Description
Calls to Objective-C methods defined outside the binary—e.g. NSString methods, etc.—currently can't be rewritten because there is no function inside the binary to replace the call destination with. Creating stub functions in a fake section for imported methods might allow for clearer decompilation.

Research direction
Start by tracing how external Objective-C method calls, such as NSString methods, are represented and where call destinations are rewritten. Investigate how stubs in a fake section could provide an in-binary destination, and define tests showing that imported method calls can be rewritten and produce clearer decompilation.
