How to get selected place coordinates in google places autocomplete prediction in table view ios swift

Question

i am able to get google places auto complete results in table view using below code. now i am looking for how to get coordinate of selected place of tableview?

 func didAutocomplete(with predictions: [GMSAutocompletePrediction]) {
    tableData.removeAll()

    for predicition in predictions
    {
         tableData.append(predicition.attributedFullText.string)
    }
    table1.reloadData()
}

Like if i select the row of table view then below method get invoked and i want to get coordinates of that particular place

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

}

From the GMSAutocompletePrediction, you will get a placeID, which is a textual identifier that uniquely identifies a place. To get a place by ID, call GMSPlacesClient lookUpPlaceID:callback:, passing a place ID and a callback method.

So you need to declare another global array for saving placesID. Or you can use one array for saving a GMSAutocompletePrediction object; extract the attributedFullText in the cellForRowAtIndexPath for populating the labels and extract the placeID in didSelectRow.

Let say your tableData is an array of GMSAutocompletePrediction object.

var tableData = [GMSAutocompletePrediction]()

Then your didAutocomplete delegate method will be like this

func didAutocomplete(with predictions: [GMSAutocompletePrediction]) {
    tableData = predictions
}

And your cellForRowAtIndexPath will be :-

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    /* Intitialise cell */

    let predictionText = tableData[indexPath.row]attributedFullText.string
    print(“Populate \(predictionText) in your cell labels”)

    /* Return cell */
}

And your didSelectRowAt will be :-

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let prediction = tableData[indexPath.row]

    if let placeID = predicition.placeID {
        let placesClient = GMSPlacesClient.shared()
        placesClient.lookUpPlaceID(placeID) { (place, error) in
            if let error = error {
                print("lookup place id query error: \(error.localizedDescription)")
                return
            }

            guard let place = place else {
                print("No place details for \(placeID)")
                return
            }

            let searchedLatitude = place.coordinate.latitude
            let searchedLongitude = place.coordinate.longitude
        }
    }
}
