Previous Answer
You have to convert the String to Int
let stringOfints = "8,9,10"
let arrOfIds = stringOfints.components(separatedBy: ",").compactMap { Int($0) }
Updated Answer
Modify the code inside API call like below and try.
let arrOfIds = value?.components(separatedBy: ",").compactMap { Int($0) } ?? []
for singleCat in kat {
if arrOfIds.contains(singleCat.id ?? 0) {
self?.arrSubCat.append(singleCat.title ?? "")
}
}
