TagListView

TagListView is a container view which aligns its children(tags) from left to right and from top to bottom. It has the following benefits:

The alignment is done by setting children' frames and not using Auto Layout, which should theoretically give a faster layout calculation.
It adjusts its height to fit all its children automatically.
Its children can be any subclass of UIView.

Features

var alignment: Alignment { get set }

It controls how the children within a row should be placed in the main axis. Possible values are start, center and end.

var crossAxisAlignment: Alignment { get set }

It controls how the children within a row should be aligned relative to each other in the cross axis. Possible values are start, center and end.

var spacing: CGFloat { get set }

It controls how much space to place between children in a row in the main axis.

var rowSpacing: CGFloat { get set }

It controls how much space to place between the rows themselves in the cross axis.

func addTagView(_ view: UIView)
func removeTagView(_ view: UIView)

These two functions should be used to manage tags rather than addSubview and removeFromSuperview.

Remarks

For TagListView to layout properly its width must be constrainted horizontally by

Setting a width constraint equal to a constant.
Setting left and right constraints with 'equal' relation.
Setting the frame's width directly.
