How to add GoogleMaps to an iOS Application?

Steps to follow

Step 1: Create a new iOS project in XCode (Single View Application)

Step 3:  Drag these two files into your project. Check the box which says "Copy Items..." and click "Finish"

Step 4: Go to "Build Phases" under targets and expand "Link Binary With Libraries"

Step 5: Click the "+" button to add the following Frameworks

• GLKit.framework
• ImageIO.framework
• libc++.dylib

• libz.dylib
• OpenGLES.framework
• QuartzCore.framework
• SystemConfiguration.framework

Step 6: Add a new file to your project folder of the type "Objective-C File" and click "Next" button

Step 7: Give any name to the file ( Ex- Test) and click "Create")

Step 8: Now, XCode will bring up a message "  Would you like to configure an Objective-C bridging header?"

Step 10: Delete the file "Test.m" which is automatically created 

Step 11: Open the xxxx-Bridging-Header.h and type #import<GoogleMaps/GoogleMaps.h>

Step 12: Please go to "Build Settings"  tab and search for other linker flags

Step 17: Here it will display a blank text box, put the "Bundle Identifier" (Ex- com.example.trymaps)

Step 18: Click "Create" and it will create an API Key

Step 19: Go to AppDelegate.swift file and under the method "didFinishLaunchingWithOptions" add the line "GMSServices.provideAPIKey("AIzaSyAeMHNmiIzWrtul1TCsssHaf4arGwVrXyw") 

Step 20: Replace the generated API Key from step 18 in the above line
