getNext doesn't appear to be working on getMyFollowedArtists

[amiantos]

I'm trying to use if object.canMakeNextRequest to get all possible artists returned by getMyFollowedArtists however the second request doesn't appear to be returning an object with any items in it. I've tested my code with the getMyTopArtists method and it works properly. I've also manually changed the limit on getMyFollowedArtists to ensure that the API will return more than the default limit, and it does.

Here's a sample of my code just to see what I am doing.

    var artists: PagingObject<Artist>? {
        didSet {
            print("Added more to artists variable.")
        }
    }

    func grabSpotifyArtists(token: String?) {
        Spartan.authorizationToken = token
        Spartan.loggingEnabled = true

        _ = Spartan.getMyFollowedArtists(limit: 10, after: nil, success: { (object) in
            self.artists = object
            self.printArtists()
            self.fetchAllItems()
        }, failure: { (error) in
            print(error)
        })

    }

    func fetchAllItems() {
        if let artists = self.artists {
            if artists.canMakeNextRequest {
                artists.getNext(success: { (object) in
                    self.artists = object
                    self.printArtists()
                    self.fetchAllItems()
                }) { (error) in
                    print(error)
                }
            }
        }
    }

    func printArtists() {
        if let artists = self.artists?.items {
            for artist in artists {
                print(artist.name)
            }
        }
    }

Sample output:

What I'd expect to happen is the what happens if I use the getMyTopArtists method like so... changed code following way:

    func grabSpotifyArtists(token: String?) {
        Spartan.authorizationToken = token
        Spartan.loggingEnabled = true

        _ = Spartan.getMyTopArtists(limit: 10, offset: 0, timeRange: .longTerm, success: { (object) in
            self.artists = object
            self.printArtists()
            self.fetchAllItems()
        }, failure: { (error) in
            print(error)
        })

    }

Hi, I have a similar issue with the canMakeNextRequest but while searching. However the getMyFollowedArtists canMakeNextRequest does work for me.

This is a code snippet I use, just call it the first time with getFollowing(after: nil):

func getFollowing(after: String?) -> Void {

    _ = Spartan.getMyFollowedArtists(limit: 50, after: after, success: { (pagingObject) in

        /* do something with the object e.g. your code:
          self.artists = pagingObject
          self.printArtists()
          self.fetchAllItems()
         */ 

        if pagingObject.canMakeNextRequest {
            // (optional) sleep 100ms
            usleep(100000)
            self.getFollowing(after: pagingObject.cursors?.after)
        }

    }, failure: { (error) in
        print(error)
        // TODO error handling
    })
}

@tomaculum thank you! This is clearly a workaround for a faulty .getNext() method, but it works and for that I am very grateful. I'm going to keep this issue open. A million thank yous!
