WWDC26: Updates on AI, developer tools, and the state of iOS measurement

Apple's June 8, 2026 Worldwide Developers Conference (WWDC26) included no notable measurement updates, and was dominated by AI announcements and features. 

The opening keynote focused on Siri (the new Siri AI), integrated into a rebuilt and expanded, “next generation” Apple Intelligence built on Foundation models co-developed with Google and their Gemini family of models. As always, the Platforms State of the Union then shifted the conversation from the user experiences side to the technologies developers will use to create them.

For app teams, this year's announcements were less about attribution and measurement than they were about AI infrastructure and feature development tools. The new Core AI framework, updates to Xcode 27, and the App Intents framework were among the announcements. 

Here's a look at the announcements most relevant to mobile businesses.

The Foundation models framework is a native Swift API that gives developers direct access to the same on-device model that powers Apple Intelligence, with new support for image input, server models, and third-party cloud model providers. The framework will also integrate with models such as Gemini and Claude, giving developers more choice in how they build AI-powered features.

Core AI was also introduced, a new framework designed to help developers run and optimize specific AI models directly on Apple devices. Rather than relying solely on Foundation models, developers can bring their own generative models to the platform and take advantage of both on-device processing and Private Cloud Compute infrastructure.

App Intents also received updates. By contributing app content to the Spotlight semantic index and adopting App Intents schemas, developers can make content and actions available to Siri AI and Apple Intelligence. This allows users to find information and complete tasks using natural language, rather than navigating directly through an app.

Xcode 27 received a significant update, with a particular emphasis on agentic coding. Developers can now use agents to perform tasks such as running tests, interacting with simulators, localizing apps, debugging issues, and exploring code in Playground.

Xcode now includes integrations with Anthropic, OpenAI, Google, and any compatible agent using the Agent Client Protocol (ACP), allowing developers to bring existing AI workflows directly into the development environment.

Beyond AI, Xcode 27 introduces a redesigned daily experience, including faster project loading, iCloud-synced settings, a new Device Hub that combines simulators and physical devices, and improvements to Xcode Cloud.

Unlike WWDC25, Apple did not announce significant updates to AdAttributionKit or SKAdNetwork (SKAN), attribution windows, postbacks, crowd anonymity tiers, or re-engagement measurement capabilities.

For marketers and measurement teams, this means Apple’s attribution framework remains largely unchanged heading into the iOS 27 cycle. While attribution wasn’t a major focus of this year’s event, the lack of changes provides continuity for teams continuing to build and optimize their existing AdAttributionKit strategies.

One more notable update is the addition of cross-developer subscription bundles and group purchase capabilities within the App Store, part of an initiative to create new ways to market apps and games with “enhanced discovery and engagement”.
