Apple opens Siri AI app integrations to all developers in limited preview

Apple is giving every developer a way to put their app’s actions within reach of Siri AI, including tasks that combine several steps. The Developer Preview opened November 3, 2026, across four operating-system betas. It is an opening for app builders, not a customer release: Apple says these integrations will reach users in a few months.

Giving Siri actions it can use

The connection runs through App Intents, Apple’s framework for exposing an app’s content and actions to the assistant. Developers define the actions their software supports; users ask for them in ordinary language. Apple gives checking a delivery, booking a reservation and placing an order as examples of requests an integrated app could handle.

Context can reduce how much a person needs to spell out. In his account of Apple’s documentation, MadRobot’s Vikram Singh describes requests that do not need an app’s name when it is onscreen, has a Live Activity running or appeared earlier in the conversation. A ride-share customer, for example, could ask to change their pickup address.

The same account describes Siri passing content between apps, such as finding saved sneakers in a shopping app and sending them through a messaging app. Siri can also act on a named app in the background. Results appear in cards that use the app’s own design.

Apple is also widening what Siri can retrieve. The assistant can surface any entity in the Spotlight semantic index—the search index used to find content by meaning—rather than only entries that match an existing predefined structure. That change concerns finding app content, alongside the preview’s ability to invoke app actions.

Skill files guide a task, not a script

For requests that need several actions, Apple is introducing skills. Singh reports that each skill is a Markdown text file named SKILL.md. A name and one-line description help Siri decide whether it fits a request. Plain-language instructions explain which actions belong together, which to prefer, what to avoid and any app-specific knowledge.

A shopping example in Apple’s guide covers searching for products, filling a basket, selecting payment and delivery, and confirming the order. But a skill is not a program that forces those steps to run in sequence. Apple’s documentation makes that distinction explicit, as quoted by Singh:

You can’t use app skills to enforce deterministic behavior

Apple is pairing the integration work with tools for checking how Siri responds. Singh identifies two additions that help developers improve their app’s exposed actions and test requests as their code changes:

• Siri Integration Advisor in Xcode suggests fixes to an app’s intents.
• The SiriEvaluations framework lets developers script requests and check how Siri handles them.

Open to developers, restricted to testing

The preview arrives in the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. During this phase, integrations work only in builds developers run themselves or distribute to internal TestFlight testers, Singh reports. External testers and App Store versions are excluded. Apple says App Store submissions will open in spring.

Apple has begun rolling out related capabilities in its own apps, including Calendar, Files, Mail, Maps and Photos. Its examples include finding a coffee shop visited last week and archiving files unopened for more than a year. Those actions give developers reference points while they build their own integrations.

Access still requires an Apple Intelligence-enabled device set to a supported language. Siri AI remains unavailable in the EU on iOS, iPadOS and watchOS. And the rules for these new integrations are not final: Apple says it will provide more details about terms and usage policies as developers explore the preview.
