如何在swift中分离google place picker api中的国家和地址

import UIKit
import GooglePlaces

class ViewController: UIViewController, GMSPlacePickerViewControllerDelegate {
    
    // 创建一个按钮，用于触发显示Place Picker
    let placePickerButton = UIButton(type: .system)
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置按钮的标题和位置
        placePickerButton.setTitle("选择地点", for: .normal)
        placePickerButton.frame = CGRect(x: 0, y: 0, width: 200, height: 50)
        placePickerButton.center = view.center
        placePickerButton.addTarget(self, action: #selector(showPlacePicker), for: .touchUpInside)
        
        // 将按钮添加到视图中
        view.addSubview(placePickerButton)
    }
    
    @objc func showPlacePicker() {
        // 创建Place Picker的配置
        let config = GMSPlacePickerConfig(viewport: nil)
        
        // 创建Place Picker视图控制器
        let placePicker = GMSPlacePickerViewController(config: config)
        placePicker.delegate = self
        
        // 呈现Place Picker视图控制器
        present(placePicker, animated: true, completion: nil)
    }
    
    // 处理用户选择的地点
    func placePicker(_ viewController: GMSPlacePickerViewController, didPick place: GMSPlace) {
        // 获取地点的国家和地址信息
        let country = place.addressComponents?.filter({ $0.types.contains("country") }).first?.name ?? ""
        let address = place.formattedAddress ?? ""
        
        // 打印国家和地址信息
        print("国家：\(country)")
        print("地址：\(address)")
        
        // 关闭Place Picker视图控制器
        viewController.dismiss(animated: true, completion: nil)
    }
    
    func placePickerDidCancel(_ viewController: GMSPlacePickerViewController) {
        // 用户取消选择地点，关闭Place Picker视图控制器
        viewController.dismiss(animated: true, completion: nil)
    }
}
