Swift crashing with two core data entities -

i have app set core info , 1 entity named "subject", when seek add together entity core info called "homework", app crashes , error

2014-10-04 12:41:05.302 homejournal[1050:20160] unresolved error optional(error domain=your_error_domain code=9999 "failed initialize application's saved data" userinfo=0x7fe6bb60cac0 {nslocalizedfailurereason=there error creating or loading application's saved data., nslocalizeddescription=failed initialize application's saved data, nsunderlyingerror=0x7fe6bb524760 "the operation couldn’t completed.

i'm not sure did wrong, have set info out of entity called "subject" using code

var appdel:appdelegate = (uiapplication.sharedapplication().delegate appdelegate) var context:nsmanagedobjectcontext = appdel.managedobjectcontext! var request = nsfetchrequest(entityname: "subject") request.returnsobjectsasfaults = false;

which works if there 1 entity. in advanced

as suggested in comment, seek deleting app simulator , re-install. if still fails match nsmanagedobject files created info models in actual info models. may case created files , changed models.

core-data swift entity
