Storyboards

Programmatically

Setting the presentation controller manually with UIViewControllerTransitioningDelegate

import BlurPopover

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func presentViewController(_ sender: UIButton) {
        let dvc = CustomViewController()
        dvc.modalPresentationStyle = .custom
        dvc.transitioningDelegate = self
        present(dvc, animated: true)
    }
}

extension ViewController: UIViewControllerTransitioningDelegate {
    func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController? {
        BlurPopoverPresentationController(presentedViewController: presented, presenting: presenting)
    }
}

Inheriting the base class BlurPopoverBaseViewController

import BlurPopover

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func presentViewController(_ sender: UIButton) {
        let dvc = CustomViewController()
        present(dvc, animated: true)
    }
}

class CustomViewController: BlurPopoverBaseViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

Using the shared delegate BlurPopoverSharedTransitioningDelegate

import BlurPopover

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func presentViewController(_ sender: UIButton) {
        let dvc = CustomViewController()
        dvc.modalPresentationStyle = .custom
        
        // source will animate from the view when presenting
        // destination will animate to the view when dismissing
        dvc.transitioningDelegate = BlurPopoverSharedTransitioningDelegate.sharedDelegate(
            presentingSourceView: imageView,
            dismissingDestinationView: imageView
        )
        
        present(dvc, animated: true)
    }
}

class CustomViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}
