I've found that many other developers are experiencing the same problem. Maybe there are really few games developed with Apple's GameKit, or else the engineers wouldn't have been serious about solving this problem.

I have the same problem, how did you solve it.

any update? i found that you can use in WKURLSchemeHandler your cases. 1. add hook for webview @implementation WKWebView (Hook) + (void)load { static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{ Method origin = class_getClassMethod(self, @selector(handlesURLScheme:)); Method hook = class_getClassMethod(self, @selector(cdz_handlesURLScheme:)); method_exchangeImplementations(origin, hook); }); } + (BOOL)cdz_handlesURLScheme:(NSString *)urlScheme { if ([urlScheme isEqualToString:@"http"] || [urlScheme isEqualToString:@"https"]) { return NO; } return [self cdz_handlesURLScheme:urlScheme]; } @end 2. set url schemehandler extension WKWebViewConfiguration{ class func proxyConifg() -> WKWebViewConfiguration{ let config = WKWebViewConfiguration() let handler = HttpProxyHandler() config.setURLSchemeHandler(handler, forURLScheme: "http") config.setURLSchemeHandler(handler, forURLScheme: "https") return config } } 3. write proxy logic in your WKURLSchemeHandler func webView(_ webView: WKWebView, start urlSchemeTask: WKURLSchemeTask) { let proxy_server = "YourProxyServer" // proxy server let proxy_port = 1234 // your port let hostKey = kCFNetworkProxiesHTTPProxy as String let portKey = kCFNetworkProxiesHTTPPort as String let proxyDict:[String:Any] = [kCFNetworkProxiesHTTPEnable as String: true, hostKey:proxy_server, portKey: proxy_port] let config = URLSessionConfiguration.ephemeral config.connectionProxyDictionary = proxyDict let defaultSession = URLSession(configuration: config) dataTask = defaultSession.dataTask(with: urlSchemeTask.request, completionHandler: {[weak urlSchemeTask] (data, response, error) in /// fix crash error guard let urlSchemeTask = urlSchemeTask else { return } if let error = error { urlSchemeTask.didFailWithError(error) } else { if let response = response { urlSchemeTask.didReceive(response) } if let data = data { urlSchemeTask.didReceive(data) } urlSchemeTask.didFinish() } }) dataTask?.resume() } :)

is_in_intro_offer_period is not work anymore and the verifyReceipt endpoint is also deprecated. https://developer.apple.com/documentation/appstorereceipts/requestbody and, If you need to determine whether the current subscription is within the free trial period, you can call check if (expires_date_ms - purchase_date_ms) is less than the specified period. https://developer.apple.com/documentation/appstoreserverapi/jwstransactiondecodedpayload let purchase_date_ms = parseInt(latest_transcation.purchaseDate) let expires_date_ms = parseInt(latest_transcation.expiresDate) let duration = expires_date_ms - purchase_date_ms var isInIntroOfferPeriod = false // free period in your introoffer // for example: 3 days free trial in my yearly subscription if (duration > 0 && duration <= 3*86400000) { isInIntroOfferPeriod = true }
