[Swift-user] returning an array from function

[Agarwal, Khushbu]

Hi, 

I am a beginner with swift and I am trying to write a workflow. My workflow has 2 app procedures. The first one calls a shell script which generates X number of files which act as input into the next app procedure. My question is , how do I specify that procedure returns an array of files?  

Currently, I am seeing that the files generated from first app, get deleted... I am guessing because I am not specifying them as output files etc?

Thanks,
