Auto Layout with an Extended Visual Format Language
summary
Library banjun/NorthLayout extends Visual Format Language by letting segments wrapped in double vertical bars generate constraints to layout margins rather than superview edges, which lets margins stand in for safe area on all iOS devices. It parses extended VFL with kareman/FootlessParser into an abstract syntax tree, converts margin segments into margin constraints and emits standard Auto Layout constraints, and reduces boilerplate so existing VFL code works with minimal changes.
