I am building a framework in which I need to import some objective-c frameworks for now I need to import \"Beaconstac.framework\" but as we can not add a bridging header in
You need to import the Beaconstac framework in your umbrella header. That is, if you'd ordinarily use, e.g., #import
in an Obj-C bridging header, for a framework you need to put that in the umbrella header.
