Подкласс GMSAutocompleteViewController использовать его с Eureka

Question

Я пытаюсь создать подкласс GMSAutocompleteViewController форму GooglePlaces SDK, как это:

class AddressFinderViewController: GMSAutocompleteViewController, TypedRowControllerType { 

public var row: RowOf<String>! 
public var completionCallback : ((UIViewController) ->())? 



convenience public init(_ callback: (UIViewController) ->()){ 
    self.init(nibName: nil, bundle: nil) 
    completionCallback = callback 
} 



override func viewDidLoad() { 
    super.viewDidLoad() 

     } 
    } 

Затем я использую это назвать:

AddressFinderViewController(){ _ in } 
      }, completionCallback: { vc in 
       vc.navigationController?.popViewControllerAnimated(true) 
     } 

Но я получаю эту ошибку :

Answer 1

Возможно, вам потребуется позвонить по телефону super.init() в AddressFinderViewController, чтобы убедиться, что GMSAutocompleteViewController инициализирован правильно.
