I would really prefer using storyboards that debugging through each line of codes. Not to mention the hierarchy of views that makes it hard to read sometimes. Autolayout is fantastic but i'm not sure about the limitation when it comes to complex UI(it's kind of vague for the term complex actually). Apple introduces a new feature on autolayout this year where you can install/ uninstall constraints depending on size classses. This is really helpful if you care about the app orientation.
