    Visual instructions how to enable Google Maps on IOS using react-native-maps

UPDATE: Following instructions are now a year old. I have recently managed to upgrade react-native-maps from 0.17 to the latest version 0.21 with react-native 0.51 - if you want to follow my instruction scroll down to the end this doc! Hope that will work for you too!

This is for my personal use, things might not be correctly explained here. For the official docs please check https://github.com/airbnb/react-native-maps
Steps from scratch:
1.react-native init GoogleMapPlayground
2. cd GoogleMapPlayground
3.npm install react-native-maps --save
4.Replace in package.json following:
"react-native-maps": "^0.12.4"

into:
"react-native-maps": ">=0.12.4"

5.Run npm update
6.react-native link
7.Create the Podfile file at ios/Podfile
(but before that you might also need to add cocoapods: gem install cocoapods, if you have permission issue add sudo)
touch ios/Podfile

8.Output of the Podfile file (important: for newest version of RN scroll down to the comments - there are few examples of updated Podfile )
# You Podfile should look similar to this file. React Native currently does not support use_frameworks!
source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '8.0'

target 'GoogleMapPlayground' do
  pod 'React', path: '../node_modules/react-native', :subspecs => [
    'Core',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket'
  ]

  pod 'GoogleMaps'  # <~~ remove this line if you do not want to support GoogleMaps on iOS

# when not using frameworks  we can do this instead of including the source files in our project (1/4):
#  pod 'react-native-maps', path: '../../'
#  pod 'react-native-google-maps', path: '../../'  # <~~ if you need GoogleMaps support on iOS
end

Replace the GoogleMapPlayground with your project name (this file is a copy version from official docs https://github.com/airbnb/react-native-maps/blob/master/example/ios/Podfile)
9.Navigate to cd ios and run pod install
10.cd ..
11.open ios/GoogleMapPlayground.xcworkspace
12.Project structure in xCode (picture 1)
13.Open your project (e.g from terminal: open .)
14.Drag this folder node_modules/react-native-maps/ios/AirGoogleMaps/ into your project, and choose Create groups in the popup window. (picture 2)
15.Your project structure should look like in (picture 3)
16.Enable your Google API Key - follow this link (READ SECTION AT THE BOTTOM - IMPORTANT):
https://developers.google.com/maps/documentation/android-api/signup#release-cert

press Get Key
Create a new project or use an existing one (I used existing one for simplicity)

16.In ios/GoogleMapPlayground/AppDelegate.m add two lines of code:


before the @implementation AppDelegate

add @import GoogleMaps;


inside the (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions.....

add [GMSServices provideAPIKey:@"YOUR_GOOGLE_MAP_API_KEY"];


This is the example of AppDelegate.m

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
@import GoogleMaps;

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;
  [GMSServices provideAPIKey:@"YOUR_GOOGLE_MAP_API_KEY"];
  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"GoogleMapPlayground"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

@end

17.Go back to xCode, click on the project name, then click on Build Settings (picture 4)
18.Scroll down to section Search Paths


double click on Header Search Path  - url on the right (picture 5)


press the small plus icon in the left corner


add $(SRCROOT)/../node_modules/react-native-maps/ios/AirMaps and change from non-recursive to recursive (picture 6)


19.You are all set now!
20.Go back to your code and add some initial map, for example (index.ios.js):
/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Dimensions,
  Text,
  View
} from 'react-native';

import MapView, { PROVIDER_GOOGLE } from 'react-native-maps';

const { width, height } = Dimensions.get('window');

const ASPECT_RATIO = width / height;
const LATITUDE = 37.78825;
const LONGITUDE = -122.4324;
const LATITUDE_DELTA = 0.0922;
const LONGITUDE_DELTA = LATITUDE_DELTA * ASPECT_RATIO;


class GoogleMapPlayground extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
    };
  }

  render() {
    return (
      <View style={{ flex: 1 }}>
        <View style={{ backgroundColor: 'green', height: 100, justifyContent: 'center', alignItems: 'center'}}>
          <Text>Some div</Text>
        </View>
        <View style={styles.container}>
          <MapView
            provider={PROVIDER_GOOGLE}
            style={styles.map}
            initialRegion={{
              latitude: LATITUDE,
              longitude: LONGITUDE,
              latitudeDelta: LATITUDE_DELTA,
              longitudeDelta: LONGITUDE_DELTA,
            }}
          />
        </View>
      </View>
    );
  }
}

GoogleMapPlayground.propTypes = {
  provider: MapView.ProviderPropType,
};

const styles = StyleSheet.create({
  container: {
    ...StyleSheet.absoluteFillObject,
    top: 100,
    justifyContent: 'flex-end',
    alignItems: 'center'
  },
  map: {
     ...StyleSheet.absoluteFillObject,
  },
});

AppRegistry.registerComponent('GoogleMapPlayground', () => GoogleMapPlayground);
21.Run react-native run-ios
IMPORTANT!

