iPhone App References editor

1. I have existing iPhone app solution.
2. Right click on solution - Add New Project - watchOS -  WatchKitApp (template for watchOS 2.0 or later)
3. Choose watch simulator - Run app

Actual result:

error MT0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com
System.IO.FileNotFoundException: Could not find required file '/Users/admin/<SolutionFolder>/<iPhoneAppProjectFolder>/bin/iPhoneSimulator/Debug Staging/<iPhoneAppName>.app/Watch/<WatchAppName>.app/Info.plist'.

Expected result:
Watch App runs on watch simulator

Additional info:
1. All bundle identifiers were set properly according to this guide https://developer.xamarin.com/guides/ios/watch/installation/#Set_Project_References_and_Identifiers
2. Linker behavior option (for iPhone and watch apps): Link FrameWork SDKs only
3. iPhone App project references WatchApp project; WatchApp project references WatchExtension project. According to this guide https://developer.xamarin.com/guides/ios/watch/installation/#Set_Project_References_and_Identifiers 'iPhone app references Watch Kit Extension and Watch Kit Extension references Watch App'. Is this a bug? Furthermore XS doesn't allow to change references (as it done in guide example) - please see screenshot attached

@Vincent please check this
Comment 2 Vincent Dondain [MSFT] 2016-09-01 11:44:30 UTC
Hi, so watchOS projects are working fine with latest versions of XS and XI. I can deploy on both the watchOS 2 and watchOS 3 simulators and device.

I believe there is a possibility you're hitting the issue covered in https://bugzilla.xamarin.com/show_bug.cgi?id=43610 (in that case it's a reference to Microsoft.Bcl.Build.targets in the main app that break app extensions and watch apps and removing the import in your main project's csproj should fix everything).

You could be hitting something else but in order to investigate precisely we'd need a full verbose build log (Xamarin Studio > Preferences > Projects > Build > Log verbosity > Diagnostic) and also if possible a test case so we can check your project options and easily reproduce the issue here.

I'm putting the bug on NEEDINFO to let you confirm if you're hitting the Microsoft.Bcl.Build.targets issue or provide us with the additional information we need to help.
Comment 3 Victor 2016-09-01 14:17:25 UTC
Thanks a lot @Vincent for explanation. I'll remove Bcl targets in the main app and try to build/launch watch app tomorrow and write about results here
Comment 4 Victor 2016-09-06 09:13:38 UTC
Hi, @Vincent. I've removed Bcl.Build targets and moved other iOS targets to the bottom of iPhoneApp.csproj file. So now I can run/debug watchApp. Thank you for advice.
But I'm faced with another issue - any changes (e.g. in storyboard in Xcode IB) in WatchApp (not Extension) don't appear if WatchApp marked as Start Up project. They appear only if I rebuild and launch main iPhone app. Should I file new bug or leave it here.
Comment 5 Vincent Dondain [MSFT] 2016-09-06 09:19:48 UTC
@Victor, yes please file a new bug as this one is indeed solved.

FYI, the new bug should be for the iOS product and the MSBuild component, we'll have a look as soon as possible.

I'm closing this bug as ANSWERED.
