## Topics

### Constants

[`UIStackView.Distribution.fill`](/documentation/UIKit/UIStackView/Distribution-swift.enum/fill)

A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis.

[`UIStackView.Distribution.fillEqually`](/documentation/UIKit/UIStackView/Distribution-swift.enum/fillEqually)

A layout where the stack view resizes all arranged views to the same size, filling the available space along the stack view’s axis.

[`UIStackView.Distribution.fillProportionally`](/documentation/UIKit/UIStackView/Distribution-swift.enum/fillProportionally)

A layout where the stack view resizes views proportionally based on their intrinsic content size to fill the available space along the stack view’s axis.

[`UIStackView.Distribution.equalSpacing`](/documentation/UIKit/UIStackView/Distribution-swift.enum/equalSpacing)

A layout where the stack view maintains equal spacing between adjacent views while preserving their intrinsic content size.

[`UIStackView.Distribution.equalCentering`](/documentation/UIKit/UIStackView/Distribution-swift.enum/equalCentering)

A layout that attempts to position the arranged views with equal center-to-center spacing along the stack view’s axis, while maintaining the spacing property’s distance between views.
