visage|SDK does not currently provide direct support for React Native.
For users willing to experiment, there is an undocumented workaround that allows use of visage|SDK in React Native.
visage|SDK is implemented in C++ and provides C++ API, therefore direct calls from React Native are not possible without a wrapper with C-interface functions. Example of such a wrapper is provided in visage|SDK in the form of VisageTrackerUnity Plugin which provides simpler, high-level API through a C-interface. It is intended for integration with Unity3D (in C# with P/Invoke), however it can also be used by other applications/languages that support importing and calling C-functions from a native library, including React Native.
Can I use visage|SDK with Swift?
visage|SDK does not currently provide a Swift API.
visage|SDK is implemented in C++ and provides C++ API which cannot be used directly in Swift without first wrapping C++ API in an NSObject and exposing it to Swift through bridging-header. Wrapping in an NSObject does not have to be one-on-one mapping with C++ classes, instead it can be a higher level mapping and fragments of source code from provided iOS sample projects can be used as building blocks.
General example how this technique is usually implemented can be found here:
