Error ODBoxHandler.m of Demo project in Xcode 9

[dobiho5]

'pod install' is ok, but I got error from ODBoxHandler.m

No visible @interface for 'DBFILESUserAuthRoutes' declares the selector 'listFolder:recursive:includeMediaInfo:includeDeleted:includeHasExplicitSharedMembers:'

Clear in method and paste to code ::

parentDirectory = @"";
        DBRpcTask *task = [self.mainClient.filesRoutes listFolder:parentDirectory];
        if(parentDirectory)
          //  task = [self.mainClient.filesRoutes listFolderContinue:parentDirectory];
        
        [task setResponseBlock:^(id result, id routeError, DBRequestError *netError){
            if(routeError || netError){
