Apple Opens Siri AI App Integration to Developers in a New Preview
Apple opened its Siri AI Developer Preview to all developers on November 3rd, giving app makers a way to connect custom content and actions to the assistant. The preview arrives with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas on supported Apple Intelligence devices.
The change matters for the everyday tasks people perform across apps: finding information, arranging a service or moving selected content into another app. Apple is offering developers tools to build those connections, but the announcement does not mean every installed app can now perform those tasks through Siri.
Apps must explicitly expose their actions
Apple’s developer documentation says Siri can access only the custom content and actions an app explicitly makes available through App Intents. Developers can also define skills that guide the assistant through more complex requests involving several actions.
The documentation describes different behavior depending on context. An app may not need to be named when it is in the foreground or has an active Live Activity. For an app running in the background, a person can identify it in the request. These are capabilities for developers to integrate and test, not independent performance results.
Apple also provides an integration advisor in Xcode and a framework for testing Siri requests. Developers can use those tools to evaluate whether their app’s actions behave as intended and identify changes as the integration evolves.
Public availability is still ahead
Testing is currently limited to development builds and internal TestFlight testers. Apple says the preview’s custom integration functionality is unavailable to external TestFlight testers and people downloading an app from the App Store.
The company says customer delivery is expected in a few months, with App Store submissions opening in the spring. Features and interfaces may change during the preview. Apple also says more detail on terms and usage policies will follow, so developers do not yet have a complete commercial picture.
For consumers, the useful distinction is between a new development opportunity and a finished feature in an everyday app. The preview gives app makers time to build and evaluate experiences before wider availability. PowerPage’s Technology coverage will follow material changes to that availability and the requirements attached to it.
Watch: WWDC26 Siri preview
Apple’s official WWDC26 preview introduces Siri AI and related Apple Intelligence features. This earlier preview provides background; it is not a video announcement of the November 3rd developer-preview release.
