your binary is not optimized for iphone 5

I have an error when attempting to upload my ipa using the application loader. I am using visual studio 2017 on the latest xamarin build 4.5
I am using a LaunchScreen.storyboard. I also have the the iPhone 5 images in the asset catalog.
Anyone else having problems or could offer a solution?
