Have you worked with Realm database in your projects?

Yes, Realm is a mobile database that is often used in iOS projects for local data storage. It is convenient because it operates quickly, supports reactive data updates, and does not require complex configuration, unlike Core Data.

Example of using Realm in iOS with Swift:

import RealmSwift

class Dog: Object {
    @objc dynamic var name = ""
    @objc dynamic var age = 0
}

let realm = try! Realm()

let myDog = Dog()
myDog.name = "Rex"
myDog.age = 1

try! realm.write {
    realm.add(myDog)
}

let dogs = realm.objects(Dog.self)
print(dogs)

Realm is well-suited for applications with offline mode and data synchronization.
