Filed under:
- (void) swapController:(MyViewController*)controller1 
                         with:(MyViewController*)controller2
{
    MyViewController *swap = controller2;
    controller2 = controller1;
    controller1 = swap;
}

Looks like this doesn't work because I'm not passing references. How to do it anyway?
