I created a simple application that accesses a DataSnap server.

When I run in simulator (iOS 9) or iPad 2 (iOS 9.0.1), everything works perfectly.

When I run on the iPhone 5, an error message appears when connecting to DataSnap Server (External Exception 434C4E47432B2B00).

Any idea?

  • I made a bug registry in the quality of Embarcadero site and today I received the following reply. Sergey Krasilnikov added a comment - an hour ago Hi all! Good news, this issue has been resolved for Seattle Update 1. From external Jira: This is a problem with TStringHelper.InternalCompare Next code fails with iOS9 SDK: string.Compare('short', 'loooong', True); – Zoe Tecnologia Oct 16 '15 at 12:41

You must change your datasnap server(tcp/ip) to rest server(http) And change your client plist file (Project.plist) Go to the bottom of the file and insert the following text above the last /dict tag:

            <key>NSAppTransportSecurity</key>
            <dict>
              <key>NSAllowsArbitraryLoads</key><true/>
            </dict>
