No console log after updating to iOS 8.3

Hi, after updating my Xcode to latest version (6.3.2), when running app, I've been getting this message:

[INFO] :   Processing JavaScript files
[INFO] :   Processing Titanium namespace resources
[INFO] :   Compiling localization files
[INFO] :   Checking for Splash Screen localization
[INFO] :   Skipping xcodebuild
[INFO] :   Finished building the application in 8s 37ms
[INFO] :   Launching iOS Simulator
[INFO] :   Project built successfully in 3m 42s 317ms

The simulator is open but the app is not automatically run, so I can't get any console log in titanium. I can get it if I delete the app from simulator and install again but if the app is already in simulator and I run again, the same message as above appears and I don't get console log.

How can I fix this?

My studio version is 3.4.1.201410281727.
