Although this problem seems to persist as a bug and will likely be fixed, it stems from the new App Transport Security that has been implemented in iOS 9.

If your application pulls data from a web server, in order to populate the View Controller that you will be presenting, you can resolve these errors by verifying/granting access to the particular site(s) you're pulling from.

In order to address this you will add the following to your App's .plist file:

• You may want to alter your ATS Exception Dictionary to fit your needs

  NSAppTransportSecurity
  
      NSExceptionDomains
      
          testdomain.com
          
              NSIncludesSubdomains
              
              NSExceptionAllowsInsecureHTTPLoads
              
              NSExceptionRequiresForwardSecrecy
              
              NSExceptionMinimumTLSVersion
              TLSv1.2
              NSThirdPartyExceptionAllowsInsecureHTTPLoads
              
              NSThirdPartyExceptionRequiresForwardSecrecy
              
              NSThirdPartyExceptionMinimumTLSVersion
              TLSv1.2
              NSRequiresCertificateTransparency
              
          
      
  
  

More details to this solution can be found here or here The Apple Documentation for App Transport Security is worth reading too.
