The dream of COM is alive in Cupertino!

  Not really? The example for Messages seems very specific; closer to an API for Messages.app than a generic process interop framework.

  OpenDoc would be more relevant to Apple: https://en.wikipedia.org/wiki/OpenDoc https://en.wikipedia.org/wiki/OpenDoc

  They at least decided to go with a sane language instead of C++ Also is it really COM like? it doesn't look like it EDIT: https://www.chimehq.com/blog/extensionkit-intro https://www.chimehq.com/blog/extensionkit-intro https://news.ycombinator.com/item?id=33410067 https://news.ycombinator.com/item?id=33410067

    COM is language agnostic.

      Language agnostic in that COM lets you use the C++ object model in any language you want.

        Not really except in that QueryInterface returns a pointer to a struct of function pointers. It doesn't place a requirement on the layout of the object (for example you can use a fat pointer for a COM object, which is incompatible with the C++ object model)

        On top of the sibling comment, as of WinRT, COM has been extended with a new ABI, based on additional base interface (IInspectable), replacing TLB libraries with .NET metadata, and support for generics (.NET style). So it isn't the C++ object model per se.

        As someone who programmed COM back in the day for C++ applications, I can tell you definitively that you got no benefits over other languages outside of brittle macros and non-standardized Visual C++ compiler magics. Especially once you crossed over into Office/VB land, and everything was just IDispatch, Variants, BSTRs and SafeArrays.

  COM has been alive for quite some time, not only does Taligent and Copland ideas precede it (the IDL is lously based on DCE/RPC), similar ideas are used in the IOKit, DriverKit and XPC.
