Latch

public struct Latch

Latch is a simple abstraction around the iOS and OS X keychain API. Multiple Latch instances can use the same service, accessGroup, and accessibility attributes.

  • Create a new instance of Latch with a service, accessGroup, and accessibility.

    :param: service The keychain access service to use for records. :param: accessGroup The keychain access group to use - ignored on the iOS simulator. :param: accessibility The accessibility class to use for records.

    :returns: An instance of Latch.
