Firebase not worked on real devices (iOS)

Question

I install Firebase in my iOS app. Everything works fine on simulator but on real device it doesn\'t execute / return a query to my database.

I try to clean the pro

Answer 1

I found that if you logged in, and delete the application, then after you install the application again, you will still be logged in. I do not know exactly, but I assumed that Firebase somehow binds the account cache to the Bundle Identifier, not in the local storage.

So the solution is simple and it worked for me:

1. Remove the your APP from real device.
2. Go to your project in Navigation Panel.
3. In General tab change your Bundle identifier, for example: "myApp.com" to "myApplication.com" or whatever you want.
4. Build and run
5. Bingo! Now your app should interact well with Firebase again.

Update: Firebase remembers your login in the keychain

Update: Firebase remembers your data in keychain using your Bundle identifier as key
