Answer / Arvind Kumar Gautam
"In Apple iOS, a Singleton is a design pattern that ensures a class has only one instance and provides a global access point to it. It is useful for creating objects that need to be accessed across an application or when you want to centralize some functionality. You can create a singleton in Objective-C by defining a private sharedInstance method, making the constructor private, and providing a public static method to access the shared instance."n
