What you are looking for is to
savein Core Data after all 100 objects have been inserted as opposed to after each insert.When objects are inserted into Core Data they are only present in memory. To persist your new objects to disc you should save which will take all changes (inserts, updates and deletes) and write them to disc together.
If you look at the documentation for -insertObject (below) you can read that inserting an object only registers the object for being inserted when changes are saved.
By further looking at the documentation for -save: (below) you will se that it will (attempt to) save all the unsaved changed, in your case all 100 inserted items.
