There has been no shortage of attempts to do so since the early years of What if we could take physical world concepts like gravity and elasticity Placing things in an upside-down 2D coordinate system is not intuitive for anyone but geometry geeks įor the rest of us, it’s not that cut and dried. IOS developers often have to jump through several conceptual hoops when laying out user interfaces. The universal laws of physics came in quite handy -Īll I had to do was pile things up, rather indiscriminately, and move on to the next task.
