Hi, I was wondering if i need to do a full test after updating swift syntax. I have a B2B app, against my wishes the senior programmer added swift coding. We have about 10 customers using our App. Every time the Swift Syntax Gets updated i feel the need to do a full test but time just doesn't permit me to do so because i have to fix bugs and add new features before the deadline (tradeshow dates where they would use the app) Now every time there is an iOS or Xcode update we have to update the Swift Syntax. Is it necessary for me to do a full test or should it be OK? I'm just afraid that the user won't be able to print, send orders, etc etc. But I'm thinking it SHOULD be ok. To do a full test everytime for every customer is just extremely time consuming and literally wastes days. Can i get your opinions?
