cordova-plugin-googlemaps: conflict with OneSignal-Cordova-SDK

Just for info if anyone need, I was having the same issue even following the instructions here.

Installing "cordova-plugin-googlemaps" for ios
"framework" tag with type "podspec" is deprecated and will be removed. Please use the "podspec" tag.
cordova-plugin-googlemaps depends on GoogleMaps@~> 2.7.0, which conflicts with another plugin. GoogleMaps@~> 3.1.0 is already installed and was not overwritten.

Then I tried to run pod install --verbose and the console log:

[!] CocoaPods could not find compatible versions for pod "GoogleMaps":
  In Podfile:
    GoogleMaps (~> 3.1.0)

None of your spec sources contain a spec satisfying the dependency: `GoogleMaps (~> 3.1.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

So, following the instruction I updated with pod repo update and it worked! To ensure, I removed the plugin and added again:

Adding cordova-plugin-googlemaps to package.json

Thanks!

Since cordova-ios@4.4 or below specifies platform :ios, '8.0' in platforms/ios/Podfile, you can not use GoogleMaps@3.x Pod. Because Google drops supports.

However cordova-ios@4.4 or below versions are still active in many projects. That’s why I specified two ways.

https://github.com/mapsplugin/cordova-plugin-googlemaps/blob/a5155cd34f0ea02b2ee4d37177504a4bdb5d5cca/plugin.xml#L474-L482

 <framework src="GoogleMaps" type="podspec" spec="~> 2.7.0" />

works for cordova-ios@4.4 or below versions.

    <podspec>
      <config>
        <source url="https://github.com/CocoaPods/Specs.git"/>
      </config>
      <pods>
        <pod name="GoogleMaps" spec="~> 3.1.0"/>
      </pods>
    </podspec>

works for cordova-ios@5.x with cordova-cli@9.

cordova-plugin-googlemaps depends on GoogleMaps@~> 2.7.0, 
which conflicts with another plugin.
GoogleMaps@~> 3.1.0 is already installed and was not overwritten.

As the message, GoogleMaps@~> 3.1.0 is already.
