Index where doesn't return Int ?

Question

Array.index(where: { $0 == ... } returns "Array<Element>.Index" instead of an Int. Is there a way to get an Int ?

Thanks.

Answer 1

I tested the following

let listOfNames = ["aa", "bb", "cc"]
let index = listOfNames.index(where: { $0 == "bb" }) ?? -1          // becasue returns optional

print(index)

I get 1

What is your issue ?
