This project claims to implement “the same algorithm Apple uses to compute native layout”. For those who haven’t built apps for iOS or macOS, Apple’s Interface Builder utility lets developers specify constraints on how elements of a UI view should layout and the layout is determined while the app is running by an algorithm so that it can adjust to device rotation or device size. The most recent commit in the associated GitHub repo was made on September 1, 2016. Does anyone know why? Is anyone aware of continued work on this sort of constraint-based autolayout for the web?
