why `ipsw` isn't able to locate the symbol for the NSObject class

          TL;DR: we need to find out why `ipsw` isn't able to locate the symbol for the NSObject class. If that's a blocker for this PR, it's up to you. The generated code will compile just fine with the `@class NSObject;` statements.
