title: Cocoapods installing old version of Stripe library by default
body: <p>Currently attempting to set up Stripe in a fresh iOS app in Swift using the following guide: <a href="https://stripe.com/docs/mobile/ios" rel="nofollow">https://stripe.com/docs/mobile/ios</a>. Immediately ran into trouble with Cocoapods. The repo can be found here: <a href="https://github.com/ktransier/stripeTest/blob/master/Podfile" rel="nofollow">https://github.com/ktransier/stripeTest/blob/master/Podfile</a></p>
  
  <p>First attempted using the line:</p>
  
  <pre><code>pod 'Stripe'
  </code></pre>
  
  <p>This resulted in:</p>
  
  <pre><code>Analyzing dependencies
  Downloading dependencies
  Installing PaymentKit (1.0.2)
  Installing Stripe (1.0.2)
  Generating Pods project
  Integrating client project
  </code></pre>
  
  <p>I need version 2.2.1 (the latest version), but it is installing 1.0.2.</p>
  
  <p>Next I attempted to use the explicit version number, as copied off the Cocoapods site: </p>
  
  <pre><code>pod 'Stripe', '~&gt; 2.2'
  </code></pre>
  
  <p>Terminal output: </p>
  
  <pre><code>[!] Unable to satisfy the following requirements:
  - `Stripe (~&gt; 2.2)` required by `Podfile`
  </code></pre>
  
  <p>Here's my stack:</p>
  
  <pre><code>CocoaPods : 0.34.4
  Ruby : ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.4.1]
  RubyGems : 2.4.1
  Host : Mac OS X 10.10 (14A389)
  Xcode : 6.1 (6A1052d)
  Git : git version 1.9.3 (Apple Git-50)
  </code></pre>
  
  <p>How can I install the latest Stripe library?</p>
