Google AutoComplete Not Populating TableView

Question

I am using Google AutoComplete to search Addresses. I am getting a result in the console, however, this is not populating into the TableView.

I am in the main queue when reloading the table.
I am getting a print count of the number of objects in the result.

SearchResultsController

extension ResultsController: UISearchResultsUpdating, UISearchControllerDelegate {

    func updateSearchResults(for searchController: UISearchController) {
        searchController.hidesNavigationBarDuringPresentation = false
        searchController.searchBar.autocorrectionType = .yes
        if searchController.isActive {
            searchController.searchResultsController?.view.isHidden = false
        }
        if searchController.searchBar.text == "" {
            self.searchResults.removeAll()
        } else {
            guard let query = searchController.searchBar.text else { return }
            GMSPlacesClient.shared().autocompleteQuery(query, bounds: nil, filter: self.filteredResults) { (results, error) in
                if error != nil {
                    print(error as Any)
                    return
                } else {
                    guard let results = results else { return }
                    self.searchResults.append(contentsOf: results)
                    print(self.searchResults)
                }
            }
            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        }
    }

    func didDismissSearchController(_ searchController: UISearchController) {
        searchResults.removeAll()
    }
}

TableView

extension ResultsController: UITableViewDelegate, UITableViewDataSource {

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return searchResults.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let resultsCell = tableView.dequeueReusableCell(withIdentifier: resultsCellIdentifier, for: indexPath)
        let resultsAttributedFullText = searchResults[indexPath.row].attributedFullText.string
        resultsCell.textLabel?.text = resultsAttributedFullText
        return resultsCell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        view.endEditing(true)
    }

Console Output

[GMSAutocompletePrediction 0x60000053d6e0: "Whittier Boulevard, Whittier, CA, USA", id: EiVXaGl0dGllciBCb3VsZXZhcmQsIFdoaXR0aWVyLCBDQSwgVVNBIi4qLAoUChIJ988tx8bTwoARp1jTzq6WINISFAoSCfeHelWG08KAEVokQMFHfagn, types: (

Any help greatly appreciated.

Update

Above is the breakpoint on .reloadData() on the tableView.
Therefore, the table is being reloaded and the array is being populated with the results. The issue is cellForRowAtIndex isnt being called for some reason!?

You do not need to add your tableview Please check below code

import GooglePlaces
import GoogleMaps

class DirectionsViewController: UIViewController, GMSAutocompleteViewControllerDelegate {

    let filter = GMSAutocompleteFilter()

    override func viewDidLoad() {
        super.viewDidLoad()
        txfFromLocation.addTarget(self, action: #selector(autocompleteClicked), for: .editingDidBegin)
    }

    @objc func autocompleteClicked (sender:UITextField!){
        let autocompleteController = GMSAutocompleteViewController()
        autocompleteController.delegate = self
        present(autocompleteController, animated: true, completion: nil)
    }

    //MARK:- GMSAUTOCOMPLETEDELEGATES
    // Handle the user's selection.
    func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        print("Place name: \(place.name)")
        dismiss(animated: true, completion: nil)
    }
}

I believe this is for Googles' "out of the box" UI. I require a customised UI. – David Henry Dec 28 '18 at 12:39
yes.. ok. Will let you know if I find anything as your requirement – Yogesh Tandel Dec 28 '18 at 12:40
Looking at your code. I see tableview.delegate = self and tableview.datasource = self is missing – Yogesh Tandel Dec 28 '18 at 12:53
I have that in my ViewDidLoad – David Henry Dec 28 '18 at 12:54
Try adding it to --- DispatchQueue.main.async { tableview.delegate = self tableview.datasource = self self.tableView.reloadData() } – Yogesh Tandel Dec 28 '18 at 12:55
It hasn't had any effect. – David Henry Dec 28 '18 at 12:58
Try adding a debug to check if the tableview code is executed and if the debug is coming to numberOfRowsInSection – Yogesh Tandel Dec 28 '18 at 13:00
for some reason cellForRowAtIndexPath isnt getting called. – David Henry Dec 28 '18 at 13:15
try moving your tableview code to the main viewcontroller. The problem is reloadData() function is not working – Yogesh Tandel Dec 28 '18 at 13:19
The problem is reload data is being called before the data in searchResults is fully loaded. Try to add a delay before a reloaddata function is called. just a timebeing solution so that we know the exact error – Yogesh Tandel Dec 28 '18 at 13:25
Can you elaborate? I have a main view controller "MapController" with searchController "ResultsController" My tableView is in the Results Controller because thats where the results will load. – David Henry Dec 28 '18 at 13:27
DispatchQueue.main.asyncAfter(deadline: .now() + 5) { // change 2 to desired number of seconds self.tableView.reloadData() } – Yogesh Tandel Dec 28 '18 at 13:28
I've added this with no effect. – David Henry Dec 28 '18 at 14:16
