Xcode 4.4 error - Timed out waiting for app to launch
I have been programming an app and testing on simulator for a while. But recently I tried to test it on my iOS device (iPhone 4, 5.1.1)
To make it run without a developer's account, I had to edit the SDK properly list (changed code signing require to NO, and entitlement required to NO) Then i changed the Code Signing Identity to "Don't Code Sign". All was good till here.
When I tried to run it on the iOS device, I saw my app icon on my iPhone, but an error occurred on XCode saying, "timed out waiting for app to launch" and I noticed an animation as the application is being popping up but actually nothing opens up.
To see if theres anything wrong with my code/project, I created a new project and tried to run that on iOS device, I saw a new app's icon with the same problem.
Everything works perfect on Simulator.
Can anybody tell me what is this issue? And how can I fix it?
P.S. I tried restarting my iPhone and XCode. But same result. And it's on debug configuration already.
