Remarks
Warning: When this hierarchy is the _activeHierarchy, this method has a non-trivial cost on the following platforms:
-
iOS: Clearing the hierarchy has a high cost that scales with its size. Avoid calling this method frequently in performance-sensitive code.
-
macOS: Clearing the hierarchy has a moderate cost that scales with its size. Calling this method frequently can affect performance.
Clearing an inactive hierarchy has no native cost.
