title: Cocoapod pod only for a specified platform
body: <p>I have an Xcode project with multiple targets. One of those targets targets the tvOS platform. My other targets make use of the 'youtube-iso-player-helper' framework, which does not support tvOS. I want to have a Cocoapod Podfile that includes the player framework only on iOS. </p>
  
  <p>Here is my current Podfile: </p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git' 
  platform :ios, '8.0'
  platform :tvos, '9.0'
  
  use_frameworks!
  
  pod 'SVGgh'
  
  pod "youtube-ios-player-helper", "~&gt; 0.1"
  
  xcodeproj 'MyProject.xcodeproj'
  </code></pre>
  
  <p>When I try to update my pods, I get the following error:</p>
  
  <blockquote>
    <p>[!] The platform of the target <code>Pods</code> (tvOS 9.0) is not compatible with <code>youtube-ios-player-helper (0.1.4)</code>, which does not support <code>tvos</code>.</p>
  </blockquote>
  
  <p>Obviously, this is using the current version of Cocoapods.</p>
  
  <p>So, I need to know the syntax required for my Podfile.</p>
