SwiftUIFlowLayout

A Flow Layout is a container that orders its views sequentially, breaking into a new "line" according to the available width of the screen. You can compare it to a left-aligned block of text, where every word is a View. A common use for this layout is to create a tag cloud.

The end result looks like this:

in action

  • The layout algorithm behaves differently if your FlowLayout is nested in a VStack or a scrollable parent, such as ScrollView or a List. Therefore, there's the Mode enum and mode property.
