试试下面的 Swift 代码:-
import UIKit

let filter = GMSAutocompleteFilter()
filter.type = .establishment
fetcher = GMSAutocompleteFetcher(bounds: bounds, filter: filter)
fetcher?.delegate = self
txtField?.addTarget(self, action: #selector(textFieldDidChange(textField:)),for: .editingChanged)
tableView.delegate = self
tableView.dataSource = self
self.tableView.reloadData()
// Do any additional setup after loading the view.
}
@objc func textFieldDidChange(textField: UITextField) {
fetcher?.sourceTextHasChanged(txtField.text!)
}

return tableData.count

}

}
