title: Pod Spec Validation Cocoa Pod issue
body: <p>I keep getting validation errors when i run pod spec lint. I tried various versions of the pod spec file and it is still not going through. I did create a swift file to point to version 3.0 in github and all other ways to avoid the issue. This is the podspec file I have: </p>
  
  <pre><code>Pod::Spec.new do |s|
  s.name         = "SwiftImageCarousel"
  s.version      = "1.0.0"
  s.summary      = "SwiftImageCarousel is an easy-to-use carousel.”
  s.description  = "SwiftImageCarousel is an easy-to-use carousel. Just give it the image URLs, let it do the rest for you!”
  s.homepage     = “https://github.com/Centroida/SwiftImageCarousel"
  s.license      = "MIT"
  s.platform     = :ios, "10.0"
  s.source       = { :git =&gt; "https://github.com/Centroida/SwiftImageCarousel.git”, :tag =&gt; “1.0.0” }
  s.source_files = "SwiftImageCarousel", "SwiftImageCarousel/**/*.{h,m,swift,storyboard}”
  s.pod_target_xcconfig = { 'SWIFT_VERSION' =&gt; '3' }
  end
