“Request failed with http status code 503”

I am receiving: This seems to be an issue with all users. What is happening? Seems like CloudKit is down.

What's the correct approach to handling customer requests who said they purchased a non-renewable but we failed to receive the receipt (network or other error)? Is there a way to see the full list of transactions from iTunes connect or other sources to confirm user purchases?Thanks.

In the WWDC 2018 Session 503 Creating Photo and Video Effects Using Depth, it mentions that the Jupyter Notebook used for the demos would be available, but I can't find it anywhere.In the session, it is stated:You can go to the webpage anddownload the Jupiter [sic] NotebookTrueDepth Streamer and Backdropand we hope it inspires you as astarting point to many new coolvideo effects to create in yourapplications.Can anyone inform me where the notebook may be downloaded from? It looks like an ideal way to develop CI filters...

HiI have downloaded the sample code from https://github.com/knightsc/USBApp.I'm trying to activate driver extension, but activationRequest always fail with OSSystemExtensionErrorDomain Code=8 error.------ error message------sysex didFailWithError Error Domain=OSSystemExtensionErrorDomain Code=8Invalid code signature or missing entitlements UserInfo={NSLocalizedDescription=Invalid code signature or missing entitlements}--------------------------------A related entilement request has been sent, but no response has been received.So I edit com.apple.developer.driverkit value to NO on entitlement file for compile the code.I've modifies code about driver extension identifier and device information for my device.After compile the code, driver extension and USBApp codesign with Developer Application ID.(If codesign is not done, when launching USBApp crash occurred with Signing problem.)Also i did disable SIP.What am I missing?An

Similar to what appears to have happened last year, the Sandbox verifyReceipt endpoint is returning the 21007 status code that should only be returned by the production URL and indicates that the receipt in question should instead be sent ... to the sandbox URL. Here's the documentation: Verify your receipt first with the production URL; proceed to verify with the sandbox URL if you receive a 21007 status code. Following this approach ensures that you do not have to switch between URLs while your application is tested, reviewed by App Review, or live in the App Store. We are sending a valid sandbox receipt (validated locally on device already), along with the shared secret / password parameter, and not getting any receipt info back, just this bogus status that should only be returned by the production URL. We could mitigate this by returning something like a failure status to our own client's request, but how are we supposed to test our code

I'm simply trying to use a proxy to route a http request in Swift to measure the average round trip time of a list of proxies. I've went through multiple Stack Overflow threads on this topic but they are all super old / outdated. format:host:port:username:password I also added the info.plist entry: NSAllowsArbitraryLoads -> NSExceptionDomains When I call the function below I am prompted with a menu that says Proxy authentication required. Enter the password for HTTP proxy ... in settings I closed this menu inside my app and tried the function below again and it worked without giving me the menu a second time. However even though the function works without throwing any errors, it does NOT use the proxies to route the request. Why does the request work (throws no errors) but does not use the proxies? I'm assuming it's because the password isn't entered in the settings as the alert said. My users will want to test proxy speeds for many different Hosts/Ports, it doe

FB9895426 (Apple Device MDM enrolment fails if client certificate is requested during SSL Handshake) Device enrolment fails in an MDM Server configured with client certificate authentication. Upon investigating the issue, we noticed that the device drops the SSL handshake if a client certificate is requested during the handshake. Wireshark Screenshot: From the console logs, we noticed the below error: cannot accept the authentication method NSURLAuthenticationMethodClientCertificate The TLS protocol states that If no suitable certificate is available, the client SHOULD send a certificate message containing no certificates.. Thus, we expect the MDM client to respond with a no certificate response during the SSL handshake. Someone has already raised the same question but there's no reply yet: https://developer.apple.com/forums/thread/680328 https://developer.apple.com/forums/thread/676579 Any help would be appreciated. Thanks in advance.

***What I want***:Specify server IP for NSMutableURLRequest to avoid localDNS query.***Common method***:Replace host field in URL and specify the HOST Header field for the HTTP request. request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@https://1.1.1.1/path]]; [request setValue:@www.a.com forHTTPHeaderField:@host];***Problem***:If my server serves several domains, then the server will return a default certificate for my request. SNI only works when it finds host in url.So any suggestion if I wanna achieve ***What I want*** in ***Problem*** scene.
