how to filter array model inside UISearchBar in swift 3

I have an array model which is like this:

 class Assess_order_med_model
{
    var name:String!
    var id:String!
    init(name:String!,id:String!) {
     self.name = name
        self.id = id
    }
}

and i want to filter my array based on the "id" .for this i am doing like this.

 var filteredData = [Assess_order_med_model]()
    override func viewDidLoad() {
        super.viewDidLoad()
        table_View.dataSource = self
        table_View.delegate  = self
        searchBar.delegate = self
        searchBar.showsCancelButton = false
        self.table_View.allowsSelection = false
        let array_vale1 = Assess_order_med_model.init(name: "New York, NY", id: "1")
               self.array_model.append(array_vale1)
                filteredData = array_model

    }

and now i am filtering my array like this

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {

        filteredData = searchText.isEmpty ? array_model : array_model.filter({(dataString: String) -> Bool in
            // If dataItem matches the searchText, return true to include it

            return dataString.range(of: searchText, options: .caseInsensitive) != nil
        })

        table_View.reloadData()
    }

but it is giving me error like this: value of type Assess_order_model has no member range. Can anyone help me what i am doing wrong while doing filtering?

Your array_model contains objects Assess_order_med_model, change your textDidChange searchText like below,

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    let searchString = searchText.trimWhiteSpace()
    if searchString != "", searchString.count > 0 {
        let filterData = array_model.filter {
            return $0.id?.range(of: searchString, options: .caseInsensitive) != nil
        }
    }
}

this is the generic method to trimWhiteSpace,

extension String {
    func trimWhiteSpace() -> String {
        let string = self.trimmingCharacters(in: .whitespacesAndNewlines)
        return string
    }
}
