Xcode not stopping on breakpoint

Question

I have some weird problem with Xcode since I upgraded my Xcode to 5 from 4.6. When I set the breakpoint in a file, the program actually stops at the breakpoint, but I can't see my code in the workspace. It loads some other system codes like

 0x2ff8:  calll  0x2ffd  -[ViewController viewDidLoad] + 13 at ViewController.m:28
0x2ffd:  popl   %eax
0x2ffe:  movl   12(%ebp), %ecx
0x3001:  movl   8(%ebp), %edx
0x3004:  movl   %edx, -12(%ebp)
0x3007:  movl   %ecx, -16(%ebp)
0x300a:  movl   18799(%eax), %ecx
0x3010:  movl   18559(%eax), %edx

enter image description here

When I click the continue button it shows my code again. I have tried,

Creating a new project
Relaunching Xcode
Restarting the system
Re-installing Xcode

None of these helped me. I have seen a lot of questions in StackOverflow which discuss "Breakpoints not working...", but for me the breakpoints are working, just not stopping in the correct position.

Are you sure it's just not crashing before it reaches your breakpoint? — Popeye, Sep 17 '13 at 11:39
It's not crashing(neither xcode nor my app), but I can see something in the workspace which will be shown when an app crashed. And when I hit continue it just runs fine. — Ramaraj T, Sep 17 '13 at 11:46
(But, on second glance, it looks like the debugger can't find your source. Did you use an "odd" build process? Have you tried to "clean" your build?) — Hot Licks, Sep 17 '13 at 12:02

I found the problem, Somehow the "Show Disassembly when debugging" was enabled in my Xcode which creates that problem. When I disabled it, all my debugger stopped in my source code.

You can find it under Product->Debug Workflow->Show Disassembly when debugging

Edit

In the latest Xcode it is under Debug->Debug Workflow->Show Disassembly when debugging

Shouldn't it be `Debug->Debug Workflow->Show Disassembly when debugging`? I found it under Debug instead of Product (great find nevertheless!). – Gerald Eersteling Aug 13 '14 at 12:35

Xcode 6:

Go to Build Settings and make sure your "Strip style" is set up as "Non-Global Symbols" and not as "All Symbols"
