Value of type 'GIDSignIn' has no member 'signInSilently'

Question

What is this error, please guide no material found anywhere on google so far. Below is my code which is giving error:

if GIDSignIn.sharedInstance().hasAuthInKeychain() == false {
               GIDSignIn.sharedInstance().signIn()
           } else {
               if let user = GIDSignIn.sharedInstance().currentUser {
                   service.authorizer = user.authentication.fetcherAuthorizer()
                   fetchEvents()
               } else {
                   GIDSignIn.sharedInstance().signInSilently()
               }
           }

Two errors coming:

Value of type 'GIDSignIn' has no member 'hasAuthInKeychain'
Value of type 'GIDSignIn' has no member 'signInSilently'

Answer 1

Please check the GIDSignIn version you are using. From v5.0.0 :

signInSilently has been replaced with restorePreviousSignIn .

hasAuthInKeychain has been replaced with hasPreviousSignIn .
