Ios App Life Cycle Swift

If you enable scene support in your app ios always uses your scene delegates in ios 13 and later.

Ios app life cycle swift. App delegate object manages your app s shared behaviors. The viewcontroller swift file contains the app s main view s life cycle method which will be triggered when the view state is changed this article will give you an example to tell you how the view life cycle methods are invoked. Respond to scene based life cycle events.

The typical life cycle of ios application starts with uiapplicationmain when we run the app first its object will create and initialized. The app not started or be stoped. It works in conjunction with uiapplication to manage some interactions with the system.

Once the object is created and initialized then the appdelegate swift is turn on and the uiapplication object will pointed to appdelegate swift file. The main point of entry into ios apps is uiapplicationdelegate. If your app supports scenes uikit delivers separate life cycle events for each.

In ios 12 and earlier use the uiapplication delegate object to respond to life cycle events. Not running state. Application lifecycle helps to understand overall app behaviour.

Your application is not running. How the application starts. App delegate object created when the app launched and object present in the whole application.

This is your application root object. Every ios application has five state in it s life cycle. In ios 12 and earlier the system uses your app delegate.
