ios - GMSAutoCompleteViewController 崩溃 - Swift 3

我最近将我的应用程序升级到了 swift 3，每当它尝试调用谷歌地图中的自动完成 View Controller 时，它就会崩溃。我知道 api key 不是问题，因为在我升级到 swift 3 和 xcode 8 之前使用它时它工作正常。我也知道这一点，因为该应用程序仍然能够显示谷歌地图。 这是我的代码:

extension AdditionalSetupViewController: GMSAutocompleteViewControllerDelegate {

    func  viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        let locationCoordinate = place.coordinate

        if homeClicked {
            homeAddress = [locationCoordinate.latitude, locationCoordinate.longitude]
        }

        else if homeAddress == [] {
        }

        else {

            let coordString = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".replacingOccurrences(of: ".", with: ",")

//            let coordString = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".stringByReplacingOccurrencesOfString(".", withString: ",")

            ref = FIRDatabase.database().reference()

            let currentUser: String = (FIRAuth.auth()?.currentUser?.uid)!
            let address = ref.child("schoolOrWorkAddress").child(coordString)
            let childUpdates = [currentUser: homeAddress]
            address.updateChildValues(childUpdates)

            finishButton.alpha = 1
            finishButton.isEnabled = true
        }

        let schoolorWorkCoords = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".replacingOccurrences(of: ".", with: ",")

//        let schoolorWorkCoords = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".stringByReplacingOccurrencesOfString(".", withString: ",")
        let userID = (FIRAuth.auth()?.currentUser?.uid)!
        _ = ref.child("posts").child(userID).key
        let additionalBasicInfo = ["schoolOrWorkAddress": schoolorWorkCoords, "homeAddress": homeAddress] as [String : Any]
        let usersRef = ref.child("users/\(userID)")
        usersRef.updateChildValues(additionalBasicInfo as [NSObject : AnyObject])

        self.dismiss(animated: true, completion: nil)

   }


    func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
        print(error)
    }

    func wasCancelled(_ viewController: GMSAutocompleteViewController) {
        self.dismiss(animated: true, completion: nil)
    }

    func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
    }

    func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
    }

}

这是错误输出:

如果这可能有帮助，我不知道，但这里也是我的 View Controller 其余部分的代码:

class AdditionalSetupViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {


    override func viewDidLoad() {
        finishButton.alpha = 0.4
        finishButton.isEnabled = false

        navigationController?.navigationBar.barTintColor = UIColor(red: 46, green: 204, blue: 113, alpha: 0)
    }


    @IBOutlet weak var mapView : GMSMapView!
    var homeClicked = false
    var homeAddress: [Double] = []

    @IBAction func addYourHomeAddress(sender: AnyObject) {
        homeClicked = true
        createGMSViewController()
    }

    @IBAction func addYourSchoolOrWorkAddress(sender: AnyObject) {
        homeClicked = false
        createGMSViewController()
    }

    func createGMSViewController() {
        let searchAutoCompleteController = GMSAutocompleteViewController()
        searchAutoCompleteController.delegate = self
        self.present(searchAutoCompleteController, animated: true, completion: nil)
    }

    @IBOutlet weak var finishButton: UIButton!

    @IBAction func finishButton(sender: AnyObject) {

        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

        let nextViewController = storyBoard.instantiateViewController(withIdentifier: "TableView") as! UITabBarController
        self.present(nextViewController, animated:true, completion:nil)

    }


}

我不知道为什么它在调用它时会崩溃，但我们将不胜感激!

好吧，事实证明，GMS 自动完成 View Controller 工作正常，但这是一个导出问题。解决方案是简单地删除您拥有的当前 xcode 7 或以前版本的 socket ，然后创建一个新的 socket ，因为 socket 在 xcode 8 中略有不同。
