Often during development, you need to populate the view controller with demo data. One solution is to change the code to use dummy data. But this means you have to change the code and remember to change it back when done.
I often use a breakpoint for this.
Using the keyword
e (short for
expression) you can execute code when the debugger hits the breakpoint.
Let’s say we have a table view showing users.
With the following lldb command we can add a user object to the
users array in a breakpoint in
You can even split the creation and the appending in two debugger commands like shown in the following screenshot.
Make sure that you check the box at Automatically continue after evaluating actions. Otherwise the debugger will stop at that breakpoint and you have to continue yourself.
