I want to get a list of followers of a user that has authorized my app via their twitter account, using the TwitterKit for iOS or their REST API. Similar to how facebook returns a user's friends that have the app installed on their facebook account.
I know this wasn't possible a couple of years ago. (15075606, 10908702)
But is this available today? Does anyone have a workaround?
Last option is to store the user's Twitter ID on a server and compare it with the ids that get returned when fetching a user's followers.
No, this is not available in the Twitter API.
