I wanna make a Star Rating for a Job Performance Survey using UITableView and Cosmos. My Problem is, that I have absolutely no clue, how I can access and store the rating, the user is giving for each row.
Maybe someone could help me! :) This is what I have so far... I tried so many different possibilities but always failed massively. I set the initial Rating of the Items to 0, which then should get updated as soon as a user rates it and gets ultimately stored afterwards in Firebase completely when the user presses "save"

@IBOutlet weak var cosmos: CosmosView!
var id: Int = 0
func update(_ rating: Double, id: Int) {
cosmos.rating = rating
self.id = id
cosmos.didFinishTouchingCosmos = { [weak self] rating in
print(self?.id) // Access property here
}
