This is the Objective-C equivalent of CL 34776, generating reverse
wrappers for generated ObjC types. The implementation follows the same
strategy as the Java implementation: use the Go ast package to find
exported structs with embedded Objective-C types and synthesize their
types as if they were imported through clang.
In turn, the handling of the implicit "self" parameter changes in the
same way as well: the type of self parameters must be the wrapped type
for the generated type. For example:
func (d *GoNSDate) Description(self Foundation.NSDate) string
becomes
import gopkg "ObjC/Objcpkg"
func (d *GoNSDate) Description(self gopkg.GoNSDate) string

Accept ObjC API wrapper types as arguments and return values from
bound Go package functions and methods. Also, allow Go structs
to extend ObjC classes and implement ObjC protocols as well as override
and implement methods.
This is the third and final part of the implementation of the golang/go#17102
proposal.
