RLMProperty

Objective-C

@interface RLMProperty : NSObject

Swift

class RLMProperty : NSObject

RLMProperty instances represent properties managed by a Realm in the context of an object schema. Such properties may be persisted to a Realm file or computed from other data from the Realm.

When using Realm, RLMProperty instances allow performing migrations and introspecting the database’s schema.

These property instances map to columns in the core database.
