hello, eveyrone i am a newbie, just learned swift couple months ago. i just watched this video, i am not fully diguesting everything Brian said, but try the best i can to use as much code as possible. my code still have UI and storyboard, but i use the Brian's method here and i add prepareforsegue method in the viewcontroller to pass the postuid to the new viewcontroller, is there any downside of this when coding ? or as long as works is fine ? thank you in advance.
