Truncate table in Realm Swift

Question

I am trying to delete all objects inside one class. I found two possibilities inside Realms documentation. First there's the possibility to use realm.deleteAll(), which deletes the whole database and there's realm.delete(), which deletes one single object. Is there a way to delete all entries inside one Table/Class in a easy way?

Answer 1

Suppose you want to delete all objects of Notofications,

you can try this

let realm = Realm()
    realm.write {
      let allNotifications = realm.objects(Notifications)
      realm.delete(allNotifications)
    }

Answer 2

Here's an extension that does this:

extension Object {
    static func deleteAll(`in` realm: Realm) throws {
        let allObjects = realm.objects(self)
        try realm.write {
            realm.delete(allObjects)
        }
    }
}
