[Interest] Unexpected problems with Qt 5.4.1 & upgrade to Xcode 7.1

[Nuno Santos]

After a couple of hours around this issue I have found the following:

- Everything loads after all, however it takes a LOT of time! Like 100x more
- It also happens with Qt 5.5.1
- The only change Xcode and its tools

Is there any change of the new Apple tools are making qml code run a LOT slower?

My device is an iPad 2 running iOS 9 which seems to be running smoother than iOS 8.
