struct Alignment

Swift

struct Alignment

A point in a box: one horizontal choice and one vertical one.

Two axes in a struct rather than nine cases in an enum, which is what SwiftUI settled on and for the reason that shows up immediately here: the nine named corners are combinations, and everything that consumes an alignment consumes one axis at a time. A row container justifies its main axis and aligns its cross axis, and asking a nine-case enum for that means two nine-arm switches that have to stay consistent with each other by inspection. OverlayAnchor was exactly those two switches, and is now a spelling of this.

Named corners still read best at a call site, so they stay — as static members, which pattern-match the same way in an if and compose the way an enum cannot.