Enabling API_KEY by following the link provided on point 16 - didn't work for me.
After successful build I had empty map (picture 8)
Follow these steps to enable the API_KEY:

open this link: https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend
create or use your existing project (I used existing project)
Go to credentials
Add credentials to your project - pick Google Maps Android API (picture 9)
Click on What credentials do I need
I created new API key by following the link create new api... (picture 10)
On the next screen (I chose - IOS apps) (picture 11) - Create (COPY YOUR NEW API KEY)
Navigate to Library - on your left
Click on Google Maps SDK for IOS (picture 12)
Enable it (picture 13)

22.Replace new key with the old one if you were unsuccessful previously.
23.Run react-native run-ios again and hopefully you will see the map (picture 14)
UPGRADE existing react-native-maps from 0.17 to 0.21 with react-native 0.51.0 (xCode 9.4.1)


Update Podfile according to the official docs (https://github.com/react-community/react-native-maps/blob/master/docs/installation.md#on-ios)

source 'https://github.com/CocoaPods/Specs.git'

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'NAME_OF_YOUR_PROJECT' do
  rn_path = '../node_modules/react-native'
  rn_maps_path = '../node_modules/react-native-maps'

  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
  pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"
  pod 'React', path: rn_path, subspecs: [
    'Core',
    'CxxBridge',
    'DevSupport',
    'RCTActionSheet',
    'RCTAnimation',

  ]

  # React Native third party dependencies podspecs
  pod 'DoubleConversion', :podspec => "#{rn_path}/third-party-podspecs/DoubleConversion.podspec"
  # pod 'glog', :podspec => "#{rn_path}/third-party-podspecs/glog.podspec"
  # If you are using React Native <0.54, you will get the following error:
  # "The name of the given podspec `GLog` doesn't match the expected one `glog`"
  # Use the following line instead:
  pod 'GLog', :podspec => "#{rn_path}/third-party-podspecs/GLog.podspec"
  pod 'Folly', :podspec => "#{rn_path}/third-party-podspecs/Folly.podspec"

  # react-native-maps dependencies
  pod 'react-native-maps', path: rn_maps_path
  pod 'react-native-google-maps', path: rn_maps_path  # Remove this line if you don't want to support GoogleMaps on iOS
  pod 'GoogleMaps'  # Remove this line if you don't want to support GoogleMaps on iOS
  pod 'Google-Maps-iOS-Utils' # Remove this line if you don't want to support GoogleMaps on iOS
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'react-native-google-maps'
      target.build_configurations.each do |config|
        config.build_settings['CLANG_ENABLE_MODULES'] = 'No'
      end
    end
    if target.name == "React"
      target.remove_from_project
    end
  end
end


Update ios/YOUR_PROJECT_NAME/AppDelegate.m literally exactly what the docs says
Update dependencies android/app/build.grade :

    compile project(':react-native-navigation')
    ... some other libraries...
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules

    implementation(project(':react-native-maps')){
        exclude group: 'com.google.android.gms', module: 'play-services-base'
        exclude group: 'com.google.android.gms', module: 'play-services-maps'
    }
    implementation 'com.google.android.gms:play-services-base:10.0.1'
    implementation 'com.google.android.gms:play-services-maps:10.0.1'
}


Update android/settings.gradle

The only difference from previous version was to add lib
include ':react-native-maps'
project(':react-native-maps').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-maps/lib/android')


Check if you still have your API_KEY in android/app/src/main/AndroidManifest.xml


Check if have new MapsPackage() in MainApplication.java


Previously I used react-native link react-native-maps to build my 0.17 version so I had to remove AIRMaps.xcodeproj from Libraries and remove link from Build Phase libAIRMaps.a


open ios/NAMEOFPROJECT.xcodeproj and at the top in left sidebar under Libraries delete AIRMaps.xcodeproj - should be listed there, I also deleted the red highlighted AIRMaps.xcodeproj which was listed at the very end.


in Build Phases -> Link Binary With Libraries delete libAIRMaps.a if it exists


npm uninstall react-native-maps --save
npm install react-native-maps --save
Remove again everything: rm-rf node_modules, rm-rf ios/build, rm ios/Podfile.lock, rm -rf ios/Pods, rm yarn.lock
yarn install I have yarn version 1.7
cd ios pod install sometimes I also run  pod cache clean --all and then pod repo update && pod install but it might not be necessary
cd .. watchman watch-del-all
This step is probably redundant but I might just say it anyway. So I had previously an error Print: Entry, ":CFBundleIdentifier", Does Not Exist

I opened open ios/myproj.xcodeproj - File - Project Settings - Advanced - I clicked on Custom and removed build from the path - resulting: Products: Build/Products, the same at Intermediates - Build/Intermediates.noindex
The same I did for open ios/myproj.xcworkspace
Clean the project - Product at the top - Clean


react-native run-ios I finally got Build Succeeded but I still had termination error Print: Entry, ":CFBundleIdentifier", Does Not Exist


So my final changed was: go again to myproj.xcodeproj - File - Project Settings - Advanced and instead of Custom, I picked Unique
The same for myproj.xcworkspace - File - Workspace Settings - Advanced - picked Unique


Clean the project - Product at the top - Clean for both - xcworkspace and xcodeproj
Also I double checked my Info.plist which is:
	<string>org.reactjs.native.example.$(PRODUCT_NAME:rfc1034identifier)</string>


Run react-native run-ios Success!
