Horizontal UIStackView with two label (one multiline label, one one-line) - ios

Question

I have a horizontal UIStackView which has two UILabel in it. First UILabel is multiline (two line) and other one is one line only. They both have default content compression and resistance priorities. My problem is that even there is a gap between labels, "best" word in first text goes second line. I noticed that first label doesn't goes beyond half of total width.
What I want is that second label should always show itself and first label should size It self for remaining space. If It can't fit to one line It should be two line. However, If second label is too short and first label is a long one but both of them can fit, first label should go beyond half of the width.
P.S I need to use UIStackView in this scenario because there are other cases. I know putting two label inside UIView may solve the problem.
UIStackView:
- Distribution: Horizontal
- Alignment: Center
- Spacing: 0
UILabel:
- Number of line: 2
- Line break: Word wrap
UILabel:
- Number of line: 1
View hierarchy:
Desired Result:
OR
EDIT: I calculate the width of second label and give width constraint. I think It solved my problem, I'll test a bit.
//Give specific width to second label to make first one calculate right number of lines.
if let font = UIFont(name: "Metropolis-ExtraBold", size: 15) {
let fontAttributes = [NSAttributedString.Key.font: font]
let size = (secondLabelText as NSString).size(withAttributes: fontAttributes)
secondLabel.widthAnchor.constraint(equalToConstant: size.width).isActive = true
}

Answer 1

To try and simplify...
Forget calculating any widths... what matters is the horizontal Content Hugging and Content Compression Resistance
Leave the left (blue) label at the defaults:
Content Hugging Priority
Horizontal: 251
Content Compression Resistance Priority:
Horizontal: 750
But set the right (orange) label to:
Content Hugging Priority
Horizontal: 1000
Content Compression Resistance Priority:
Horizontal: 1000
Results:
The only other issue would be if the text in the right-side label exceeds the full width of the view -- but you haven't indicated that you might need that much text.

Answer 2

You should set different horizontal content compression resistants for each of them:
For this case, the blue one(multiline) should have something less than the orange one(Singleline).
Assistive note: Multiline: 250, Singleline: 750
Orange Settings:
Blue Settings:
Note that I have set the line limit of the orange one to 0. You can set it to anything you like. But if you like to make it selfsize to anyhight taller view should have higher vertical compression resistant than 250.

Answer 3

First embed your multiline label inside a view and constraint the label to this view (top, leading, trailing, bottom). After that add your view with your multiline label and single line label to your stackView.
Then you can use .fillProportionally for the distribution of your UIStackView and the spacing value to specify the space between your two labels.
Make also sure to use Required (1000) for your horizontal content compression resistance priority on your right number label.

With spacing between your labels:
