You make good points, and I think I am overreacting! Frankly, it's misleading/silly for me to complain about Swift additions since I don't have the opportunity to write much of it, and primarily only read/consume it with Obj-C code. (I have no choice in this matter.) Basically the language already has a high cognitive load for me, so of course any additions feel burdonsome. Also, I'm unfamiliar with using KeyPaths like that, so I'm clearly way off on my reaction to them. The general goals of Swift make me want to learn it better and use it, honestly.
