SiriKit is designed to allow iOS and watchOS apps to work with Siri, so users can complete tasks with Siri voice commands. SiriKit is available for a wide range of apps on those two platforms, but its availability is slightly more limited when it comes to HomePod.
Third-party apps that use SiriKit Messaging, Lists, and Notes are compatible with the HomePod. Siri will recognize voice requests given to the HomePod, with those requests carried out on a linked iOS device. So, for example, users can ask HomePod to send a message to a friend, add an item to a list, or create a new note. Sample HomePod requests:
- Send a text to Eric using WhatsApp
- In WeChat, tell Eric I'll be late
- Add chocolate and bananas to my list in Things
- Create a note that says "hello" in Evernote
Developers can test the voice-only experience of their apps using Siri through headphones connected to an iOS device with the iOS 11.2 beta.
Apple plans to release the HomePod this December, but a specific launch date for the speaker has not yet been provided. When it becomes available, the HomePod will cost $349.
