Initializer

init(sharedKeySet:)

Creates a mutable dictionary which is optimized for dealing with a known set of keys.

Declaration

init(sharedKeySet keyset: Any)

Parameters

keyset

The keyset, created by the NSDictionary class method sharedKeySet(forKeys:).

Return Value

A new mutable dictionary optimized for a known set of keys.

Discussion

Keys that are not in the key set can still be set in the dictionary, but that usage is not optimal.
