问题
I need a data from one Firebase project's database in 2 iOS apps (with different bundle names). So, the question is:
Is it possible to configure replication between 2 different Firebase project's databases? Or is it possible to use 1 Firebase project (1 database) for 2 ios apps?
回答1:
There is no built-in feature to replicate Firebase Databases.
I'm not aware of any tools that replicate between two Firebase Databases. The closest is probably making a backup from one database and restore to another, but it'll be a parent/child setup.
Yes, multiple iOS apps can talk to the same Firebase Database. Just click to add another app on your project's Firebase Console.
