Hello,
This version of the SDK now has support for iOS App Extensions, including Apple WatchKit Extensions. You can now include the SDK inside of a WatchKit App and send usage data to Mixpanel as you would with an iOS app. There are some important differences that I'll highlight below.
-- We've removed functionality that's not applicable to app extensions including Mixpanel Surveys and In-App Notifications. This can be done by adding the MIXPANEL_APP_EXTENSION macro to your build settings.
-- All track calls are immediately sent to Mixpanel instead of being buffered and flushed periodically.
If you have any questions or experience any difficulties, please email sup...@mixpanel.com to speak to someone smart, quickly.
