I did get to gloat to a very Apple obsessed coworker today.
He was under the opinion that Swift was going to take over the world (including server space) because Apple told him so.
I did predict this dropping of Swift by IBM because after the initial hype, it turns out that there is so much legacy code written in C/C++ that is too much of a pain to create binding layers against. Most, if not *all* of IBMs products are for maintaining legacy business systems and so Swift just brought in an endless and pointless layer of binding requirements.
For my next prediction, Apple will drop Swift and re-focus on Objective-C (similar to how Microsoft is falling back on C++/winrt and is diverting away from C#).
Again, this prediction is due to the binding issue with Swift. More effort than its worth.
