Remarks

Warning: When this hierarchy is the AssistiveSupport.activeHierarchy, this method has a non-trivial cost on the following platforms:
  • iOS: Moving a node has a high cost that scales with the size of the subtree being moved. Avoid calling this method frequently in performance-sensitive code.
  • macOS: Moving a node has a moderate cost. Calling this method frequently can affect performance.
Moving a node in an inactive hierarchy has no native cost.
