I have discovered this amazing REST database service. It is called Backendless (link text). It is very fast and reliable and the trial is free. I have build a small project to test and it is working flawlessly. The full REST documentation can be found here
I am not associated with Backendless, I am just posting it here so others avoid the same mistakes I did by trying to build a Web service tied into a database. It took me a lot of time to build where instead I could’ve dedicated that time to work on the actual iOS app with Xojo.
Forgive me if this is not the appropriate place to put this.
