I tried to customize the storyboard of my Xamarin.Forms App actually I only added a png and changed some to the properties in since then I cannot built the project anymore due to this error
error : 2016-06-20 18:59:16.005 ibtoold[4929:77525] Exception raised while unarchiving document objects - Unexpected element "accessibilityConfiguration" for key "traits" while decoding "accessibility".
I'm using VS with a Mac Mini as Building host.
On SO is another dev with the same problem http://stackoverflow.com/questions/37679820/xamarin-ios-building-to-a-remote-mac-build-host
I attach the storybook
P.S.: @JWhite as you said :-)
