Thanks, @GxocT for your workaround, however, the solution posted here is different from the one you posted on Reddit.

The one on Reddit works for me, this one doesn't so I want to repost it here. The difference is on the line with swizzledMethod which should be:

   let swizzledMethod = class_getInstanceMethod(object_getClass(self), swizzledSelector) {

The whole updated code is:

class MyClass: CNContactViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.changeImplementation()
    }

    func changeCancelImplementation() {

        let originalSelector = Selector(("editCancel:"))
        let swizzledSelector = #selector(CNContactViewController.cancelHack)

        if let originalMethod = class_getInstanceMethod(object_getClass(CNContactViewController()), originalSelector),
           let swizzledMethod = class_getInstanceMethod(object_getClass(self), swizzledSelector) {

            method_exchangeImplementations(originalMethod, swizzledMethod)
        }
    }

   func contactViewController(_ viewController: CNContactViewController, didCompleteWith contact: CNContact?) {
       // dismiss the contacts controller as usual
       viewController.dismiss(animated: true, completion: nil)
       // do other stuff when your contact is canceled or saved
       ...
    }
}

extension CNContactViewController {
    @objc func cancelHack()  {
        self.delegate?.contactViewController?(self, didCompleteWith: self.contact)
    }
}
