How to preload all views once accessed view controller?

I have a series of view controllers and views. This is so I can swipe horizontally through my views.

Each view controller is essentially a different category. So my home screen has 4 buttons that each go to a different view controller. Each view controller has 6 views.

My question - when I go into the view controller, how can I get it to preload all the views in that view controller?

My views are webviews, so I want them to all start loading as soon as I hit the button on my homescreen and go into the view controller. Otherwise I wait for view 1 to load, swipe to view 2, wait for that, swipe to view 3, wait for that etc. So ideally once you wait for view 1 to load, all the others have loaded as well.

This is my current websetup that is in every view:

    // Websetup
        let productionURL = URL(string:"https://docs.google.com/")
    let productionURLRequest = URLRequest(url: productionURL!)
    webview1.loadRequest(productionURLRequest)

Could I perhaps call all load requests for the views in the above code?

If you have your request code in the viewDidLoad function of the view controllers, you can force the view to load by referencing viewController.view. So you can do something like let _ = myViewController.view for each one of them when you first initialize them. You can also just break the request loading into a separate function and call that in the exact same way explicitly (and also right after you initialize them).
