I would like to exit out the current method that I'm stepping through.
-(void)helloWorld {
NSLog(@"Hello");
// I would like to return here, so that "World" isn't printed.
NSLog(@"World");
}
I have tried the following, but without luck.
(lldb) expr return
<no result>
Is this possible with lldb?

So, if you've just taken a step in live debugging (F10 or F11), you can use the Step Backward button to quickly navigate to the previous step. This will automatically put Visual Studio in Historical debugging mode, at the line of code you've stepped back to.
There are 2 places where we can see the method return value: In the Debugger Immediate window, using the $ReturnValue keyword. To open the Immediate window while debugging, choose Debug -> Windows -> Immediate (or press keyboard shortcut: Ctrl + Alt + I). In the Debugger Autos window.
View return values for functions If the window is closed, use Debug > Windows > Autos to open the Autos window. In addition, you can enter functions in the Immediate window to view return values. (Open it using Debug > Windows > Immediate.)
If the current line contains a function call, Step Over runs the code and then suspends execution at the first line of code after the called function returns. Step Out continues running code and suspends execution when the current function returns. The debugger skips through the current function.
Unfortunately in Xcode 4.5.x there is no way to force an early return from a function. In the current lldb sources over at http://lldb.llvm.org/ there is a newly added command, thread return, which does what you want - it includes the ability to specify the return value of the function. This won't be in Xcode until the next major release, though.
