Google place autocomplete in swift doesn't works perfectly - ios

Question

I tried to make "place autocomplete" from google place and I copy paste the codes directly from the website here google developer and I already set the api key too but the problem is why the results look so odd when I typing a place as you can see on the picture it seems works but not perfect. here is my code:
import UIKit
import GoogleMaps
class FetcherSampleViewController: UIViewController {
var textField: UITextField?
var resultText: UITextView?
var fetcher: GMSAutocompleteFetcher?
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.whiteColor()
self.edgesForExtendedLayout = .None
// Set bounds to inner-west Sydney Australia.
let neBoundsCorner = CLLocationCoordinate2D(latitude: -33.843366,
longitude: 151.134002)
let swBoundsCorner = CLLocationCoordinate2D(latitude: -33.875725,
longitude: 151.200349)
let bounds = GMSCoordinateBounds(coordinate: neBoundsCorner,
coordinate: swBoundsCorner)
// Set up the autocomplete filter.
let filter = GMSAutocompleteFilter()
filter.type = .Establishment
// Create the fetcher.
fetcher = GMSAutocompleteFetcher(bounds: bounds, filter: filter)
fetcher?.delegate = self
textField = UITextField(frame: CGRect(x: 5.0, y: 0,
width: self.view.bounds.size.width - 5.0, height: 44.0))
textField?.autoresizingMask = .FlexibleWidth
textField?.addTarget(self, action: "textFieldDidChange:",
forControlEvents: .EditingChanged)
resultText = UITextView(frame: CGRect(x: 0, y: 45.0,
width: self.view.bounds.size.width,
height: self.view.bounds.size.height - 45.0))
resultText?.backgroundColor = UIColor(white: 0.95, alpha: 1.0)
resultText?.text = "No Results"
resultText?.editable = false
self.view.addSubview(textField!)
self.view.addSubview(resultText!)
}
func textFieldDidChange(textField: UITextField) {
fetcher?.sourceTextHasChanged(textField.text!)
}
}
extension FetcherSampleViewController: GMSAutocompleteFetcherDelegate {
func didAutocompleteWithPredictions(predictions: [GMSAutocompletePrediction]) {
let resultsStr = NSMutableString()
for prediction in predictions {
resultsStr.appendFormat("%#\n", prediction.attributedPrimaryText)
}
resultText?.text = resultsStr as String
}
func didFailAutocompleteWithError(error: NSError) {
resultText?.text = error.localizedDescription
}
}
can anyone help me?

Answer 1

This is because prediction.attributedPrimaryText is an attributed string. Try the following code
func didAutocompleteWithPredictions(predictions: [GMSAutocompletePrediction]) {
let resultsStr = NSMutableAttributedString()
for prediction in predictions {
resultsStr.appendAttributedString(prediction.attributedPrimaryText)
resultsStr.appendAttributedString(NSAttributedString(string: "\n"))
}
resultText?.attributedText = resultsStr
}
