Is it ok to cast a NSdictionary object to NSMutableDictionary?

Is it ok to cast a NSdictionary object to NSMutableDictionary?

NSDictionary *dict;
NSMutableDictionary *mDict = (NSMutableDictionary *)dict;

Tried this and it worked fine.

No it is not. If you want a mutable dictionary, make one:

NSMutableDictionary* mutableDict = [dict mutableCopy];

Do not forget in accordance with the rules you own mutableDict and must release it when you are done with it.
