iOS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.

The syntax for the Info.plist configuration looks like this:

NSAppTransportSecurity

  NSExceptionDomains
  
    yourserver.com
    
      
      NSIncludesSubdomains
      
      
      NSExceptionAllowsInsecureHTTPLoads
      
      
      NSExceptionMinimumTLSVersion
      TLSv1.1
    
  

If your application (a third-party web browser, for instance) needs to connect to arbitrary hosts, you can configure it like this:

NSAppTransportSecurity

    
    NSAllowsArbitraryLoads
    

If you're having to do this, it's probably best to update your servers to use TLSv1.2 and SSL, if they're not already doing so. This should be considered a temporary workaround.

As of today, the prerelease documentation makes no mention of any of these configuration options in any specific way. Once it does, I'll update the answer to link to the relevant documentation.
