I'm using the following code, to detect auth provider and log out properly
static func logOut() {
let auth = FIRAuth.auth()!
let provider = auth.currentUser?.providerID
switch provider! {
case "Facebook": FBSDKLoginManager().logOut()
case "Google": GIDSignIn.sharedInstance().signOut()
case "Twitter": Twitter.sharedInstance().sessionStore.logOutUserID(TWTRAPIClient.withCurrentUser().userID!)
default:
print("Unknown provider ID: \(provider!)")
return
}
try! auth.signOut()
}
But the provider is always "Firebase". What am I doing wrong? 0_o Once that code throw "Facebook" when I was logged in twitter. Thanks in advance
UPD: Yeah, I actually can store auth provider in UserDefaults
, but maybe it's Firebase bug. I'm using Firebase SDK 3.5.2
Since a user can sign into their Firebase Authentication account with multiple providers, the top-level provider ID will now (usually) be Firebase
.
But the currentUser
has a providerData
property that provides information on the speciic providers. Looping over FIRAuth.auth()!.currentUser.providerData
will give you the FIRUserInfo.providerID
you're looking for.
