Transformable attributes in Core Data
Read OriginalThis article details the use of Transformable attributes in Apple's Core Data framework. It explains that while standard types like strings and integers are straightforward, Transformable attributes allow storage of custom objects (like NSArray or custom classes) as long as they conform to the NSCoding protocol. The article also notes the limitation that these attributes are stored as binary data, making them unqueryable via NSPredicate.
