过滤google地方API搜索结果iOS swift

Question

我希望过滤我的附近位置搜索只能在谷歌地方API搜索google网站https://developers.google.com/places/supported_types中的swift I found标签，但我不知道如何实现这些标签任何帮助将不胜感激。

import UIKit
import GooglePlaces

class PlacesViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!

// An array to hold the list of possible locations.
var likelyPlaces: [GMSPlace] = []
var selectedPlace: GMSPlace?

// Cell reuse id (cells that scroll out of view can be reused).
let cellReuseIdentifier = "cell"

override func viewDidLoad() {
super.viewDidLoad()

// Register the table view cell class and its reuse id.
tableView.register(UITableViewCell.self, forCellReuseIdentifier: 
cellReuseIdentifier)

// This view controller provides delegate methods and row data for the 
table view.
tableView.delegate = self
tableView.dataSource = self

tableView.reloadData()
}

// Pass the selected place to the new view controller.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "unwindToMain" {
  if let nextViewController = segue.destination as? MapViewController {
    nextViewController.selectedPlace = selectedPlace
  }
 }
 }
 }

// Respond when a user selects a place.
extension PlacesViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: 
IndexPath) {
selectedPlace = likelyPlaces[indexPath.row]
performSegue(withIdentifier: "unwindToMain", sender: self)
}
}

// Populate the table with the list of most likely places.
extension PlacesViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: 
Int) -> Int {
return likelyPlaces.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: 
IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: 
cellReuseIdentifier, for: indexPath)
let collectionItem = likelyPlaces[indexPath.row]

cell.textLabel?.text = collectionItem.name

return cell
}

// Adjust cell height to only show the first five items in the table
// (scrolling is disabled in IB).
func tableView(_ tableView: UITableView, heightForRowAt indexPath: 
IndexPath) -> CGFloat {
return self.tableView.frame.size.height/5
}

 // Make table rows display at proper height if there are less than 5 
 items.
 func tableView(_ tableView: UITableView, heightForFooterInSection 
section: Int) -> CGFloat {
if (section == tableView.numberOfSections - 1) {
  return 1
}
return 0
}
}
