Fail to launch "Hello World" QML App on iOS simulator

I tried to create a new Qt Quick Application on QtCreator 3.0 that comes with Qt 5.2.0 RC1 on my Mac OSX Mavericks.

When I try to launch the default "Hello World" application, it compiles it successfully, it opens the simulator with iOS 7, and then crashes.

The only debug information I succeed to retrieve comes from the Simulator itself: (more in the attachment "simulator error")

QtCreator breakpoints on:
0 realizeClass(objc_class*) realizeClass(objc_class*) 0x4ab54ea
1 _class_getNonMetaClass _class_getNonMetaClass 0x4ab403a
2 lookUpImpOrForward lookUpImpOrForward 0x4ab80e9
3 _class_lookupMethodAndLoadCache3 _class_lookupMethodAndLoadCache3 0x4ab804e

The weird thing comes when I open the compiled project in Xcode and I change the deployment target to iOS 6.1 and launches it with Xcode. It works, but not if I launch it again from QtCreator.

Xcode even fails to compile the project when the target is set to 7.0 with these 4 Apple Mach-O Linker errors (see attachment "qt qml error").

Maybe I've done something wrong with my Xcode config but I really don't think so, it's almost Vanilla installation of everything.

Best regards.
