No, the other Objective-C files do not have this problem.

Not having much experience with Objective-C, I can't say.  But I think
code like this:

      [scriptor addUserScript:[[WKUserScript alloc]
                                initWithSource:xwScript
                                 injectionTime:
                                  WKUserScriptInjectionTimeAtDocumentStart
                                forMainFrameOnly:NO]];

has to be modified to keep track of the allocated WKUserScript
objects, and to call release on them when necessary.
