Having worked on the old, the migrating, and the new, I appreciate Swift more than Objective-C mostly due to IDE support.

If they had put the effort into Objective-C++ that they put into Swift, I struggle to imagine it in a worse place than Swift is in these days.

Any language that is copy-paste compatible with C is a lost cause in regards to security.

From language features and community culture point of view.

I think that is a bit of an overstatement given the amount of legacy code and bindings generation capabilities. I do think it had to swing towards memory safe and C++ still didn’t have a plan for smart pointers much less move semantics when Swift dev started.

Who knows what present day Objective-C++ could have been if it had been the workhorse language of choice. Maybe this profiles thing Bjarne is pushing could have been in the roadmap. We will never know.

Not at all, besides Objective-C would have been dead by now, had it not been for NeXT reverse acquisition of Apple.

Additionally Objective-C++ never was seen anything beyond interop with existing C++ code, and only old timers like myself have its documentation, you will hardly find anything about it on Apple's documentation nowadays.
