I have two UIView in StackView Horizontal. In UIView posted UILabel. I need the first one to be the priority. The main requirement is a complete lack of a fixed width in any UI. enter image description here
Set the setContentCompressionResistancePriority(_:for:) higher for the required label and lower for the other one. Example:
textLabel1.setContentCompressionResistancePriority(UILayoutPriorityDefaultHigh, forAxis: .Horizontal)
textLabel2.setContentCompressionResistancePriority(UILayoutPriorityDefaultLow, forAxis: .Horizontal)
