predicate with avoid child entity iOS swift

 Problem:

I had my coredata entity that main entity had one level of subentity with the same entity.But in predicate i want to avoid the subentity entry but if subentity has the predicated text then main entity wants to be came.How can i achieve that?

Solution:

First you have to add issubentity in the coredata entity and enter if subentity then true otherwise it will be false.Then follow the below code.

                    predicateStringAdd.append(NSPredicate(format: "(time.startsOn >= %@ OR ANY subEntity.time.startsOn >= %@) AND isSubEntity != true",time1,time2))

the above will be based on start above start time and below endtime.

You can check with string as like below

                    predicateString.append(NSPredicate(format: "(name CONTAINS[c] %@ OR  ANY subEntity.name CONTAINS[c] %@ OR desc CONTAINS[c] %@ OR ANY subEntity.desc CONTAINS[c] %@ AND isSubEntity != true",trimmedString,trimmedString,trimmedString,trimmedString))
