问题
I have created a core data model and when trying to save records I get the following console message: Unresolved error Error Domain=NSCocoaErrorDomain Code=134100 "The operation couldn’t be completed. (Cocoa error 134100.)" UserInfo=0x8b3bc50 {metadata={
NSPersistenceFrameworkVersion = 479;
NSStoreModelVersionHashes = {
};
NSStoreModelVersionHashesVersion = 3;
NSStoreModelVersionIdentifiers = (
""
);
NSStoreType = SQLite;
NSStoreUUID = "F49C0E04-9778-46EC-A9C7-9A045CD915D8";
"_NSAutoVacuumLevel" = 2;
}, reason=The model used to open the store is incompatible with the one used to create the store}, {
metadata = {
NSPersistenceFrameworkVersion = 479;
NSStoreModelVersionHashes = {
};
NSStoreModelVersionHashesVersion = 3;
NSStoreModelVersionIdentifiers = (
""
);
NSStoreType = SQLite;
NSStoreUUID = "F49C0E04-9778-46EC-A9C7-9A045CD915D8";
"_NSAutoVacuumLevel" = 2;
};
reason = "The model used to open the store is incompatible with the one used to create the store";
}
I am not sure where to start to debug it please can someone tell me where the problem could be as I am new to core data.

Remove your app from the simulator or device, clean the project and run it again.
Update: Do this only for development stages and be sure to understand the model versioning like Patrick Goley stated below.
