At its annual Worldwide Developers Conference (WWDC), Apple revealed new tools and features designed to empower developers to build smarter, more intuitive, and visually appealing apps across its platforms.
In a significant policy shift, Apple announced that developers will now have access to its foundational on-device AI model — the same large language model that powers Apple Intelligence. This move marks a departure from Apple’s historically walled-garden approach to developer tools and opens up new opportunities for app creators.
The foundational model, which runs entirely on-device, aligns with Apple’s longstanding commitment to privacy. However, the model’s three billion parameters reflect trade-offs in capabilities compared to the more powerful, cloud-based AI models offered by competitors.
“This is a major step — we’re giving all apps the ability to directly tap into Apple’s on-device large language model,” said Craig Federighi, Apple’s head of software, during the event, according to Reuters.
The new Foundation Models framework allows developers to incorporate Apple Intelligence features into their apps using just a few lines of Swift code. The framework offers privacy-focused AI inference at no cost, with built-in guided generation and tool-calling features.
Automattic, the company behind the Day One journaling app, is already leveraging this technology. “The Foundation Model framework has reshaped how we approach journaling,” said Paul Mayne, head of Day One. “We can now combine intelligence with privacy in ways that align with our users’ expectations.”
Apple’s latest update to Xcode (version 26) brings large language model integration directly into the development environment. Developers can access built-in AI features, including a version of ChatGPT, without needing a separate account. Alternatively, they can connect external API keys or run local models on Apple Silicon Macs.
The new Coding Tools feature supports developers by suggesting actions like creating previews, building playgrounds, and addressing code issues—all within Xcode itself.
Apple also expanded its Visual Intelligence capabilities, making them available to third-party apps via enhanced App Intents. Etsy, for example, is exploring how these features can improve product discovery. Rafe Colburn, Etsy’s CTO, noted: “Having the ability to meet shoppers where they are, right on their iPhones, with visual intelligence is a game-changer.”
This integration enables apps to provide search results within Apple’s Visual Intelligence experience, potentially boosting direct engagement through camera-based searches.
Following the event, Apple’s stock dipped 1.2% as some analysts questioned whether the announcements were significant enough to reposition Apple as a leader in AI. Thomas Monteiro, senior analyst at Investing.com, commented: “At a time when the market is questioning Apple’s AI leadership, the updates felt underwhelming.”
The company’s more restrained announcements contrast with the ambitious AI visions it shared last year. Bob O’Donnell, chief analyst at Technalysis Research, observed: “They went from pioneering with ideas like agents to focusing on delivering what they promised last year.”
While Apple’s on-device AI model aligns with its privacy-centric approach, it also limits what the AI can do compared to cloud-based models. Ben Bajarin, CEO of Creative Strategies, highlighted that Apple’s efforts remain more focused on backend improvements than on flashy front-end features that consumers might notice right away.
Developers can access Apple’s AI tools now through the Apple Developer Program, with a public beta expected in the coming weeks.
Apple’s choice to open its foundational AI model to developers, while maintaining a measured, privacy-first approach, signals its commitment to building sustainable AI infrastructure rather than simply making headlines with bold promises. As the AI competition heats up, Apple’s methodical strategy prioritizes user trust and steady growth over rapid, attention-grabbing innovation.
