I need some help and guidance for using connecting the Google Firebase Realtime Database on my Swift app. There are some documentation out in the internet although they are outdated and for storyboards. On the other hand, there are documentation’s for swift, but they are complicated. It would be helpful if someone could provide some latest information in a simple manner on how to use realtime database for my swift app. Note that I am not willing to use Cloud Firestore, only realtime database. I am working on an important project and I need a working solution as quick as possible.
