使用 Apple 登录的问题 - 无法检索名称和 email

Question

I used sample code from Apple's Juice example application to implement SIWA. But it returns nil for both name and email. To delete any previously saved credentials, I used this code:

    static func deleteUserIdentifierFromKeychain() {
        do {
            try KeychainItem(service: "app.bundle.ID", account: "userIdentifier").deleteItem()
        } catch {
            print("Unable to delete userIdentifier from keychain")
        }
    }

Then ran this code to request scope with full name and email scopes:

let request = ASAuthorizationAppleIDProvider().createRequest()
        request.requestedScopes = [.fullName, .email]
        let controller = ASAuthorizationController(authorizationRequests: [request])
        controller.delegate = self
        controller.presentationContextProvider = self
        controller.performRequests()

When I read the return values from ASAuthorizationAppleIDCredential, I get nil and nil. I do get a user identifier but no name or email.

func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
        switch authorization.credential {
        case let appleIDCredential as ASAuthorizationAppleIDCredential:

            let userIdentifier = appleIDCredential.user
            let fullName = appleIDCredential.fullName
            let appleEmail = appleIDCredential.email

What am I doing wrong?

Answer 1

Go to Apple ID settings -> delete the app from list of apps using Apple ID will reset the SIWA in iOS. Thus allowing you to test in a sandbox.
