What’s New in watchOS

watchOS 5

This article summarizes the key developer-related features introduced in watchOS 5 and highlights the developer documentation that describes new features in more detail.

Siri Shortcuts

Siri can predict shortcuts to actions that a user may want to perform using your app and surface those shortcuts to the user on the Siri watch face. You determine which actions in your app are pertinent to the user and tell Siri about them by providing the actions as relevant shortcuts. watchOS 5 also includes support for any personalized voice phrases for shortcuts that users have set.

For more information about providing shortcuts donations in your apps, see Shortcuts in the developer documentation, or download the Accelerating App Interactions with Shortcuts sample code project.

Interactive Notifications

Dynamic notifications can now include interactive controls to make them more actionable. For more information, see Enabling Interactive Notifications and the WatchKit developer documentation

For information about syncing audio content, see the progress property of WCSessionFileTransfer and the WatchConnectivity developer documentation. For information about the new background mode for audio, see Playing Background Audio
