C++17 minimum deployment target


Hi fellow developers,

Does anybody know what is the minimum deployment target in order to support c++17 and its standard library (std::clamp FTW) on OSX ?

Thanks !


std::clamp is a function template. It should be defined entirely in the header, i.e. it shouldn’t rely on any library support from the OS. The same applies to std::optional and std::variant. However, it doesn’t apply to other parts of the standard library, like std::filesystem, but I don’t know which macOS version supports them.


I believe it’s 10.7


for c++11, it’s true. Pretty sure this is not true for C++17 though hence my question for someone with the knowledge


Xcode 10.1 with the 10.14 SDK doesn’t have support of all C++17 library features. So a minimum deployment target that supports all of C++17 simply doesn’t exist.

You need to decide what exactly you want to use from C++17 and then we can try to figure out what the minimum deployment target is.


well it’s mostly cpp14 with some minor stuff from cpp17 like clamp which is indeed header only so I am probably safe with cpp14 only which looks like to require 10.9
