I want to put an NSMutableDictionary into my standardUserDefaults

one of the checkboxes I find that NSNumber needs a setBoolValue
method to be KVC compliant.
So I need an object that is both property list compliant and KVC
compliant for a BOOL value.
Is there a standard workaround somewhere?
Are you binding to "foo.bar.boolValue"? You should just bind to
foo.bar.
Since an NSNumber is immutable, any request for a setBoolValue:
method raises a red flag -- why is something trying to modify an
NSNumber. That thing, whatever it is, should be trying to replace
that NSNumber.
