Sure, you shouldn't have to, but sometimes you're developing in an environment where adding a print statement + restarting + reproducing is faster than waiting for your IDE debugger to download whatever state information it needs (or whatever it's doing) l to render a prompt. For example, Xcode takes an eon to show a lldb prompt when you hit a breakpoint. Printing is instant every time.

Further, there are cases where variables are optimized out of builds so you have to add code to ensure they stick around (in which case you may as well print). Again, this applies to iOS development. Maybe others.
