iOS 16.1 is currently available in beta testing and includes support for the Live Activities API, which allows developers to add real-time notifications to the Lock Screen and Dynamic Island. As iOS 16.1 nears a public release sometime this fall, Apple has now published its full Human Interface Guidelines that outline best practices for developers implementing Live Activities in their applications.
Live Activities were announced at WWDC as a way for developers to add real-time, up-to-date information to the iPhone Lock Screen. Then, the full scope of the feature was announced when Apple unveiled the Dynamic Island on the iPhone 14 Pro and iPhone 14 Pro Max. In addition to the Lock Screen, developers will be able to show Live Activities directly in the Dynamic Island as well.
