Can someone point me to the design of how swig is being used in ITK/SimpleITK? Or explain that succinctly in terms of the architecture, merits and limitations?
I asked a similar question about vtk not knowing that SWIG isn’t used in vtk.

I have found an useful document here: [https://data.kitware.com/#collection/57b5c9e58d777f126827f5a1/folder/57b5ddb98d777f10f2695fb0](https://data.kitware.com/#collection/57b5c9e58d777f126827f5a1/folder/57b5ddb98d777f10f2695fb0)
I attach pdf: [SimpleITK-MICCAI-2011.pdf](https://discourse.itk.org/uploads/short-url/qVhwgDuAmrMlAAp6jOfpBdvayXv.pdf) (2.5 MB)
I hope to help you.
