If you want to class-dump private frameworks, you can either install Xcode and class-dump the frameworks on your Mac using the above tools, or you can use classdump-dyld, which works right on your device (classdump-dyld can also be installed via its package hosted on BigBoss). (class-dump may produce better headers than class-dump-z for recent binaries.) This allows for an analysis of what methods exist in the executable, which can help you guess which ones to hook to get given functionality.Īll default (private and public) libraries on iOS are combined into a big cache file to improve performance in /System/Library/Caches//dyld_shared_cache_armX (see dyld_shared_cache for more details). It also comes with a splendid writeup on ObjC/Swift class-dumping: class-dump, class_dump_z, classdump-dyldįrom a given executable, class-dump and class_dump_z will generate header files with class interfaces.
