Apple has been promising a radically new Siri for nearly two years. It just missed another deadline. But what’s coming — when it arrives — changes the rules of the game for anyone developing in the Apple ecosystem.
In January 2026, Apple signed a multi-year agreement with Google to integrate Gemini as the artificial intelligence engine behind a completely redesigned Siri. It’s not a minor detail — it’s the first time in Apple’s history that the company has outsourced its assistant’s core AI to a direct competitor.
The promise was ambitious. The reality, for now, is more complicated.
What Was Promised
The new Siri is not an incremental update. It’s a complete rewrite of the assistant, with capabilities that Apple has been demonstrating — without delivering — since WWDC 2024. The three core functions:
On-Screen Awareness — Siri will be able to “see” and interpret what’s on the user’s screen in real time, without relying on developers to manually tag accessibility elements. Ask about what you’re looking at and Siri understands it.
Personal Context — With access to messages, emails, and calendar, Siri will be able to maintain memory of previous interactions and reason about the user’s personal history. The classic example: “Where did I meet this person?” — answered with real user data.
Cross-App Control — Siri will be able to execute workflows that span multiple applications. “Find my flight information and request an Uber for when I land” — executed end-to-end, without human intervention.
Under the hood, all of this runs on what Apple internally calls Apple Foundation Models version 10, with approximately 1.2 trillion parameters — compared to the 150 billion of the previous model. The hybrid architecture processes what it can on the device, and scales to Apple’s private cloud only when necessary, maintaining the privacy focus that differentiates the ecosystem.
The Problem: Another Delay
The first beta of iOS 26.4 just came out — and the new Siri isn’t there. Apple was targeting this version as the debut, but internal testing revealed reliability issues: slow responses, queries that weren’t processed correctly, and cases where Siri fell back to ChatGPT handoff when it should have responded directly.
According to Bloomberg, Apple is now rolling out the new features across several future versions — possibly iOS 26.5 in May, and the bulk of the capabilities in iOS 27, which will be presented at WWDC in June with launch in September.
Apple confirmed to CNBC that the new Siri “remains on track for 2026.” Technically true. But this is the second time the company has missed a window that it itself promoted as a target.
To understand why Apple is being so careful: Google’s error with its image generation tool and multiple cases of hallucinations in competing assistants have made clear what happens when you launch AI at scale without sufficient validation. Apple guards its quality reputation with extreme caution, especially in products that touch personal data.
Why This Matters for iOS Developers
This is where the article shifts register. The delay of the new Siri is today’s news — but the implications for development in the Apple ecosystem are the more interesting story.
1. SiriKit and Intents APIs are going to change
With a Siri that can see the screen and execute cross-app workflows, the current SiriKit model — where the developer exposes specific intents that Siri can invoke — falls short. Apple will have to offer new APIs that allow third-party apps to participate in Cross-App Control flows. This opens a window of opportunity for developers who position themselves early.
2. The threat to “wrapper” apps
If Siri can operate directly in any system app without needing special integration, many applications that today offer “intelligent automation” as a central value proposition will face direct competition from the OS. Any app whose differentiator is “connecting” other apps or “acting on your behalf” needs to rethink its value proposition now.
3. Xcode is already anticipating it
Apple released Xcode 26.3 with direct integration of Claude (Anthropic) and Codex (OpenAI) within the editor. For iOS developers, this isn’t just a convenience — it’s a clear signal of direction: the development environment is becoming a multi-agent system where AI is a native part of the workflow, not an external tool.
4. On-Device AI as a new differentiator
Apple’s hybrid architecture — processing on the device when possible, private cloud only when necessary — creates a new privacy standard for AI-powered applications. Devs building for Apple in 2026 will have access to considerably more powerful on-device models than a year ago. That changes what’s possible offline and without compromising user data.
The Competitive Paradox
There’s something strategically odd about all this that’s worth naming: Apple chose Google — a direct rival in hardware and services — as its central AI provider for Siri. Meanwhile, Samsung has been using Gemini in Galaxy AI for months, and now that differentiator disappears.
For developers in the ecosystem, the message is clear: the era in which a single company controlled both the hardware and the AI model of its platform is coming to an end. The AI layer is separating from the OS, and unlikely alliances like this Apple-Google one will become more common, not less.
When Will We Actually See It?
The most likely scenario according to Bloomberg’s reporting: some minor Personal Context features in iOS 26.5 (May 2026), and the complete new Siri experience — including On-Screen Awareness and Cross-App Control — in iOS 27, announced at WWDC June 2026 and launched in September.
If you’re an iOS developer, that’s your window. WWDC June 2026 is going to bring the APIs you need to know to build apps that work well — or that survive — in the new Siri ecosystem.
Conclusion
Apple has been promising this for nearly two years. The delay is real, the frustration is understandable. But when it finally arrives, the new Siri represents the most profound change in how users will interact with their devices since the introduction of the touch screen.
For iOS devs, the question isn’t whether to prepare — it’s when to start. And the answer is: before WWDC.
