OverView:- Google Maps is a web mapping service developed by Google. It offer satellite imagery,street maps 360 degree panoramic views of streets, real- time traffic condition, and route planning for travelling by foot , car,cycle,or public transportation Working with maps in consists of an entire programming as there are tons of things that a developer can do with them. From just presenting a location on a map to drawing a journey’s route with intermediate positions, or even exploiting a map’s possibilities in a completely different way, dealing with all these undoubtly is a great experience that leads to amazing results. Getting Start Step 1:- Get the latest version of Xcode Step 2:- Install the SD Create a Podfile for the Google Maps SDK for iOS and use it to install the API and its dependencies: 1. If you don’t have an Xcode project yet, create one now and save it to your local machine. (If you’re new to iOS development, create a Single View Application.) 2. Create a file named Podfile in your project directory. This file defines your project’s dependencies. 3. Edit the Podfile and add your dependencies. which includes the dependencies you need for the Google Maps SDK for iOS and Places API for iOS (optional): 4. Add this pod in Podfile in your application 5. do
 pod ‘GoogleMaps’
 pod ‘GooglePlaces’
 end 6. Save the podfile 7. Open a terminal and go to the directory containing the Podfile 8. Cd 9. Run pod install command Pod install 10. Close Xcode, and then open (double-click) your project’s .xcworkspace file to launch Xcode. From this time onwards, you must use the .xcworkspace file to open the project. Step 3:- Get an API key 1. Go to the Google API Console. 2. Create or select a project. 3. Click Continue to enable the Google Maps SDK for iOS. 4. On the Credentials page, get an API key. 
 Note: If you have a key with iOS restrictions, you may use that key. You can use the same key with any of your iOS applications within the same project. 5. From the dialog displaying the API key, select Restrict key to
set an iOS restriction on the API key. 6. In the Restrictions section, select iOS apps, then enter your app’s bundle identifier. For example: com.example.hellomap. you get the bundle identifier from your project go to project then click on the project name folder then select project-> target-> general-> identity->bundle identifier -> copy your that bundle identifier then paste that identifier those restriction section 7. Click Save. Your new iOS-restricted API key appears in the list of API keys for your project. An API key is a string of characters, something like this: AIzaSyBdVl-cTICSwYKrZ95SuvNw7dbMuDt1KG0 Step 4:- Add API key in your application Add your API key to your AppDelegate.swift Import GoogleMaps Add the following to your application(_:didFinishLaunchingWithOptions:) method, replacing YOUR_API_KEY with your API key: GMSServices.provideAPIKey(“YOUR_API_KEY ”) if you are also using the Places API GMSPlacesClient.provideAPIKey(“YOUR_API_KEY ”) Step 5:- ADD Map Now, add or update a few methods inside your app’s default ViewController to create and initialize an instance of GMSMapView. import UIKIT import GoogleMaps class GoogleMapViewController: UIViewController{ override fun loadView(){ //Mark:- Create a GMSCameraPosition there tells the map to displaying the Map // coordinate set you want suppose Coordinate latitude -33.86, longitude - 151.20 at zoom level 10. let camera = GMsCameraPosition.Camera(withLatitude: -33.86, longitude: 151.20, zoom: 10.0) let mapView = GMSMapView.map(withFrame: CGRect.Zero, camera: camera) // Mark:- Create a Marker in the Centre of the map you are designing let marker = GMSMarker() marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20) marker.tittle = “Sydney” marker.snippet = “Australia” marker.map = mapView } } Step 7:- Declare the URL scheme used by API apps must declare the URL schemes that they intend to open, by specifying the schemes in the app’s Info.plist file. To declare the URL schemes used by the Google Maps SDK for iOS add the following lines to your Info.plist LSApplicationQueriesSchemes googlechromes comgooglemaps Step 8:- Run your project
