The question is, where does ObjC end and where does Swift start? When Apple announced an Objective-C without the C, I assumed they'd keep the Smalltalk object system and message passing. It still boggles my mind that they took a hard turn into the world of value semantics and extremely static types, with all the ABI problems that we know from C++, plus all the interop hacks to bridge both worlds. The syntax almost seems like a superficial detail compared to the new object model. On the other hand, the Smalltalk model would not have worked for SwiftUI. It really feels like Apple has bet the farm on the next generation of libraries/frameworks.
