Greetings fellow WatchOS app developers, On the iOS simulator running 12.5 beta, the method updateApplicationContext() claims that it succeeded, no exception is thrown and yet the WatchOS app, running on a WatchOS 7.4 simulator never gets its language session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) method invoked. Same issue in the other direction: The WatchOs app claims success on updating the iPhone app's application context. Yet nothing arrives. This works fine on real devices running iOS 14.5 beta and WatchOS 7.4 beta. Are there any workarounds? Due to Covid-19, I'm working remotely and can't debug on a real device, and need to be able to debug a critical WatchOS 7.4 specific issue. Thanks in advance!

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

In order to determine what is wrong with my simulators' behavior, Apple is asking me to run sysdiagnose on all devices involved. However, aside from my mac mini, all other devices involved this issue are simulators. Can one run sysdiagnose on a simulator for iOS and WatchOS? And if so how? Thanks in advance
