The UIStackView property isLayoutMarginsRelativeArrangement allows insets similar to margin constraints on subviews in a UIView.
Let’s consider a simple single-subview example:
let containedView = UIView()
containedView.backgroundColor = .purple
let stackView = UIStackView()
stackView.addArrangedSubview(containedView)
You can then configure directionalLayoutMargins and enable them like so:
stackView.directionalLayoutMargins = NSDirectionalEdgeInsets(
top: 8,
leading: 8,
bottom: 8,
trailing: 8
)
stackView.isLayoutMarginsRelativeArrangement = true
This is what it looks like, before and after:
