Is there a way to check if the user has the Watch App Extension installed in his/her Apple Watch?
I need to add Firebase Events to an Apple Watch App to see how frequent is the Apple Watch App used but as far as I know Firebase is not supported in the Apple Watch.
You can use the isWatchAppInstalled instance property of your WCSession object to determine if the Watch App is installed or not. It returns a Bool value you can use in your code.
More information on this can be found in the developer docs: https://developer.apple.com/documentation/watchconnectivity/wcsession/1615623-iswatchappinstalled
