How to add google places autocomplete to xcode with swift (tutorial)

For Swift 3:

1- Select your podfile and type : pod 'GooglePlaces'

2- In the appDelegate, add your API Key : GMSPlacesClient.provideAPIKey("YOUR KEY") (Import the GooglePlaces)

3- Use this code in your viewController that contains the googleMap:

    // This code snippet demonstrates adding a// full-screen Autocomplete UI controlimport UIKitimport GooglePlacesclass ViewController: UIViewController {  // TODO: Add a button to Main.storyboard to invoke onLaunchClicked.  // Present the Autocomplete view controller when the button is pressed.  @IBAction func onLaunchClicked(sender: UIButton) {    let acController = GMSAutocompleteViewController()    acController.delegate = self    present(acController, animated: true, completion: nil)  }}extension ViewController: GMSAutocompleteViewControllerDelegate {  // Handle the user's selection.  func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {    print("Place name: \(place.name)")    print("Place address: \(place.formattedAddress)")    print("Place attributions: \(place.attributions)")    dismiss(animated: true, completion: nil)  }  func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {    // TODO: handle the error.    print("Error: \(error)")    dismiss(animated: true, completion: nil)  }  // User cancelled the operation.  func wasCancelled(_ viewController: GMSAutocompleteViewController) {    print("Autocomplete was cancelled.")    dismiss(animated: true, completion: nil)  }}

Not exactly tutorials, but there are a few resources on Github, with people providing libraries and code samples to achieve what you're asking for.

• SPGooglePlacesAutocomplete (https://github.com/spoletto/SPGooglePlacesAutocomplete) is very popular and has many features, but it's written in Objective-C
• iOS Google Places Autocomplete (https://github.com/watsonbox/ios_google_places_autocomplete) is more recent, written in Swift, and also contains some examples.
• lots of others...

Even without proper tutorials, you can still check out these libraries and understand how their code works to get some inspiration if you want to write your own components.

As a sidetone, Google also has this page, but it's not a dedicated tutorial for iOS apps, just some useful explanations of how their API works: https://developers.google.com/places/documentation/autocomplete#examples

You can try one for wrapper to implement Autocompletion for Place API with Google:

https://github.com/mrugrajsinh/MVAutocompletePlaceSearchTextField

Its very simple drop-in control and subclass of UITextField so using by binding Class with simple UITextField you can achive Auto completion dropdown similar as Uber and many popular app does.
