UIDocumentInteractionController doesn't work with Instagram

I need to share an image file to Instagram, and according to Instagram doc: https://www.instagram.com/developer/mobile-sharing/iphone-hooks/, I can use Document Interaction to implement this, but it just doesn't work. Here is my code:

        let img = UIImage(named: "test.jpg")
        let kInstagramURL = URL(string: "instagram://")
        let kUTI = "com.instagram.exclusivegram" // testing "com.instagram.photo" too
        let instagramCaption = "TESTING"
        let kfileNameExtension = "instagram.igo" // testing "jpg"/"ig" too

        if UIApplication.shared.canOpenURL(kInstagramURL!) {
            let urls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
            if urls.count == 0 {
                print("Not found")
                return
            }
            let url = urls[0].appendingPathComponent(kfileNameExtension)
            print("URL", url)
            // OUPUT: file:///var/mobile/Containers/Data/Application/F14B18CB-5CD4-47AD-8257-E2288C23181E/Documents/instagram.igo
            do {
                try UIImageJPEGRepresentation(img!, 1.0)?.write(to: url, options: .atomic)
                print("WRITEN", url) // Written successfully, no error
            } catch {
                //TODO: issue error on UI
                print("WRITE ERROR: \(error)")
            }

            let documentInteractionController = UIDocumentInteractionController(url: url)
            var rect = CGRect.zero
            let view = self.view

            documentInteractionController.delegate = DocInteractionResponder() // tried nil, same result
            documentInteractionController.uti = kUTI


            // adding caption for the image
            documentInteractionController.annotation = ["InstagramCaption": instagramCaption]
            documentInteractionController.presentOpenInMenu(from: rect, in: view!, animated: true)
        }
        else {
            //TODO: warn from dialog
        }

I have tried many things within this code snippet (see comments), but the result is the same: after I tap instagram in the menu, nothing happens.

I thought it may be caused by other code in my app, so I create a blank app (with one simple UIViewController) and put this code in. It doesn't work.

I have read almost all answers on SO related to UIDocumentInteractionController.

Does this happen to you? Is this the problem with iOS 11 (just upgraded my phone), or maybe Instagram stop supporting Document Interaction?

I just came across the same issue today, and I was able to solve it by declaring the UIDocumentInteractionController as a class-level property in the view controller, to prevent it from getting deallocated too soon.
