我正在使用 GMSAutocompleteViewController GMSAutocompleteViewController 专用码 和google places googleplacepicker 有了它,我添加了它,但仍然崩溃了

GMSPlacePickerViewController 所有这些都是在将pod更新到2.4之后开始的,我试图回滚到2.3.1,但还是崩溃了

let autocompleteController = GMSAutocompleteViewController()
    autocompleteController.delegate = self
    present(autocompleteController, animated: true, completion: nil)

我打开了一个新项目,并将代码转移到其中 以下是调用堆栈:
