Fix the darwin fwk compile

[sagar-apple]

Problem

The Darwin CHIP.framework doesn't compile anymore.

Summary of Changes

Looks like #2273 (cc2423adc79698f0a55350e0d53d0e32600a650e) needed to also scope the vector usage in objc to std::vector.

FYI I’m merging this in, it’s been delayed in review and the build is broken right now.
