I am having trouble getting the new mirroring session API to send data to the companion device.
when starting a workout on my watch I call startMirroringToCompanionDevice and then go onto my iOS workout manager to handle it via the workoutSessionMirroringStartHandler, I set the delegate here and can confirm that it is indeed not nil within that function but when I go to send some data across I get an error saying the remote session delegate was never set up.
I noticed this same behaviour in the WWDC demo and have been unable to find a solution that will allow me to send data across the mirrored session even though I am able to control the workout session state(pause, resume, end) on both Phone and Watch.
Has anyone else encountered this issue? Anyone have a solution?
Sending data between a watch app and its companion iOS app via a mirrored workout session is demonstrated in the Building a multi device workout app sample. You might want to give it a try, if not yet. If the sample has the same issue, you can file a feedback report with detailed steps to reproduce the issue, and post your feedback report ID here.
