Ios 谷歌自动完成Swift UITextField

有没有人遇到过关于如何在UITextField上添加GoogleAutoComplete的资源。我只看过关于如何将搜索栏添加到导航控制器或过时且充满错误的教程。我想将其添加到UITextField。尚未在GitHub上找到任何适用于Swift 4的有效解决方案。

将GooglePlaces导入到您的文件中，然后将
UITextField
文本传递到此方法中：-

let placeClient = GMSPlacesClient.init()
let filter = GMSAutocompleteFilter()
filter.type = .establishment
filter.country = "in" //in for India (Only India address will be searched)
placeClient.autocompleteQuery("Pass your text here", bounds: nil, filter: filter) { (results, error) in
    if let err = error {
        print("Autocomplete error \(err)")
        return
    }
    if let results = results {
        // show result in your table view
    }
}

我在filter.type=.Establish上收到预期的声明错误
