FireBase error with IOS device

Good afternoon!

I am currently working on the app about climate change. It has to have an option of login and singup. For username and password to be saved in the database I use the "Experimental --> FireBaseDB", however after I added it to my screen I got the error saying: "Error from Companion: error: undefined variable. (irritants: yail/" and now everytime I am editing something on the screen this error pos up. As far as I know this option doesn't work on IOS devices, and I was just wondering if there's any way I can fix it because I am working on IOS and I can't switch to Android.

Thank you!

Unfortunately, the porting over of FirebaseDB to iOS hasn't started yet.
