ios – Core Information Migration Mapping Mannequin createRelationships crash

July 19, 2024

I’ve created a heavyweight migration between two database variations utilizing a mapping mannequin & customized coverage. Three sorts are migrated throughout this migration map.

Nonetheless, one (or probably extra) sorts that shouldn’t have a customized coverage (i.e. utilizing the default migration mappings for relationships) are crashing throughout the createRelationships a part of the migration.

Deadly Exception: NSInvalidArgumentException

Unlawful try to ascertain a relationship 'Y' between objects in numerous contexts (supply = <NSManagedObject: 0x301149ea0> (

  kind = a; 
  consumer = nil; 
}) , vacation spot = <NSManagedObject: 0x3011193b0> (

information: <fault>))

Anybody have any concepts? Since I am not touching these sorts within the migration map with a customized coverage, I am undecided the way to resolve this one.
