I am using Visual Studio 2015, and have updated my mac to the latest Xamarin release as well.
I create a new project, "Blank App (Xamarin.Forms Shared)"
After project creation, I open "Manage NuGet Packages for Solution..."
I upgrade to the latest stable Xamarin.Forms, since the project created it with version 1.3.3.6323. NuGet tells me it is updating to 1.5.0.6446, and also updating Xamarin.Android.Support to v22.2.1 I have to restart Visual Studio after this process by request of NuGet, so I do that.
When this finishes, I try building without any code changes. I set each respective project to the VS "startup project" and build.
WinPhone:
Succeeds with Debug - Any CPU as the configuration.
Android:
Succeeds with Debug - Any CPU as the configuration.
iOS:
Succeeds with Debug - iPhoneSimulator as the configuration.
iOS:
Fails with Debug - iPhone as the configuration.
"Failed to create the a fat library. Please review the build log." (I've tried finding the build log, but can't...where is it?)
Now, I only have one copy of Visual Studio 2015 running. If I close Visual Studio, reopen it, try the project again with rebuild, I get the same results.
The iOS problem seems to happen on Visual Studio 2013 as well; the WinPhone and Android build fine, following the same steps, putting files in the same directory, etc.
What do I do here? What is "a fat library"? I've tried changing the project settings to no avail (for example, Deployment Target: 7.0, Supported architectures: ARMv7 + ARMv7s + ARM64).
Please help!
