At 10 AM Pacific on Monday, June 9, 2025, Apple opens WWDC25 in Cupertino, with CEO Tim Cook’s keynote kicking things off. On the eve of the event, Bloomberg’s Mark Gurman used his Power On newsletter, and 9to5Mac followed with details, to lay out the keynote’s headline act: a glassy design language called Liquid Glass, set to become Apple’s biggest visual overhaul in years.
CNBC offered a second frame for the same day: this keynote is about design, not AI. Apple needs an interface that can restart its iPhone upgrade cycle and reverse a battered stock, while its generative AI race keeps going badly.
Gurman confirms the name: Liquid Glass
In his June 8 newsletter, Gurman specifically referenced new “Liquid Glass” UI elements that Apple would show off. As 9to5Mac reads it, that means the new systems will lean heavily on translucent, glass-like materials, with visual details like specular highlights: standard controls such as buttons, toolbars, and tab bars adopt a reflective finish, while home screen app icons get rounder shapes with shiny, highlight-edged borders. Crucially, the language is not iPhone-only — macOS, watchOS, iPadOS, and tvOS will all adopt it, making the software experience consistent across every Apple device. For a company that sells ecosystem consistency, this is a full re-alignment of what its platforms look like.
Why iOS 19 becomes iOS 26
Version numbering is the second focal point: the expected iOS 19 is now expected to ship as iOS 26. Apple is moving to year-based numbering, aligning each platform’s version with the year it will mostly be used in — released in fall 2025, used mainly through 2026. iPadOS, macOS, watchOS, tvOS, and the rest jump to 26 in the same stroke, meaning the number “iOS 19” simply disappears. For developers, this is more than trivia: documentation, tutorials, support matrices, and marketing assets all need their version mappings rewritten.
AI takes a back seat: investors watch the upgrade cycle
Compared with the previous year’s WWDC, which put Apple Intelligence center stage, every preview on June 8 pointed the same way: this year is about design, not AI. CNBC reported that Apple Intelligence lags generative AI offerings from Alphabet, Meta, and OpenAI, and that some inside the company worry the gap poses a future “existential crisis.” What investors want instead is an interface compelling enough to kick-start a new iPhone replacement cycle.
CNBC also framed the stock backdrop: Apple has floundered this year, ceding its crown as the world’s most valuable public company, pressured in part by President Trump’s tariffs. Art Hogan, chief market strategist at B. Riley Wealth, put it bluntly — Apple “has been one of the biggest underperformers of the large cap technology stocks, full stop.” In other words, the market is not looking for flash from this design showcase; it is looking for appeal that converts into shipments. Users, CNBC noted, are still willing to give Apple time, given its track record of polishing features and its massive, loyal device base.
Siri’s status: three upgrades after a hard reset
As for Siri, 9to5Mac rounded up three upgrades coming in iOS 26, centered on personalized assistance. Siri can tap into your other Apple data in a privacy-sensitive way to answer questions: say “play that podcast that Jamie recommended,” and it locates the episode whether it was mentioned in a text or an email; ask “when is Mom’s flight landing?”, and it pulls the flight details and cross-references real-time tracking for an arrival time.
The outlet described Siri as having been in a state of disarray, but improving: new leadership is implementing serious changes, and these bigger upgrades should start reaching users this fall with iOS 26. After the delayed overhaul of Siri and a leadership shake-up, Apple is clearly choosing to ship usable features first.
Three things developers should watch
First, a full UI reskin: Liquid Glass will reach every standard control, so existing app interfaces need rechecking for appearance, contrast, and readability on the new systems — design resources should be inventoried early. Second, the numbering change ripples through tooling: minimum-version checks, documentation naming, screenshots, and store assets all need updating, and external communication should use one consistent story. Third, calibrate AI expectations down: if you were hoping for new models or a blockbuster AI SDK, the June 8 reporting says this keynote is about design consistency. Siri’s personalization features are the visible AI highlight, and the overall pace is far more conservative than the expectations set two years earlier.
