Apple gives me this error when uploading an iOS App with a bundled watchOS app:
ITMS-90484: Invalid WatchKit Support - The WatchKitSupport2 folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.
VS bug #1214349

Please provide a complete build log, the version information, as well as the .ipa you tried to upload.

@rolfbjarne what service is preferred for uploading the IPA?

@rolfbjarne what service is preferred for uploading the IPA?
Whatever is easiest for you as long as we can download it. Dropbox is pretty common, but there are plenty of other services.
@rolfbjarne https://www.dropbox.com/s/fuz42lb0rqubzkv/VrhealthLife.iOS.ipa?dl=0 that work?
@jWalker92 Yes, that works, I'll have a look next week since it's getting late here.
This might be something that happens when building from Windows.
@jWalker92 can you try building using Visual Studio for Mac, and see if the resulting .ipa contains a WatchKitSupport2/WK file? The .ipa is just a zip file, so you can view the contents using any tool that can look into zip files.

Can confirm, VS-Mac creates the ipa correctly, whereas VS-Windows does not. So workaround is publishing on the Mac.
@jWalker92 ok, thanks for confirming that. I've assigned this to the team responsible for Xamarin.iOS on VS/Windows.
Any workaround for this using Xamarin on Windows
Hi this was logged a month ago, we cannot update our watch app. Is there an ETA?
