Spacer views should no longer be necessary unless you need space between borders.

You can create a StackView with equal spacing which will dynamically adjust the space between your stack views to use up all available space without altering the size of your subviews.

Interface builder can be a bit misleading here. the value you put in for spacing is the minimum spacing required not what the actual spacing will be.

The StackView will handle your spacing, making the size of your buttons equal you can use regular constraints for.
