Debugging an app outside XCode on different version of OSX (view exceptions, logs, ...)

I'am developing on Lion 10.7 an XCode 4.2 beta. I need to test my app on Snow Leopa开发者_运维问答rd and catch crashes, NSLog etc, without XCode. In Snow Leopard the 10.7 SDK is missing, and I can't compile and use the embedded debugging suite of XCode.

What should I do?

From what I understand, I think you need to download the Xcode 4.2 beta for both Lion and Snow Leopard. These are two different versions. Get them from the Mac App Store or Apple's Developer website.

Just Discovered that Console will trace all my app NSLog / crashes.
