Using ObjectiveC Library in React Native

-

I'm trying to build a Chromecast App with React Native, and my options for the Chromecast library are either an ObjectiveC version.

With React Native, how would I get the ObjectiveC library into my React Native App?

The React Native documentation walks you through writing a native module to expose JavaScript functions that can call Objective-C methods: https://facebook.github.io/react-native/docs/nativemodulesios.html.

reinterpret_cast bug or UB? [duplicate]

This question already has an answer here: Observing weird behavior with 'auto' and std::minmax 1 answer structured bindings with std::minmax and rvalues 2 answers Consider following code: #include <cstdint> #include <algorithm> std::uintptr_t minPointer(void *first, void *second) { const auto pair = std::minmax( reinterpret_cast<std::uintptr_t>(first), reinterpret_cast<std::uintptr_t>(second) ); return pair.first; } and the assembly generated by GCC8 with -O3 on https://godbolt.org/z/qWJuV_ for minPointer: minPointer(void*, void*): mov rax, QWORD PTR [rsp-8] ret which clearly does not do what is intended by the code creator. Is this code causing some UB or is it GCC(8) bug? This is UB, but not for the reason you might think. The relevant signature o...
