Instance Property


The constraints used to position current layer’s sublayers.


var constraints: [CAConstraint]? { get set }


macOS apps can use this property to access their layer-based constraints. Before constraints can be applied, you must also assign a CAConstraintLayoutManager object to the layoutManager property of the layer.

iOS apps do not support layer-based constraints.
