See the difference

Same question. Same AI. The only difference is whether it has Apple's actual guidelines or not.

“How should I handle navigation in my iPad app?”

Without HIG Skills
Based on common iOS patterns, you should
use a UITabBarController with bottom tabs
for your main navigation. Add 3-5 tabs for
your key sections. You can also add a
hamburger menu for additional options.
  • Applies iOS phone patterns to iPad
  • Suggests hamburger menus (Apple discourages these)
  • No mention of iPadOS-specific conventions
With HIG Skills
Per Apple's HIG for iPadOS, use a sidebar
instead of a bottom tab bar. iPadOS has more
screen space, so a sidebar gives users
persistent, scannable navigation.
Use a split view with a two- or three-column
layout. The sidebar should collapse on compact
widths and support iPad multitasking.
  • Knows iPadOS uses sidebars, not tab bars
  • References split views and multitasking
  • Cites the specific HIG topic
