"An error occurred while accessing the keychain" when signing in using Firebase

Question

Background:

I'm using Firebase for my apps login. I am using the login via email address functionality. The error started after starting to use the new xCode beta and updating the code to Swift 3

You can see a prototype of the problem here: https://bitbucket.org/gilosborne/firebasetest

The error:

When I try to log in I get the error, "An error occurred while accessing the keychain".

I am not using Apple keychain in any way, I believe it is referring to the mentions of keychain here: https://firebase.google.com/docs/auth/ios/errors

When I enter the email address wrong i get the correct error saying the email address doesn't match. And creating a new account still works also. I only get the error when login in correctly with an existing email address.

After looking into the firebase documentation above more I printed: print(error?.userInfo[NSLocalizedFailureReasonErrorKey])

and

print(error?.userInfo[NSUnderlyingErrorKey])

to try and learn more and got these console logs

Optional(SecItemAdd (-34018))

nil

I'm very new to iOS development, but I have spent hours or googling and racking my brain trying to fix this and have made zero progress.

Again, everything was working just fine. All I did was updated to Swift 3.0 and this started happening. Any help would be really awesome, thank you!

ps. Sorry if I missed anything, this is my first time posting.

Try turning on the Keychain Sharing in Capabilities of your projects' target. that worked for me. Keychain Sharing
