Change info shown in variables view of Xcode debugger

Rather than see a list of my custom objects' addresses in the variable view of the Xcode debugger, can I do something to display one of their properties, or my own description for the class instead?

enter image description here

In C#/Visual Studio this can be done by overriding ToString, so I tried overriding Description but it did not work:

-(NSString *)description
{
    std::string fieldName = *(self->FieldName);
    return [NSString stringWithFormat:@"<FieldName: %@>",
        toNS(fieldName)];
}

Not 100% the same, but, have your class conform to CustomDebugStringConvertible and provide a debugDescription. Then when you see your objects in the debug area, right click on one and hit 'print description'. Or click on one and hit the 'quick look' icon below it in the debug area. You'll see the following printout in the console:

▿ my debugged object!
- title : "name1"

You can also view properties in the debug area by clicking the disclosure triangle next to each object in the list.

Usage:

struct CustomObject: CustomDebugStringConvertible {
    var title: String

    var debugDescription: String {
        return "my debugged object!"
    }
}
