Objective-C Enters Top Ten In Language Popularity

bonch writes "Objective-C has entered the top 10 of the Tiobe Programming Community Index. Last year, it was at #39. The huge jump is attributed to its use in iPhone and iPad development. C, of which Objective-C is a strict superset, has reclaimed the #1 spot from Java, which slides to #2. Tiobe also explains how it determines its rankings."

What language for business logic?

[tepples]

There is one popular computing platform that requires all programs to be written in Objective-C. There is another popular computing platform that requires all programs to be written in one of the many languages that compile to verifiably type-safe CLR bytecode, but Objective-C is not one of those languages. So if I want to develop an application for both of these platforms, in what language should I express the business logic of the application so that it can be automatically translated into Objective-C and into a CLR-friendly language?

No you can't. Well, you can (in theory, except that back end is painfully buggy), but you also need to use Clang and LLVM to compile an Objective-C runtime for the CLR. You can't compile the Apple one, because it contains per-platform assembly for the message sending, but you can (in theory) compile the GNU one, which is portable. You then end up running one object model on top of another object model, with two conflicting memory models. If anything nontrivial works, you deserve a prize.

(I am the maintainer of the GNUstep Objective-C 2 runtime and the author of the GNU runtime support and a few other bits of Objective-C in Clang).
