If you choose an “advanced” build type in the Mendix Native App Builder, you can build the app locally and include this library in xcode. However, since Mendix Native apps are based on React Native, if you wanted to actually interact with this library at all, you’d likely need to define a React Native “wrapper” module to expose the library’s functions to the Mendix app’s React Native context.
There’s currently an open issue on the InTune App SDK github asking for React Native support, and there’s at least one attempt at “wrapping” the library that’s linked, but I can’t vouch for it’s quality.
I hope this helps. In the meantime, is there a particular feature from the InTune SDK that you’re hoping to support? Maybe there’s an alternative solution for what you need..
