The app located at https://itunes.apple.com/in/app/vmware-vcloud-client-for-ipad/id499333133?mt=8 is only for VCD 1.5 and is no longer supported.

Till VMware takes it down, beware of downloading it.

 If you are looking for an alternative for Vcloud Director version 5.x, there is an android app located at that you could try.
