how to fast add objective-c model

https://fbinfer.com/docs/adding-models.html

custom one model, need test, if build infer Every time，is very inconvenient.
if not build infer again, how can I test model.

if the command line can assign custom models directory,
or just build custom mode, then move to all models directory,
is very convenient.

thanks

Start with the adding models documentation at https://fbinfer.com/docs/adding-models.html and trace how custom Objective-C models are built and discovered from the command line. Determine whether a custom models directory or a model-only build path is feasible; done means a model can be tested without rebuilding all of Infer each time.
