I think I've answered my own question. You need to initialize the variable
to the type of the object that is needed. For example,

        templateDate = NSObject.alloc.init
        errorString = NSString.alloc.init
        conversionResult = dateFormatter.getObjectValue_forString_errorDescription(templateDate, @fpDate.stringValue, errorString)

At least, it works and my app doesn't crash any more. That's good enough
for me.
