How can you translate an application from active mode to inactive?

In iOS, the application lifecycle and the UIApplicationDelegate methods are used to transition the app from active to inactive state.

When the app moves to an inactive state (for example, during an incoming call or when the Home button is pressed), the following method is called:

func applicationWillResignActive(_ application: UIApplication) {
    // Pause tasks, disable timers, etc.
}

After this, the app may also transition to the background with the call of:

func applicationDidEnterBackground(_ application: UIApplication) {
    // Release resources, save data
}

Therefore, to transition the app to an inactive state, it is necessary to correctly handle these methods and manage states within them.
