Swift Remove Object from Realm

Question

I have Realm Object that save list from the JSON Response. But now i need to remove the object if the object is not on the list again from JSON. How i do that? This is my init f

What you can do is assign a primary key to the object you are inserting, and when receiving a new parsed JSON you verify if that key already exists or not before adding it.

class Items: Object {
    dynamic var id = 0
    dynamic var name = ""

    override class func primaryKey() -> String {
        return "id"
    }
}

When inserting new objects first query the Realm database to verify if it exists.

let repeatedItem = realm.objects(Items.self).filter("id = 'newId'")

if !repeatedItem {
   // Insert it
}
