As far as I know, I'm not using Nibs in my app, so I'm not sure why this error exists. I'm using Views and Xaml to create my Pages. Here is the error.
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Error: System.IO.FileNotFoundException: /Users/userName/Development/FaceOffers-9/Xamarin_FaceOffers/FaceOffers/FaceOffers.iOS/obj/iPhone/Debug/build-iphone8.1-9.2.1/ibtool/LaunchScreen.storyboardc/UIViewController-X5k-f2-b5h~iphone.nib/objects-8.0+.nib does not exist
