(new) Compiler for (old) XCode My OS X does not allow me to update to current XCode software.

With the new XCode and iOS SDK, the sourcecode is compiled with a newer compiler which has some new syntax options which are missing on my old platform.

That's why I need your help to get the new compiler to run with my XCode if possible.? Any idea or tip?

OS X 10.6.8
XCode: 3.2.6
I tried any XCode 4 setup, but it worries about the OS X version and does not allow me to upgrade :-(

The feature of the "new" compiler: ARC
XCode 4.2 will run on Snow Leopard and it has ARC support.

Go to Apple Developer Downloads and search for XCode 4.2 for Snow Leopard, it will show up there, at least if you're a registered iOS developer.

Any newer XCode version than 4.2 is not supported by Apple on Snow Leopard, so I suspect you may have problems even if you'd manage to install it.
