Cannot explicitly specialize a generic function

Question

}
         


        

Answer 1

The solution is taking the class type as parameter (like in Java)

To let compiler know what type he is dealing with pass the class as argument

extension UIViewController {
    func navigate(_ dump: ControllerType.Type, id: String, before: ((ControllerType) -> Void)?){
        let controller = self.storyboard?.instantiateViewController(withIdentifier: id) as! ControllerType
        before?(controller)
        self.navigationController?.pushViewController(controller, animated: true)
    }
}

Call as:

self.navigate(UserDetailsViewController.self, id: "UserDetailsViewController", before: {
        controller in
        controller.user = self.notification.sender
    })
