Handle annoying operations of objects in Realm DB

Problem

Update value of object in Realm DB is annoying because the task should be within a writing transition.

Solution

Extend the Realm’s Object class to provide convient methods to do these things:

update: to set/update properties’ values.
remove: to remove object from Realm

// RealmHelper.swift
import RealmSwift

extension Object {
    // Update property value in Realm
    func update(_ property: String, value: Any?) {
        let realm = try! Realm()
        try! realm.write {
            self.setValue(value, forKey: property)
        }
    }
    
    // Remove object from Realm
    func remove() {
        let realm = try! Realm()
        try! realm.write {
            realm.delete(self)
        }
    }
}
