Open Instagram from an app with filter screen opened

The task is pretty much old and solved but I can't solve even after reading all other answers on SO. I want to generate an image and open the Instagram with my image loaded into the filter screen. No "open in" menu. I want to go straight to the Instagram app.

Here's the code:


    @objc func share() {
        let fileManager = FileManager.default
        do {
            let documentDirectory =
                try fileManager.url(
                    for: .documentDirectory, in: .userDomainMask,
                    appropriateFor: nil, create: true)
            let fileURL = documentDirectory.appendingPathComponent("challenge.igo")
            if let imageData = theImage.jpegData(compressionQuality: 0.5) {
                try imageData.write(to: fileURL)


                DLog(message: "file written to \(fileURL)")


                let dic = UIDocumentInteractionController(url: fileURL)
                dic.delegate = self
                dic.uti = "com.instagram.exclusivegram"
                let res = dic.presentPreview(animated: false)
                DLog(message: "presentPreview result \(res)")
            }
        } catch {
            DLog(message: "\(error)")
        }
    }


I also implement the protocol

UIDocumentInteractionControllerDelegate
:


extension ICShareController: UIDocumentInteractionControllerDelegate {
    func documentInteractionControllerViewControllerForPreview() -> UIViewController {
        return self
    }
}


But alas the

presentPreview
function always returns
false
and no preview is opened.

What can I do wrong?
