An easy to follow guide that will lead you through the process of binding Swift .framework files for use in a Xamarin project.
When building a library in Xcode it has an option to include the swift libraries. Don’t! They will be included in your final app as NAME.app/Frameworks/LIBRARY.framework/Frameworks/libswift*.dylib but they must be included as NAME.app/Frameworks/libswift*.dylib
You can find this information elsewhere, but it’s worth mention: Don’t include Bitcode in the library. As of right now Xamarin don’t include Bitcode for iOS and Apple requires all libraries to support the same architectures.
