How to update a type of a realm model property in Objective c?

Question

I have a RLMObject in my Objective-c. I defined a property like:

 @property (assign, nonatomic) NSString *name;
 @property (assign, nonatomic) NSString *code;
 @property (assign, nonatomic) int day;
 @property (assign, nonatomic) int status;

But now, I need change the type of property code to int like:

 @property (assign, nonatomic) int code;

If I change this, then when I try access to the model I get an error showing that type was NSString and now int.

How can I change the property without reinstall my app?

You need to perform a migration so the data in the database fits the new data model. Please check the Migrations section of the Realm documentation.
