How to remove Optional from the view and how to "nil" does not appear?

Answer 1

If we get nil, what string should appear in the goals labels? You need to specify that. Then you can write this:
let ifnil = "" // or whatever the desired string is
cell.homeGoalLbl.text =
events[indexPath.row].result.goalsHomeTeam.flatMap {String($0)} ?? ifnil
cell.awayGoalLbl.text =
events[indexPath.row].result.goalsAwayTeam.flatMap {String($0)} ?? ifnil
That will do both jobs at once — it eliminates both "Optional" and "nil" as possible label values.
