Only time will tell: Swift isn’t even a year old!

Obj-C/C++ is a mature language, with cross-platform support already. (If a GCC exists for the specified target, then you can use generic Obj-C)

For now, Swift is a proprietary language, and its features could change or break at any time.

I don’t expect Microsoft to support Swift for some time. If they decide to do so, they might even have to reverse-engineer the Swift runtime, Chinese-wall style.

I will even go so far as to say that Apple is the one trying to lock-in developers: Swift apps require iPhone OS 7+, and I don’t see Apple making Swift cross-platform any time soon.

FWIW, the fact that MS is even making such an effort, is rather unprecedented.

Also, I think Apple created Swift in response to the realisation that Objective-C was no longer under their control. A development system that they can keep to themselves.

You know, to give Apple products that air of exclusivity that they crave. All part of the Apple ecosystem MO.
