Breakpoints are not fired
<p>I am doing one application. I am developing my application in</p>

<p>Xcode version 4.2(4c199) with iOS 5.0(9A334) and iPhone simulator(9A334).</p>

<p>I have iPhone 4 with iOS 5(9A334) device also.</p>

<p>My problem is when  I am running the application in my device, breakpoints are not fired. I was suggested to fix the build configuration to debug. But it's not useful. So please tell me how to solve this one.</p>
