4,107 Pointsno visible @interface for 'NSMutableDictionary' declares the selector 'addEntriesFromDictionary'
I am trying to enter the body of the 'addMenuChoice' method in the CateringOrder class but when I try to enter this line of code: [self.orderFormDict addEntriesFromDictionary:@{menuItem.itemName:@0}];
It gives me the error: "no visible @interface for 'NSMutableDictionary' declares the selector 'addEntriesFromDictionary'"
I double checked my code to make sure I entered it like you did, but can't seem to figure out what is causing.
Please help!

NSMutableDictionary *orderFormDict = [[NSMutableDictionary alloc] init];
// In another method
[self.orderFormDict addEntriesFromDictionary:@{menuItem.itemName:@0}];

1,734 PointsI also had the same issue but finally I noticed that I mistyped in CeteringOrder.h in properties I typed @property (nonatomic, strong) NSMutableArray* orderFormDict; instead of @property (nonatomic, strong) NSMutableDictionary* orderFormDict that is why there was no visible interface in my case.
Always check Your code for mistypings, because sometimes I am spending hours searching for a complex solutions to my issue and finally the mistake is simply mistyping.
Hope that helps.
Happy coding!
