I found a problem when the stackView contains UIlabel with AdjustsFontSizeToFitWidth=true

[softlion]

If the stack view contains a UILabel with AdjustsFontSizeToFitWidth=true and MinimumScaleFactor=.5, and the text of the label is larger than the display area, it is scaled by iOS in both directions. But the StackView does not refresh the new height of the label (as it has been scaled in both axis) and so does not place it correctly.

Does this also happen with UIStackView? Will investigate during the week, thanks for the report

The problem is more with uilabel multi line inside a table cell, I suppose your code does work.
