How to list LLDB variables in Xcode?

Question

I want to list the lldb variables in Xcode debugger such as

$0 = ...

$1 = ...

Which command should i enter?

For example

Answer 1

You can use frameVariable to get a list of all variables in the stack frame.

- (void)viewDidLoad {
    [super viewDidLoad];
    NSHashTable *hashTable = [NSHashTable weakObjectsHashTable];
    ABC *object = [[ABC alloc] init];
    [hashTable addObject:object];
    //NSLog(@"%@", [hashTable anyObject]);
    object = nil;
    int i = 0;
    int j = 1;
}

frame variable

(ViewController *) self = 0x00007fa2275047d0
(SEL) _cmd = "viewDidLoad"
(NSConcreteHashTable *) hashTable = 0x000061000013f5e0
(ABC *) object = nil
(int) i = 0
(int) j = 1

Answer 2

You want to list all the variables you have defined in or are the result of expressions you've evaluated, right?

If so, there isn't a way to do that currently. But it would be straightforward to add. Please file an enhancement request with the lldb bug reporter:

and somebody will get to it.
