Firebase Auth Signout Error - Swift

Question

When I try to sign out the user using this method, I just get an error:

fatal error: 'try!' expression unexpectedly raised an error: Error Domain=FIRAuthErrorDomain Code=17995 "An error occurred while accessing the keychain." UserInfo={NSLocalizedDescription=An error occurred while accessing the keychain., error_name=ERROR_KEYCHAIN_ERROR, NSLocalizedFailureReason=SecItemDelete (-34018)}: file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-800.0.33.1/src/swift/stdlib/public/core/ErrorType.swift, line 146

func logout() {
    try! FIRAuth.auth()!.signOut()
}

I didn't find anything on the web addressing this error.. does anyone know what could be the problem?

Answer 1

You need to enable the Keychain Sharing entitlement.

From the Project Navigator, go to your project settings and find your target. Under the Capabilities tab, turn on Keychain Sharing.

I had the same problem trying to create a new user. I'm not sure exactly why Firebase needs this permission now, but it works.
