    You can't, because Xcode doesn't render code that way. However, those vertical lines are often used to indicate which lines will be collapsed or folded, and Xcode does support code folding:

    The vertical gray bars next just to the right of the line numbers are Xcode's way of showing how code is nested. If you place the cursor over one of those bars, Xcode highlights the beginning and ending braces. Clicking on a bar will fold the corresponding block down to a single line with ... between the braces. This is similar to what the vertical indentation lines do in some other editors.
