In Xcode 3.0 the distinction between Run and Debug has been blurred. You can opt to launch your application under the debugger (Debug) or not (Run), but you do not need to stop and restart your application.
There is no more Standard I/O Log or Run Log, there is only the Console. Stdin to your app is now sent via the Console log while executing and to the debugger when paused.

Ils ont l'air de considérer ça comme une feature, en plus... Et comment je fais pour donner des commandes à mon programme tout en débuggant un autre thread?...
