A Logger call with an interpolated value stops this code from compiling.

connection.stateUpdateHandler = { state in
    // Comment out this logger call (or remove the interpolated
    // "state" variable) to fix the compilation error.
    logger.debug("stateUpdateHandler: \(state, privacy: .public)")
