Microsoft's timing was the worst. I think they announced this a year after Swift was already announced, but before Swift was open sourced. So Microsoft wouldn't be able to deal with things like Obj-C/Swift interop which iOS developers were already jumping onto. And Microsoft's Windows 8 mobile initiative was pretty clearly a flop by this point.

Frankly, this Obj-C effort needed to be done way earlier, starting with AppKit, like back when Microsoft was panicking that OS X 10.4 Tiger was going to kick Longhorn's butt. If these tools had already been proven useful before the dawn of the iPhone, Microsoft might have had a chance of riding the iOS wave.
