Pic. 1
Pic. 2
Pic.1 - it is a structure of my ViewController. Label1 and Label2 have changing size (content comes from backend) for different users. If content of labels is small, I need to set Top Space constraint for TableView (vertical spacing) to Button (pic.1), but if content of labels is big, set Top Space constraint for TableView (vertical spacing) to Stack (pic.2). How to set constraints for TableView?
Embed your image,button two labels and stack in a view.
Then add following constraints
Top, leading and trailing to new container view
vertical space b/w container and table.
Required constraints for your image,button two labels and stack
Don't add bottom constraint for button.
Add bottom spacing to stack to its superview(embedded container) with a >=.
Height to container view with minimum height and set priority to low(250)

I have a Vertical Stack View on my screen (Alignment = Fill, Distribution = Fill).
In it there are from top to bottom:
Label (no constraints)
Vertical Stack View (height=21)
Horizontal Slider (height=21)
Label (no constraints)
I was expecting that both my labels (elements 1 &4) will be of equal size and will occupy the majority of the screen and 2nd & 4th elements therefore would be in the center of the screen. But in reality my bottom Label's height is sufficient only to fill it's text while my top Label takes the majority of the space.
I tried to change the Distribution of my Stack View to Fill Proportionally, but in that case my top label becomes smaller than the bottom one.
Why is it happening? How can I make my Labels to become of equal height?
PS I noticed a warning about Content Priority Ambiguity but I can't figure out what should I do about it
To make both labels equal in height I had to select both of them and add a constraint Equal Heights.
Warning about Content Priority Ambiguity was not about them, it was about horizontal labels. To remove warning while keeping their placement I changed Distribution of the horizontal Stack View to Equal Centering.
I have a view controller with six buttons.
I want to show them in 3 rows and 2 columns.
I decided to put each column of buttons (3 buttons) in a stack view and put 2 vertical stack views in 1 horizontal stack view.
I want my buttons to look square shaped.
I applied following constraints for the horizontal (main) stack view:
Align Center X to Safe Area
Align Center Y to Safe Area
Align leading to Safe Area Equals:50
Aspect Width:Aspect Height = 2:3
For some reason aspect ratio is not working and the width is still
larger than the height and more importantly the buttons are not square shaped.
I tried to update frames, to apply all possible alignment and distribution properties, however, it didn't solve the problem. Please check images below for your reference.

Thanks in advance!
I am designing a chat app in which I am using the UITableViewAutomaticDimension property of table view when I am setting the label lines to 6 then all cells height is according to the text which label contains but when I increase the number of lines for label then some cells have extra height. Even when scrolling it then cell height again changed.You can check the image so that you can understand it easily thanks.
You need to give label constraints from top and bottom, rather than center vertically.
Give vertical content hugging priority
I have two StackView, one of which is horizontal and another vertical.
For the horizontal StackView, I want the items to be aligned to the left and grow toward the right.
For the vertical StackView, I want the items to be aligned to the top and grow downward. For example the position of the top item would never change but the stackview expands down if another item is added.
I'm having trouble accomplishing this, for example with my horizontal StackView, if I have two items 40x40, they will example the entire width of screen for some reason and I've tried a whole slew of different variations of distribution, alignment and constraints.
For my vertical StackView, if I add two items, my first item will move up and the second item will go underneath, so the center is now between the two instead of the first item staying still and the second going underneath it.
I can't figure out what I'm doing wrong here and how to just get StackViews where the first item is sized correctly, in place, and future items follow it, expanding either rightwards or downwards.
What you need is for Vertical
1- Drag a UIStackView with top , leading and trailing constraints to the superView
2- Drag any view inside it and give it a height constraint
for Horizontal
1- Drag a UIStackView with top , leading and height constraints to the superView
2- Drag any view inside it and give it a width constraint
Note : Make distribution set to fill
I have 4 labels on my storyboard, aligned at baseline and with fixed distance between them.
Each label can have different values at runtime, and I would like that the group of these 4 labels is horizontally centered.
Didn't succeed to fix it !
I tried to put them in a view and center the view, but it doesn't work either.
Tried also to play with priorities, but didn't't succeed either...
Is it possible to achieve that in the storyboard ?
You can do this by putting your 4 labels inside of another view. Add the following constraints:
Set fixed distance constraints between the labels (3 constraints).
Set constraints to align the baselines of the labels (3 constraints).
Set a leading constraint from the leftmost label to the containing view. Set the constant to 0.
Set a trailing constraint from the rightmost label to the containing view. Set the constant to 0.
Set a constraint for the height of the view.
Set a constraint from the top of the left label to the top of its containing view.
Set a constraint to center the view horizontally.
Set a constraint to position the view vertically.
The width of the view will be determined by the intrinsic sizes of the labels plus the sizes of the distances in #1. This width will change as the contents of the labels changes, and the view will keep the group centered.
You can use a Stack View for this:
In the 'Attribute Inspector' you can set for example that each text field has an equal width and a spacing of 5 points between them:
You can then use your Stack View to center horizontally like your normally would do.
