Siri 2.0 at WWDC 2026: What iOS Developers Need to Know

Apple’s WWDC 2026 keynote is Monday morning. Under the theme “All systems glow,” the company is ready to ship what Bloomberg calls its “AI turnaround” — Siri 2.0, a ground-up redesign of the voice assistant arriving with iOS 27 and Apple’s first serious attempt to compete with ChatGPT and Gemini on the phone.

The pressure Apple is carrying into this keynote

Apple settled a $250 million lawsuit earlier this year after users argued the company had advertised Siri features — contextual awareness, cross-app actions, on-screen intelligence — that never shipped. The settlement was not an admission of fault, but the optics were damaging. WWDC 2026 is not a routine software update cycle. It is a credibility event.

Monday is also expected to be Tim Cook’s final WWDC keynote as CEO. Cook navigated Apple from the iPhone’s peak into services and wearables, but AI has been the platform’s visible weak point throughout his tenure. Whatever comes next for Apple’s leadership inherits either a recovered AI story or a compounding problem. The decisions made about APIs and frameworks this week tend to stick for years.

What Siri 2.0 looks like

Leaked renders published by Bloomberg and corroborated by The Verge show a Siri that is unrecognizable from the current voice overlay. The redesign introduces a standalone chat application — built on Liquid Glass, Apple’s new design language — with a persistent conversation thread and a Dynamic Island component that surfaces Siri’s responses without opening the full interface.

The chat-first model is not a surprise given where the industry has gone. What is notable is the architectural choice to embed Siri 2.0 directly in the Dynamic Island: instead of interrupting the screen, conversational context appears as a live activity-style pill that expands on tap. For users, it is less disruptive. For developers, it is a meaningful new surface that can reference your app’s real-time data.

Per TechRadar’s leaked details, the new interface supports multi-turn queries — follow-up questions that carry context from the previous turn, similar to how ChatGPT maintains a thread. This is a fundamental shift from the stateless, single-shot model Siri has used since 2011.

What changes for App Intents

Siri 2.0’s usefulness scales directly with how thoroughly developers have implemented App Intents. This has been true since Apple introduced the framework in iOS 16; the difference now is that a chat-capable Siri can chain intents across apps in multiple conversational turns in ways the single-shot voice model could not sustain.

Practically, three things will matter when iOS 27 developer beta 1 drops Monday afternoon:

• Entity resolution: if your intent exposes a typed list — a user’s saved items, a shopping cart, a project — Siri can now reference those entities by name across follow-up queries. Undeclared entities mean Siri has nothing to reason over.
• Parameter metadata: the @Parameter display names, synonyms, and summary fields you provide will appear directly in the Siri chat UI. Sparse parameter declarations were forgivable in a voice-only world; in a chat interface they surface as blank or generic responses.
• Dynamic Island state: the leaked architecture suggests Siri 2.0 can read Live Activity state from the Island when answering queries about an active session. If your app already surfaces real-time data there, that data becomes Siri-queryable without additional work.

Read the App Intents framework diff before anything else on Monday afternoon. That is where the actual capability surface will be defined, independent of the keynote narrative.

The privacy architecture Apple has not resolved

Apple’s competitive positioning against OpenAI and Google rests on two pillars: on-device inference and Private Cloud Compute. Siri does not need to see your data to help you — or so the argument goes.

Siri 2.0’s persistent chat thread creates real friction with that position. A conversation history means context is stored somewhere. Frandroid reports that Apple is building a deliberate memory-forgetting mechanism — a way for Siri to discard session context at the user’s direction, or automatically after a session ends. That is the privacy answer.

It is also a capability ceiling. A Siri that forgets Tuesday’s conversation is meaningfully less useful than Gemini or ChatGPT, both of which build on prior context by default. Apple’s bet is that a significant segment of users would rather have less capability and more control. We will learn Monday whether that bet still holds in a market that has moved fast.

What we are watching at 10 a.m. Monday

The keynote starts at 10 a.m. PT (6 p.m. London, 7 p.m. Berlin). Beyond Siri 2.0, we will be watching for:

• New SiriKit domains: home, messaging, and media domains have been static for years; any new domain is a significant surface for third-party apps
• Liquid Glass in UIKit and SwiftUI: if this is the new system-wide design language, expect new component APIs and deprecated layout assumptions
• Cross-app intent chaining: whether Apple exposes a public API for composing intents across multiple apps in a single Siri session, or keeps that capability internal to its own apps
• Privacy architecture documentation: how Apple explains the chat history storage model will determine what developers are allowed to build on top of it

At Dracode, we build iOS apps where voice and AI integration are increasingly part of the brief. Our process is to read every framework diff before touching the AI integration layer, and that is what we will be doing Monday afternoon in real time.
