Demo project that fails when trying to run test

We have been trying to get iOS UITests working for our Forms app, but we always get the following error:

    SetUp : System.Exception : The app bundle in [path].app does not seem to be properly linked with Calabash. Please verify that it includes the Calabash component.

I even tried setting up a new project from scratch, using the documentation provided here:
https://developer.xamarin.com/guides/testcloud/uitest/
But even in a brand new project with a brand new app, I get the same error.

The zipped project is attached.

Note:
- Xamarin Test Cloud Agent component is referenced in the iOS project
- Application.Main is calling Calabash.Start()
- UITest project references and correctly finds the .app output

All the documentation indicates that this should be sufficient for getting testing to work.

@Calvin,

Please try putting Xamarin.Calabash.Start() into the AppDelegate.FinishedLaunching method. Just in case you haven't seen it yet, here's our guide to adding support in Forms apps: https://developer.xamarin.com/guides/cross-platform/xamarin-forms/uitest-and-test-cloud/#Adding_Support_in_Xamarin.Forms_Apps. 

Please let me know if you continue having any difficulties. Thanks!

I moved Xamarin.Calabash.Start() from Application.Main into AppDelegate.FinishedLaunching, cleaned, and rebuilt all projects.  Same result.

For record-keeping, G. Wilson is working on this via http://forums.xamarin.com/discussion/comment/164388/#Comment_164388.
Comment 4 Rolf Bjarne Kvinge [MSFT] 2015-12-03 15:16:26 UTC
This happens because when a project is built for both 32-bit and 64-bit simulator, we don't build a fully functional app that can be installed as-is, instead we build something that at launch time (when we know if we'll be launching in a 32-bit or 64-bit simulator) we tweak to become a fully functional app (for the corresponding simulator).

The workaround is to build for a single architecture in your app (you can select it in the iOS Build options for the project).
Comment 5 Rolf Bjarne Kvinge [MSFT] 2015-12-03 15:28:16 UTC
I've filed an issue with the corresponding team to get a better error message in the future (it'll tell you to select a single architecture in the project).
Comment 6 calvin.fisher 2015-12-23 17:48:09 UTC
Thanks Rolf, I can confirm that the selecting-a-single-architecture workaround resolved it for us.  A better error message would probably suffice to lead people on the right path in the future.
Comment 7 Rolf Bjarne Kvinge [MSFT] 2015-12-23 18:24:46 UTC
@Calvin, the UITest team has already fixed the issue I reported, and in the future you'll get an error message asking you to select a single architecture.
