Instance Method

removeAll(keepingCapacity:)

Removes all key-value pairs from the dictionary.

Declaration

mutating func removeAll(keepingCapacity keepCapacity: Bool = false)

Parameters

keepCapacity: Whether the dictionary should keep its underlying buffer. If you pass true, the operation preserves the buffer capacity that the collection has, otherwise the underlying buffer is released. The default is false.

Discussion

Calling this method invalidates all indices with respect to the dictionary.

Complexity: O(n), where n is the number of key-value pairs in the dictionary.
