StorageDelegate

open class StorageDelegate<T> : Storage, @unchecked Sendable where T : Decodable, T : Encodable, T : Sendable

A storage delegate class that delegates its operations to a storage. It can optionally cache the stored item in memory. This class is designed to be subclassed by specific storage strategies (e.g., keychain, in-memory) that conform to the Storage protocol.

Parameters

T

The type of the object being stored. Must conform to Codable to ensure that object can be easily encoded and decoded.
