Hello guys, I have an app that generates QRCodes, I want to dismiss the viewcontroller after my qrcode scanned by another device. How can I do this? Thanks.

I dont think such a thing is possible. The other device that will have to send a "notification" to you app to dismiss the view controller. I believe something like that is only possible with multipearconectivity. and that is only available when both devices use the same app due to privacy.

I believe I will be able to do it with a Firestore snapshot listener. Thanks for the reply. Hope it won't fail :)
