The documentation says:To verify ownership of your domain, select Download to get the verification file, upload it at the URL listed below, and click Verify.../example.com/.well-known/apple-developer-domain-association.txt (I used here ../ to avoid the message from being moderate)How do you create a folder called .well-known?I got this error:You can’t use a name that begins with a dot because these names are reserved for the system. Please choose another name.

Thank fou for your answer.

You need to install an Xcode version that supports iOS 9.0 simulator, like Xcode 10.2.1 and download and install the iOS 9 simulator in preferences.

Maybe you are looking for this: Add a Custom Sign in with Apple Button https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/incorporating_sign_in_with_apple_into_other_platforms

When you make the request to ASAuthorizationAppleIDProvider, you need to setup the requestedScopes including fullName. 		 let appleIDProvider = ASAuthorizationAppleIDProvider()      let request = appleIDProvider.createRequest()      request.requestedScopes = [.fullName]

There is no option for this, the user can always chooses to hide their email address. https://developer.apple.com/documentation/authenticationservices/implementing_user_authentication_with_sign_in_with_apple If the user is signed in at the system-level with their Apple ID, the sheet appears describing the Sign in with Apple feature, followed by another sheet allowing the user to edit the information in their account.  The user can edit their first and last name, choose another email address as their contact information, and hide their email address from the app.  If the user chooses to hide their email address from the app, Apple generates a proxy email address to forward email to the user’s private email address. 

I contacted Apple Support and they gave me the solution. I leave it here in case it can help others. You should review the app agreements. You can find them on the following link: https://appstoreconnect.apple.com/agreements/ You should check if both agreements are active (green).

I tried as follow, and it works ok: import UIKit import WebKit class ViewController: UIViewController {       var wkWebView: WKWebView!     override func loadView() {       let webConfiguration = WKWebViewConfiguration()       wkWebView = WKWebView(frame: .zero, configuration: webConfiguration)       wkWebView.configuration.preferences.javaScriptEnabled = true       view = wkWebView     }         override func viewDidLoad() {       super.viewDidLoad()       startLoad()     }           private func startLoad(){       wkWebView.load(URLRequest(url: URL(string: "https://www.twitter.com")!))     } }

I have the same issue, any advance on this?

I found your post and solve the error that you get as follows: Instead of: let exp = new Date(); exp.setMinutes(exp.getMinutes() + 10); 	const claims = { 			 'iss' : iss, 			 'exp' : exp.getTime(), 			 'aud': 'appstoreconnect-v1' 	}; Try: let now = Math.round((new Date()).getTime() / 1000); // Notice the /1000 let nowPlus20 = now + 1199 // 1200 === 20 minutes; const claims = { 										"iss": iss, 										"exp": nowPlus20,	 										"aud": "appstoreconnect-v1" }; You will found a new Error due that you are not passing the requested parameters to the query, look at: https://developer.apple.com/documentation/appstoreconnectapi/download_sales_and_trends_reports I also still not solve the problem completely, here is the error that I'm already getting: https://developer.apple.com/forums/thread/655667?page=1#625376022

Finally I found the solution, what happens is that the error do not point you to the right direction. What really happens is that you are using a not allowed combination of parameters as listed in: https://developer.apple.com/documentation/appstoreconnectapi/download_sales_and_trends_reports You should use a different reportSubType: api.appstoreconnect.apple.com/v1/salesReports?filter[frequency]=DAILY&filter[reportSubType]=SUMMARY&filter[reportType]=SALES&filter[vendorNumber]=xxxxxxxx&filter[reportDate]=2020-07-01&filter[version]=10 api.appstoreconnect.apple.com/v1/salesReports?filter[frequency]=DAILY&filter[reportSubType]=SUMMARY&filter[reportType]=PREORDER&filter[vendorNumber]=xxxxxxxx&filter[reportDate]=2020-07-01&filter[version]=10

Finally I found the solution to solve the problem completely, here is how: https://developer.apple.com/forums/thread/655667?page=1#625376022
