voidviewDidLoad

voidviewDidLoad is a method in the UIKit framework used in iOS application development with Swift or Objective-C. It belongs to the UIViewController class and serves as a lifecycle event that is called after the view controller has loaded its view hierarchy into memory. This method is commonly overridden by developers to perform additional setup tasks that are necessary once the view is available but not yet presented on the screen.

When a view controller is instantiated and its view is loaded, the system automatically invokes the voidviewDidLoad method. Inside its implementation, developers typically initialize data sources, configure user interface elements, set up observers, or prepare elements that do not depend on the view’s final size or position. It is important to call the superclass implementation within overridden methods to ensure proper functioning.

The voidviewDidLoad method is called only once during the lifecycle of a view controller, making it an ideal place for one-time setup activities. It is different from other lifecycle methods like viewWillAppear or viewDidAppear, which are triggered each time the view appears on screen.

The naming of the method as "voidviewDidLoad" appears unconventional and is likely a typographical or formatting error. The correct method name in UIKit is "viewDidLoad," which has no return value (void). Proper usage involves overriding the standard "viewDidLoad" method without parameters to customize its behavior.

In summary, viewDidLoad is a foundational method for initializing a view controller’s interface and data, essential for setting up the environment prior to the view’s presentation to the user.
