Earlier this week, Apple released watchOS 3.2 to developers. This update brings a few noticeable changes, mainly the Theatre Mode and access to SiriKit so third parties can provide services through Siri on watchOS.
According to the official page about the changes coming with watchOS 3.2, "Theater Mode lets users quickly mute the sound on their Apple Watch and avoid waking the screen on wrist raise." While using this mode, users can still receive notifications. Viewing them requires tapping the screen or pressing the Digital Crown.
The set of SiriKit services supports covers the following domains: messaging, workouts, payments, ride booking, calling, and searching photos. To provide services via Siri, developers have to create app extensions with the help of the Intents and Intents UI frameworks.
At last, watchOS 3.2 also provides a new method in the WKAudioFilePlayerItem class that allows programmers to specify an offset in an audio file.
