what correct approach lazy loading coredata relationships? say have project object , projectfilter object may or may not exist, work expected? - (projectfilter *)filter { [self willaccessvalueforkey:@"filter"]; projectfilter *filter = [self primitivevalueforkey:@"filter"]; [self didaccessvalueforkey:@"filter"]; if (!filter) { filter = [nsentitydescription insertnewobjectforentityforname:@"projectfilter" inmanagedobjectcontext:self.managedobjectcontext]; self.filter = filter; } return filter; } this terrible idea , shouldn't it. in simple core data stack can have running on main thread. app gets more complex need have background context. if have multiple context writing core-data @ same time can merge conflicts. can tell core-data auto-resolve merged conflicts - isn't great solution because guaranteed lose data way. common solution have single queue writing , use main thread...
