ios - Create array of strings using for-in in Swift

Question

I'm learning Swift and found one wonderful tutorial where explained how to create card game. Point is that we use 14 cards with card images and image files are named card0, card1... etc.

So, we have to create array of strings with these filename. Teacher does it with hardcoding like

var cardNamesArray:[String] = ["card1","card2","card3","card4","card5","card6","card7","card8","card9","card10","card11","card12","card13"]

I want to do it with the for-in. But when I try to do like this:

for i in 0...13 {
var cardNamesArray:String = [String(format: "card%i", i)]
}

I get error in XCode on line with for.... "Expected declaration".

Could you please point me where I'm wrong or if there is another way to do it.

Answer 1

Using map() this could be written:

var cardNamesArray = (0...13).map{"card($0)"}
