how to update google maps using cocoa pods.?
<p>Hi guys I am using google maps and other libraries. I install every library using cocoapods, but when I install a library and update with command <code>pod install</code>. I am getting this error:</p>

<pre><code>Analyzing dependencies
[!] Unable to satisfy the following requirements:

- `GoogleMaps` required by `Podfile`
- `GoogleMaps (= 1.13.0)` required by `Podfile.lock`

Specs satisfying the `GoogleMaps` dependency were found, but they required a higher minimum deployment target.

<p>Here is my pod file:</p>

<pre><code>source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
pod 'GoogleMaps'
pod 'AFNetworking', '~&gt; 3.0'
pod ‘Facebook-iOS-SDK’
pod 'TwitterKit'
platform :ios, '6.0'
pod 'REFrostedViewController', '~&gt; 2.4'
</code></pre>
