I watched Apple a design session from Apple WWDC 2018 called Designing Fluid Interfaces last week. It was a great talk that walks us through what fluidity means, why it matters, and how Apple goes about it in practice. I admire Apple’s thoughts behind design at such a granular level, and I am a big advocate of the concept of fluid interfaces. However, I found something not quite fluid.

One day I was in Google maps and listening to music on iPhone X. I switched to the music app by swiping right along the bottom edge of the screen. I paused a song, then I tried to switch back to Google maps by swiping left. But I couldn’t.
