Open source replacement of UIStackView for iOS 8 (100% layouts supported)

Deprecated. UIStackView was introduces in iOS 9, please use the native one.

  • Supports all alignments and distributions, spacing, baselineRelativeArrangement, layoutMarginsRelativeArrangement, axis
  • Unit tested, thousands of layouts covered
  • Supports animations
  • Generates exactly the same sets of constraints as UIStackView:

UIStackView (Alignment.Leading, Distribution.FillEqually)

<'UISV-alignment' ==>
<'UISV-canvas-connection' UIStackView:0x7f9cf4816930.leading == content-view-1.leading>
<'UISV-canvas-connection' H:[content-view-2]-(0)-|>
<'UISV-canvas-connection' ==>
<'UISV-canvas-connection' V:[_UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner']-(0)-|>
<'UISV-fill-equally' content-view-2.width == content-view-1.width>
<'UISV-spacing' H:[content-view-1]-(10)-[content-view-2]>
<'UISV-spanning-boundary' _UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner'.top == priority:999.5>
<'UISV-spanning-boundary' _UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner'.bottom >= content-view-1.bottom>
<'UISV-spanning-boundary' _UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner'.top == priority:999.5>
<'UISV-spanning-boundary' _UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner'.bottom >= content-view-2.bottom>
<'UISV-spanning-fit' V:[_UILayoutSpacer:0x7f9cf4849f80'UISV-alignment-spanner'(0@51)] priority:51>
<'UISV-ambiguity-suppression' V:[content-view-1(0@25)] priority:25>
<'UISV-ambiguity-suppression' V:[content-view-2(0@25)] priority:25>

Arranged (Alignment.Leading, Distribution.FillEqually)

<'ASV-alignment' ==>
<'ASV-canvas-connection' Arranged.StackView:0x7f9cf4822c90.leading == content-view-1.leading>
<'ASV-canvas-connection' H:[content-view-2]-(0)-|>
<'ASV-canvas-connection' ==>
<'ASV-canvas-connection' V:[Arranged.LayoutSpacer:0x7f9cf2c4f3f0]-(0)-|>
<'ASV-fill-equally' content-view-1.width == content-view-2.width>
<'ASV-spacing' H:[content-view-1]-(10)-[content-view-2]>
<'ASV-spanning-boundary' == priority:999.5>
<'ASV-spanning-boundary' Arranged.LayoutSpacer:0x7f9cf2c4f3f0.bottom >= content-view-1.bottom>
<'ASV-spanning-boundary' == priority:999.5>
<'ASV-spanning-boundary' Arranged.LayoutSpacer:0x7f9cf2c4f3f0.bottom >= content-view-2.bottom>
<'ASV-spanning-fit' V:[Arranged.LayoutSpacer:0x7f9cf2c4f3f0(0@51)] priority:51>
<'ASV-ambiguity-suppression' V:[content-view-1(0@25)] priority:25>
<'ASV-ambiguity-suppression' V:[content-view-2(0@25)] priority:25>


Arranged.StackView is used the same way UIStackView is:

let stackView = StackView(arrangedSubviews: [view1, view2, view3])
stackView.alignment = .leading
stackView.distribution = .fillEqually
stackView.spacing = 20
stackView.axis = .vertical
stackView.isLayoutMarginsRelativeArrangement = true

The only difference is hiding items:

UIView.animateWithDuration(0.33) {
    stackView.setArrangedView(view, hidden: true)


  • iOS 8.0, tvOS 9.0
  • Xcode 9
  • Swift 4

Getting Started

  • Get a demo project using pod try Arranged command
  • Install, import Arranged and enjoy!


  • UIStackView observes hidden property of arranged views, delays its effect if called inside animation block, and updates constraints accordingly. I believe this behavior is confusing and impractical to implement. Arranged.StackView provides a straightforward method setArrangedView(_:hidden:) which updates constraints exactly the same way as UIStackView does, but it doesn't affect hidden property.
  • Animations require you to call view.layoutIfNeeded() - just like with any regular layout
  • StackViewDistribution.FillProportionally doesn't update its constrains when intrinsicContentSize of arranged views changes due to the fact that UIStackView uses private API (_intrinsicContentSizeInvalidatedForChildView) to achieve that
  • UISV-text-width-disambiguation constraints are not implemented because they are not documented (and you probably should disambiguate text views the way that fits your app anyway)


To install Arranged add a dependency to your Podfile:

# source ''
# use_frameworks!
# platform :ios, "8.0"

pod "Arranged"

To install Arranged add a dependency to your Cartfile:

github "kean/Arranged"
