The packages for Swift 4 and 3.2 aren't uploaded to Nuget as an update to the old ones, but as entire new set of packages - I guess the initial name for the packages was not very good.

The new libraries (8 in total) added in Xcode 9 are:

• libswiftAccelerate
• libswiftARKit
• libswiftCoreFoundation
• libswiftMediaPlayer
• libswiftMetal
• libswiftMetalKit
• libswiftModelIO
• libswiftVision

If you are using Swift 4 or 3.2 you should be using this packages:

Xamarin doesn't yet provide support for binding Swift libraries. This project is a try to provide all Swift3 runtime/libraries in a organized way.

Each library dependecy is provided through a NuGet package, all of them will depend on Xamarin.Swift3 package which only include a MSBuild target file for moving the denpendencies when using Simulator and Device.

Do not include them all as dependency in your project as it will increase the final App size. Use just what you need.
