This property is applicable only for direct children of auto-layout frames, ignored otherwise. Determines whether a layer should stretch along the parent’s primary axis. 0 corresponds to a fixed size and 1 corresponds to stretch.
0 and 1 are currently the only supported values.
Note: If the current node is an auto-layout frame (e.g. an auto-layout frame inside a parent auto-layout frame) if you set
layoutGrow to 1 you should set the corresponding axis – either
counterAxisSizingMode – to be
“FIXED”. This is because an auto-layout frame cannot simultaneously stretch to fill its parent and shrink to hug its children.
