Apple is opening Siri AI to third-party developers, but the expanded integrations are currently limited to developer testing.
On November 3, 2026, Apple introduced a Developer Preview allowing apps to expose custom actions and content through App Intents. Available in the iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas, the preview expands Siri's ability to understand requests and perform tasks within supported applications.
Enterprise software teams can begin exploring new customer service and productivity workflows. Commercial deployment remains uncertain, however, with final usage policies and distribution dates still outstanding.
What developers can build with Siri AI
Under Apple's expanded developer preview, applications can expose custom actions that Siri AI interprets using natural language, personal context, and onscreen awareness.
App Intents already allowed developers to expose actions through Siri, Shortcuts, and Spotlight. The November preview expands Siri AI's ability to use custom actions beyond predefined schemas, making more application workflows accessible through natural-language requests.
Apple also introduced skills, which combine multiple actions into a single Siri AI experience. Expanded Spotlight indexing allows Siri to retrieve app entities that do not match existing schemas.
In one example from Apple's developer documentation, someone tracking a ride through a Live Activity could ask Siri to change the pickup location without naming the app again. This illustrates how contextual information could simplify interactions, rather than confirming that a particular ride-hailing service already supports the feature.
Developers must still define the actions and content their apps expose. The update does not give Siri unrestricted access to installed applications.
Apple's rollout has already faced availability questions, including an August report about possible waitlist restrictions. The November developer preview introduces a separate limitation: Apple has opened the expanded Siri AI capabilities for testing, with App Store submissions for the new integrations planned for spring.
Developers can experiment on compatible Apple Intelligence devices. Apple expects the first customer integrations in a few months, although neither that milestone nor the App Store submission window has an exact date. Final usage policies are pending, and integration behavior may change during testing.
Regional availability adds another limitation. Under Apple's June 8 EU statement, developers located in the European Union cannot test the new Siri AI features on iOS, iPadOS, or watchOS. Supported Macs and Apple Vision Pro devices are not subject to the same restriction.
Apple attributes the mobile exclusion to disagreements over the Digital Markets Act and has announced no resolution date.
What eWeek Found: Expanded Siri actions outpace deployment readiness
Apple has expanded what developers can expose to Siri AI without establishing when those integrations will be ready for commercial distribution.
Earlier integrations relied on defined actions and schemas, while the November preview lets Siri AI interpret a wider range of custom workflows. However, Apple's technical materials distinguish testing individual app functions from evaluating how Siri interprets and executes conversational requests.
Apple's App Intents Testing framework provides tools for testing app intents. From an enterprise testing perspective, validating an individual action does not establish that Siri AI will consistently interpret ambiguous requests or select the intended operation. Those behaviors require additional evaluation.
An October 2026 Argo-Bench assessment of enterprise AI agents found that the top-performing model scored at least 95 out of 100 on just 34.8% of 210 business tasks. Those results do not measure Siri, but illustrate why completing an action and achieving the intended business outcome require separate evaluation.
Enterprise developers must also consider authorization, sensitive actions, and regional compatibility. The challenge of discovering AI agents and controlling data exposure highlights the need for visibility and oversight when software acts on users' behalf.
Enterprise teams can begin building and testing Siri integrations, but committing to a customer rollout remains premature until Apple finalizes its API behavior, usage policies, and distribution rules.
