Question

This question already has an answer here:
Convert an array of Ints to a comma separated string [duplicate]
(1 answer)
Closed 3 years ago.
in my app i have taken an object, lets say var selectedIds = Int. i want this selectedIds to be comma seperated. because i need to send selectedids to next screen in which api calling has parameters which is comma seperated. i should get ids like 556,573 so that i can pass into parameters of receiving controller
the viewcontroller file from which i want to send selectedIds array:
class CategoryViewController: UIViewController {

Answer 1

You can convert an array of Ints to an array of strings using
selectedIds.map(String.init)
and then convert that array of strings into a single string like this
selectedIds.map(String.init).joined(separator: ",")

Answer 2

You have to map the Int array to String array and then join the array with separator comma to get a comma separated string.
params["term_ids"] = self.selectedIds.map(String.init).joined(separator: ",")
