How iPhone Apps Can Use AI Agents to Automate Multi-Step User Tasks

For example:

“Send my latest expense report to Sarah.”

The system can identify the relevant document, understand the intended recipient, and invoke the appropriate app action.

Apple's App Schemas are designed to make app entities and actions understandable to Siri. Developers describe the actions an app supports, their parameters, and how those actions should be executed.

This changes the role of the app interface.

Instead of forcing users to navigate:

Dashboard → Reports → Expenses → Latest Report → Share → Contact → Send

the app can expose the underlying capability so the system can execute the workflow through natural language.

The interface still matters, but the interface becomes one way of accessing functionality rather than the only way.

5. Replace Long UI Flows With Goal-Based Interaction

AI-agent-driven interfaces are increasingly moving toward a model where users describe outcomes instead of navigating through individual controls.

Consider a project-management app.
