 # 11.7.0
-- [changed] Refactored the base `DataConnectError` error type to be a protocol instead of an enum and introduced concrete error types `DataConnectInitError`, `DataConnectCodecError`, `DataConnectOperationError`. Note that if you have code using a `switch` on the previous error enum, you will need to update that code. See the [PR] (https://github.com/firebase/data-connect-ios-sdk/pull/42) for a usage example and `DataConnectError.swift` for implementation details.
