Error While uploading Application to iOS

Dear Developer,

We identified one or more issues with a recent delivery for your app, “xxxxxx” (xxxxx). Please correct the following issues, then upload again.

ITMS-90338: Non-public API usage - The app references non-public selectors in thunkablecompanion: callWithArguments:, createRequest, determineAppInstallationAttributionWithCompletionHandler:, estimatedProgress, frameInfo, identityToken, initWithFrame:configuration:, isMainFrame, isPassthrough, lookupAdConversionDetails:, navigationType, newSocketQueueForConnectionFromAddress:onSocket:, onSuccess:, removeValuesForKeys:completion:, setNavigationDelegate:, setProcessPool:, setRequestedOperation:, setRequestedScopes:, socket:didAcceptNewSocket:, socket:didConnectToHost:port:, socket:didConnectToUrl:, socket:didReadData:withTag:, socket:didReadPartialDataOfLength:tag:, socket:didReceiveTrust:completionHandler:, socket:didWriteDataWithTag:, socket:didWritePartialDataOfLength:tag:, socket:shouldTimeoutReadWithTag:elapsed:bytesDone:, socket:shouldTimeoutWriteWithTag:elapsed:bytesDone:, socketDidCloseReadStream:, socketDidDisconnect:withError:, socketDidSecure:, toDouble, toString, userContentController, viewManager, websiteDataStore. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed.

I’m not sure where this error is coming from. I saw a couple other people report that and then the issue went away as of yesterday. Circling back here, have you had a chance to try to reupload your project and are you still experiencing this issue?
