“Request failed with http status code 503”

I am building an app that uses the ResearchKit framework from GitHub. I archived and it also runs on Simulator. When I export it, I get an error that says: Code signing ResearchKit.framework failed. How should I fix this?

When app installed from app store, iOS requests apple-app-site-association file for very first time, as I know.But if the server was down at that time, iOS will fail to obtain apple-app-site-association file.My question is, when iOS will retry to download that file under that situation.I confirmed that, 1) When App Installed or 2) When device rebootiOS requests apple-app-site-association file, but I expect that more circumstances exsists.Is there anyone who knows?

I've created App Clip for my Application, but code signing fails with below error. Provisioning profile **** doesn't match the entitlements file's value for the com.apple.developer.parent-application-identifiers entitlement.**

Hi Apple Developer Support, We're currently implementing auto-renewable subscriptions in a React Native app using the react-native-iap library. The subscription purchases are working as expected in Sandbox. We receive the transaction and purchaseUpdatedListener gives us a valid-looking transactionReceipt However, when we attempt to validate this receipt with Apple's servers, the response consistently returns status code 21002, indicating that the receipt data is either malformed or missing. We’ve confirmed the receipt is well-formed, properly passed as received, and well above the minimum size expected. The shared secret is correctly configured and matches the subscription group. We're using the correct sandbox endpoint and ensuring no modification is done to the receipt before validation. Despite this, validation fails every time. We are looking for guidance or clarification on what might cause this status, especially when the receipt is coming directly from the system aft

I'm trying to troubleshoot what is going on with my app. The app works just fine when the user is logged in. It's able to post data to my REST API just fine. But when the app goes in to the background, the BGAppRefreshTask fires off just fine, but it's unable to post its data. There payload is super small a two keys and two short strings and thats it. I've tried searching on kCFStreamErrorCodeKey -2103 and ErrorDomainKey 4 but not much comes up. Here is my error with the URL string altered... Error Domain=NSURLErrorDomain Code=-1001 The request timed out.

Problem I'm having when validating auto-renewable receiptStatus code: status code 21002Apple said: The data in the receipt-data property was malformed or missing.Trying to validate receipt server side to prevent hacks. In app purchases for auto-renewable subscription. I had converted this code from Swift 1 to Swift 3 so maybe the code is old and apple changed its ways so maybe someone can help me.Every time I run the validateReceipt() function in viewDidLoad and before I show my content. The validateReceipt() is supposed to update a isValidated bool to true when correct and false to when not validated, to continue to MainController.Using the sandbox url https://sandbox.itunes.apple.com/verifyReceiptHere is the validateReceipt() functionfunc validateReceipt() { let receiptUrl = Bundle.main.appStoreReceiptURL do { let receipt: Data = try Data(contentsOf:receiptUrl!) let receiptdata: NSString = receipt.base64EncodedString(options: NSData.Base64EncodingOptions
