No suitable mapping model found for core data migration

Question

I\'m trying to perform an iOS Core Data migration that requires a MappingModel. Core data is not able to use the mapping model for some reason and it falls back to an automa

Had the same issue. I deleted an entity and renamed the relationship fields accordingly. I first tried to used lightweight migration and therefore specified renaming IDs for the relationships. Due to an oversight I mixed up the fields used for the "Renaming ID" and the "Hash Modifier". Once corrected everything works as expected.
