title: Using C++17 to build ios apps?
body: <p>The latest XCode clang has support for c++17 but I'm not sure if older iOS devices (e.g., iPhone5, iPhone6) would have the <code>libc++</code> library to support that. Is there a way to find out if I can use C++17 to build ios apps that supports all supported iOS versions?</p>
  <p>Reference:
  iPhone5, with iOS12 is still supported
