Hi,
Xcode 12.5's iPhone simulator silently fails in sending its app context via updateApplicationContext() to the Watch simulator. No exception is thrown, so it appears as if everything is ok - but not really because the WatchOS simulator never gets the app context

This works fine on real devices as well as earlier versions of Xcode.

Doing a updateApplicationContext() from the WatchOS simulator to the paired iPhone simulator does work.

I filed a bug report for this issue, because this behavior has been in Xcode 12.5 since the beta version:
FB9095737 (Xcode 12.5 WatchOS Simulator never receives application context from iPhone counterpart)

Before anyone says "why not debug on a real device instead?", please be aware that due to the pandemic, while I do test on real devices, I can only debug on a simulator.

Thanks

I've installed the latest Mac OS (12.3.1) and Xcode 13 and although I can send messages and context updates to/from real devices (a series 7 watch to an iphone 13 mini) I can only send them in one direction i.e. watch to phone, on the simulator. The Series 5 simulator works for messages, but not context updates. The Series 6 doesn't communicate with the companion app in either direction!
