How to implement Firebase Microsoft OAuth in iOS Swift? - ios

Question

I'm fairly new to Swift and Firebase and I'm trying to get the Microsoft OAuth provider working as described here:
https://firebase.google.com/docs/auth/ios/microsoft-oauth?authuser=0
My App is stable when run, but the MSLoginTapped button does nothing and when debugging I'm only able to see that provider.getCredentialWith doesn't appear to run because I do not receive my print statement.
There seemed to be multiple errors in the documentation, so I doctored it up as best possible and submitted a request for review of the documentation.
Firebase Documentation snippet:
provider.getCredentialWithUIDelegate(nil) { credential, error in
if error != nil {
// Handle error.
}
if credential != nil {
Auth().signInAndRetrieveData(with: credential) { authResult, error in
if error != nil {
// Handle error.
}
// User is signed in.
// IdP data available in authResult.additionalUserInfo.profile.
// OAuth access token can also be retrieved:
// credential.accessToken
}
}
}
Problem 1: provider.getCredentialWithUIDelegate is not recognized.
Problem 2: Auth().signInAndRetrieveData is not recognized.

Here's what I'm working with (that's NOT working):
class LoginViewController: UIViewController {
var ref : DatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func MSLoginTapped(_ sender: UIButton) {
let provider = OAuthProvider(providerID: "microsoft.com")
provider.getCredentialWith(nil) { (credential, error) in
if error != nil {
// Handle error.
print("Failed to retreive credential.")
return
}
if credential != nil {
Auth.auth().signInAndRetrieveData(with: credential!) { authResult, error in
if error != nil {
// Handle error.
}
// User is signed in.
// IdP data available in authResult.additionalUserInfo.profile.
// OAuth access token can also be retrieved:
// credential.accessToken
}
} else {
print("Credential is nil.")
}
}
}
}

Ran into the same problem.
let provider = OAuthProvider(providerID: "microsoft.com")
provider is a local variable, getCredentialWith is async and ARC will get rid of provider. Make it global scope.
Firebase does not show up sign page for microsoft.com in Swift / iOS
