Fatal error: use of unimplemented initializer in custom navigationcontroller

Question

I\'m creating a custom navigation controller. I have something like this:

public class CustomNavigationController: UINavigationController {

    // MARK: - L         


        

Answer 1

I had this issue happen to users on iOS 12.4, so to do a workaround in my custom initializer I did something like this:

init(rootViewController: UIViewController, numberOfPages: Int) {
    self.numberOfPages = numberOfPages
    if #available(iOS 13.0, *) {
        super.init(rootViewController: rootViewController)
    } else {
        super.init(nibName: nil, bundle: nil)
        self.viewControllers = [rootViewController]
    }
}

I basically initialize my class differently for every iOS version below 13. This does seem like the shortest solution.
