Prerequisites

1. Install pods in your project
2. Install the GooglePlaces SDK
3. Enable location services

First we need to get the users location by getting their current longitude and latitude.

1. Import GooglePlaces and GooglePlacePicker

import GooglePlaces
import GooglePlacePicker

2. Add the CLLOcationManagerDelegate protocol

class ViewController: UIViewController, CLLocationManagerDelegate {
    
}

3. create your CLLocationManager()

var currentLocation = CLLocationManager()

4. Request authorization

currentLocation = CLLocationManager()
currentLocation.requetAlwayAuthorization()

5. Create a button to call the GooglePlacePicker method

@IBAction func placePickerAction(sender: AnyObject) {

if CLLOcationManager.authorizationStatues() == .AuthorizedAlways {

        let center = CLLocationCoordinate2DMake((currentLocation.location?.coordinate.latitude)!, (currentLocation.location?.coordinate.longitude)!)
        let northEast = CLLocationCoordinate2DMake(center.latitude + 0.001, center.longitude + 0.001)
        let southWest = CLLocationCoordinate2DMake(center.latitude - 0.001, center.longitude - 0.001)
        let viewport = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
        let config = GMSPlacePickerConfig(viewport: viewport)
        placePicker = GMSPlacePicker(config: config)
        
        placePicker?.pickPlaceWithCallback({ (place: GMSPlace?, error: NSError?) -> Void in
            if let error = error {
                print("Pick Place error: \(error.localizedDescription)")
                return
            }
            
            if let place = place {
               print("Place name: \(place.name)")
                print("Address: \(place.formattedAddress)")
                
            } else {
               print("Place name: nil")
                print("Address: nil")
            }
        })
    }        
}
