Is it possible to write a C++ library that could be used in iOS and Android Native projects?

Question

I want to write an app for both platforms, and I want it to be a native.

Still, I would like to have a write once run anywhere conception. Since the business logic would take a huge part of an app. And it would be pretty simple regarding frameworks (mostly math calculations). I would like to move it into the common part of the app.

So my question is, are there any successful examples on C++ library that could be used for both native platforms?

Anything is possible in a Turing complete language like C++. — Jonathan Hall, Aug 29 '18 at 14:11
@Flimzy the question is not about C++, but about Android/iOS platform. Would they support such a library? — Taier, Aug 29 '18 at 14:13
The answer is the same. Both execute Turing-complete code, so of course it's possible to integrate them with C++ (or any other language). The interesting question would be: How easy is this? — Jonathan Hall, Aug 29 '18 at 14:16

Yes it is possible as iOS is capable of running c++ files and libraries and via the NDK Android is also capable of running c++ and c++ libraries.

There are plenty of resources online but you might find the following from Medium useful:

Be careful though as there will be a performance overhead and you have to be careful when compiling the builds if you want it to run on both an iOS device and also the simulator, you will need to create a fat binary as they are built on different chip architectures.
