iCDump is a modern and cross-platform Objective-C class dump. Compared to existing tools, iCDump can run independently from the Apple ecosystem and it exposes Python bindings.
It relies on LIEF to access the Objective-C metadata and LLVM to output the results.
Swift support is on-going but not public yet.
iCDump exposes a Python API through nanobind. One can dump Objective-C metadata as follows:
import icdump
metadata = icdump.objc.parse("./RNCryptor.bin")
print(metadata.to_decl())@interface RNCryptor.RNCryptor.Encryptor{
NSObject * encryptor;
}
@end
@interface RNCryptor.RNCryptor.Decryptor{
NSObject * decryptors;
NSObject * buffer;
NSObject * decryptor;
NSObject * password;
}
@end
...
Or inspect Objective-C structures using the different properties:
for cls in metadata.classes:
print(cls.demangled_name)
for prop in cls.properties:
print(prop.name)
