You can print the stack trace in the NSLog by

NSLog(@"Stack trace : %@",[NSThread callStackSymbols]);

Upon a crash, next to the word (lldb), you can type:

po [NSThread callStackSymbols]

Edit:

For better output on console on Swift you can use following line instead:

Thread.callStackSymbols.forEach{print($0)}

You can add breakpoint before exception is thrown. First go to Breakpoint Navigator (cmd + 6). In the bottom left corner mouse click plus button. OR You can use Instruments (/Developer/Applications/Instruments) to help detect usage of zombie objects. Reference

And When you add breakpoint review the picture will create by Xcode.

You can expand the stack trace using the slider at bottom use step over and over for line by line logs.

Use the bt command in (lldb).

Once paused or after a crash, just type bt into the debug console.
It will print the full stack trace.
