I'm just trying out the newly published platform declarations d.ts files. But using tns-core-modules and tns-platform-declarations packages I still face problems compiling correctly code that uses interop for iOS for example. From what I see that is defined in the declarations.ios.d.ts file which is missing from both packages. I guess that there will be problems when you use something specific from the android specific file as well. Thus I think those files should be published as part of either tns-core-modules or tns-platform-declarations packages
