time. The company is set to unveil iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27, and visionOS 27 on that day, and the conference will run through Friday, June 12, with hundreds of developer sessions to be shared online.
The keynote will be streamed live on Apple.com, in the Apple TV app, and on YouTube.
