I don't want to upgrade the OS.

Sorry to bring you the bad news, but you will need to upgrade your OS.

Specifically, you will need Snow Leopard 10.6.4 or later.

If you can get a really old version of XCODE/iOS SDK, you might be able to run it on 10.5.2. But they are not longer available in Apple's WebSite.
