Keychain

SwiftKit contains tools for working with the device keychain.

  • KeychainReader is a protocol that can be implemented by services that can read from the keychain.
  • KeychainWriter is a protocol that can be implemented by services that can write to the keychain.
  • KeychainService is a protocol that implements both KeychainReader and KeychainWriter.
  • KeychainWrapper is a util class that can read from and write to the keychain.
  • StandardKeychainService implements KeychainService and uses a wrapper to read from and write to the keychain.

These tools are used in other parts of the library, e.g. to persist unique device identifiers.
