Siri for developers

Siri open on iOS, iPadOS, watchOS, and HomePod.

What’s new

In iOS 18, iPadOS 18, and macOS Sequoia, Siri is more natural, more personal, and more deeply integrated into the system. Apple Intelligence provides Siri with enhanced action capabilities, and developers can take advantage of predefined and pretrained App Intents across a range of domains to not only give Siri the ability to take actions in your app, but to make your app’s actions more discoverable in places like Spotlight, the Shortcuts app, Control Center, and more. SiriKit adopters will benefit from Siri’s enhanced conversational capabilities with no additional work. And with App Entities, Siri can understand content from your app and provide users with information from your app from anywhere in the system.

Seamless messaging and calls

Siri selects the app best suited to message or call a contact, even without the user saying the app’s name. And Siri supports audio messages, the ability to edit or unsend messages, rich attachment reading, and fast contact resolution through system intelligence.

App Shortcuts

In iOS 17 or later, Siri can recognize variations of trigger phrases for your App Shortcuts. For example, an App Shortcut with the phrase “Scan files” can also be triggered by similar phrases, like “Scan page” or “Help me scan this document.”

Integrate your music streaming service

SiriKit Media Intents on HomePod let streaming music services integrate directly with HomePod to deliver a seamless playback experience. People can simply ask Siri to access music and playlists from your service and play them on one or multiple HomePod speakers throughout the home.

Siri support for AirPlay on HomePod

In iOS 17 or later and HomePod software version 17, people can use Siri to start an AirPlay session from HomePod and play media (like music, audiobooks, podcasts, radio, and meditations) using apps installed on their iPhone or iPad. Any app that adopts SiriKit Media Intents and AirPlay works with HomePod.

Apps adopt SiriKit by building an extension that communicates with Siri, even when your app isn’t running. This extension registers with specific domains and intents that it can handle. Siri handles all of the interaction, including the voice and natural language recognition, and works with your extension to get information and handle requests.
