How to renew the id token using auth0 in SwiftUI app - swift

Question

I'm using Auth0 for login and logout in my iOS app. after the user logs in I get an id token which I use to make the further api calls in my app. we need to keep updating the token with auth0 as mentioned in their doc
My function is as follows
struct UpdateToken {
let credentialsManager: CredentialsManager
init() {
self.credentialsManager = CredentialsManager(authentication: Auth0.authentication())
}
func updateToken() {
guard credentialsManager.canRenew() else {
// Present login screen
print("not renewing")
return
}
Auth0
.webAuth()
.scope("openid profile offline_access")
.audience("\(audience)/userinfo")
.start {
switch $0 {
case .failure(let error):
print("token update failed")
break
// Handle error
case .success(let credentials):
// Pass the credentials over to the Credentials Manager
credentialsManager.store(credentials: credentials)
UserDefaults.standard.set(credentials.idToken, forKey: "id_token")
print("token updated")
}
}
}
}
it is printing not renewing in my console. I'm not sure what I am missing here.
the login function works perfectly fine
func login() {
Auth0
.webAuth()
.start { result in
// Handle the result of the authentication
switch result {
case .failure(let error):
// If the authentication fails, print the error message
print("Failed with: \(error)")
case .success(let credentials):
// If the authentication is successful, store the credentials and user information in UserDefaults
self.userProfile = Profile.from(credentials.idToken)
self.userIsAuthenticated = "1"
print("Credentials: \(credentials)")
// Store the ID token
print("ID token: \(credentials.idToken)")
UserDefaults.standard.set(credentials.idToken, forKey: "id_token")
// Print and store the token type and access token
print("token type: \(credentials.tokenType)")
print("access token \(credentials.accessToken)")
// Extract and store the user ID, name, and email from the user profile
print("userID is \(userProfile.id)")
let fullString = userProfile.id
let parts = fullString.split(separator: "|")
let desiredPart = String(parts[1])
print(desiredPart)
UserDefaults.standard.set(desiredPart, forKey: "userId")
UserDefaults.standard.set(userProfile.name, forKey: "userName")
UserDefaults.standard.set(userProfile.email, forKey: "userEmail")
}
}
}

It sounds like canRenew() is unable to find any stored credentials - Try using credentialsManager.store on initial login similar to how you are in updateToken(). This way the credentials are stored in the keychain when a user logs in to begin with.
