`Property` 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 in the Realm.
|
|
|
|
When using Realm, property instances allow performing migrations and introspecting the database's schema.
|
|
|
|
Property instances map to columns in the core database.
