Core Data and many Entity
- by mr.octobor
I'm newbie and I must save "Ranking" and "Level" of user.
I create file Ranking.xcdatamodel for save "Ranking"
with entity name Ranking (property is Rank, Name) I can save and show it.
but when I create entity Level (property is CurrentLevel) my program is crash and show this message
Unresolved error Error Domain=NSCocoaErrorDomain Code=134100 UserInfo=0x60044b0 "Operation could not be completed. (Cocoa error 134100.)", {
metadata = {
NSPersistenceFrameworkVersion = 248;
NSStoreModelVersionHashes = {

};
NSStoreModelVersionHashesVersion = 3;
NSStoreModelVersionIdentifiers = (

NSStoreType = SQLite;
NSStoreUUID = "41225AD0-B508-4AA7-A5E2-15D6990FF5E7";
"_NSAutoVacuumLevel" = 2;
};
reason = "The model used to open the store is incompatible with the one used to create the store";
}
I don't know how to save "Level"
please suggest me.
