You say 'beloved Objective-C'. Sorry if this is really off topic, but is objc_msgsend (the whole late-binding thing) or anything else about Objective-C particularly appealing? Maybe the decent unoptimized speeds or the fact that you can use plain C whenever?

I love C because I do a lot of low-level programming and I feel closer to the machine with C. For higher level UI stuff I like the Smalltalk extensions to C and Obj-C's dynamic nature and the fact that I can use C (and C++ directly).

Also I have been programming the Mac for a long time and I have a lot of mental investment in Objective-C.

OTOH, I do like the functional, strongly-type features of Swift, but like any higher level language I feel more removed from the machine. That's the price for abstraction.
