Never mind - it seems debugging from Delphi is not possible for iOS 17 devices at the moment. I confirm that apps built against iOS 17 SDK crash on start. For now, you'll need to use an older SDK (e.g. iOS 16.4 SDK), if you had imported that earlier.

What happens if you run it via the debugger?

If it's just a simple "Hello world", you will not need to modify FMX.inAppPurchase.iOS, since it won't be using it. Does this happen if you start a completely blank project, and run that?

Can you give an example of a site where it does this?

The process on Android is to: Check the checkbox for Camera permission in the Uses Permissions of the Project Options Request the permission at runtime, e.g: PermissionsService.RequestPermissions(['android.permission.CAMERA'], procedure(const APermissions: TClassicStringDynArray; const AGrantResults: TClassicPermissionStatusDynArray) begin if AGrantResults[0] = TPermissionStatus.Granted then // Permission was granted end );

The goal is to be able to encrypt some data using crypto-js (in Javascript) and decrypt the value in a back end built with Delphi, using OpenSSL (since crypto-js claims to be OpenSSL compliant). This is the Javascript code: const CryptoJS = require('crypto-js'); var IV = '583066480e215358084bc6640df95fdd'; var passphrase = 's0m3s3cr3t!'; // According to: // https://stackoverflow.com/a/75473014/3164070 // IV is ignored, so can be anything! function encrypt(text: string): string { var key = passphrase; var iv = CryptoJS.enc.Hex.parse(IV); console.log('iv: ' + iv.toString()); var encrypted = CryptoJS.AES.encrypt(text, key, { iv: iv }); return encrypted.toString(); } This is the Delphi code. Note that OpenSSL.Api_11 comes from Grijjy (as well as the SSL binaries): unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} uses System.NetEncoding, OpenSSL.Api_11; const cPassphrase = 's0m3s3cr3t!'; procedure CryptoError; var LError: TBytes; LMessage: string; begin SetLength(LError, 120); ERR_load_crypto_strings; ERR_error_string_n(ERR_get_error, @LError[0], Length(LError)); LMessage := TEncoding.UTF8.GetString(LError); // Display the message end; function DecryptAES256(const AValue: string): string; var LContext: PEVP_CIPHER_CTX; LOutputLen, LFinalLen: Integer; LBytes, LSalt, LIV, LEncryptedText, LKey, LOutput: TBytes; begin Result := ''; LBytes := TNetEncoding.Base64.DecodeStringToBytes(AValue); // crypto-js returns an OpenSSL result, i.e. "salted__" + salt + encrypted text LSalt := Copy(LBytes, 8, 8); LEncryptedText := Copy(LBytes, 16, MaxInt); SetLength(LKey, EVP_MAX_KEY_LENGTH + EVP_MAX_IV_LENGTH); // Calc key and IV from passphrase and salt if PKCS5_PBKDF2_HMAC(cPassphrase, Length(cPassphrase), @LSalt[0], Length(LSalt), 1000, EVP_sha256, Length(LKey), @LKey[0]) = 1 then begin LIV := Copy(LKey, EVP_MAX_KEY_LENGTH, EVP_MAX_IV_LENGTH); LKey := Copy(LKey, 0, EVP_MAX_KEY_LENGTH); // Create a new cipher context LContext := EVP_CIPHER_CTX_new(); if LContext <> nil then try // Initialize the decryption operation with 256 bit AES if EVP_DecryptInit_ex(LContext, EVP_aes_256_cbc, nil, @LKey[0], @LIV[0]) = 1 then begin SetLength(LOutput, Length(LEncryptedText) + EVP_MAX_BLOCK_LENGTH); // Provide the message to be decrypted, and obtain the plaintext output if EVP_DecryptUpdate(LContext, @LOutput[0], @LOutputLen, @LEncryptedText[0], Length(LEncryptedText)) = 1 then begin if EVP_DecryptFinal_ex(LContext, @LOutput[LOutputLen], @LFinalLen) = 1 then begin Inc(LOutputLen, LFinalLen); Result := TEncoding.UTF8.GetString(LOutput); end else CryptoError; end else CryptoError; end else CryptoError; finally EVP_CIPHER_CTX_free(LContext); end; end; end; procedure TForm1.Button1Click(Sender: TObject); begin // Decrypt value output by crypto-js DecryptAES256('U2FsdGVkX1812TdTm8MD2w4u2AaxUB2PdurCNOmu4bmutkR1Ul7Z1+bGXDsdlNK5'); // This is just an example value. Generate a new one from the Javascript code end; The code "fails" at the EVP_DecryptFinal_ex stage. Have I missed anything obvious? I know there's 3rd party code that will probably handle this, however it's just this function that is required (for now), so I'd prefer to avoid introducing a bunch of dependencies

Great, thanks!!

It's because changes are required to the FMX code, specifically in FMX.MediaLibrary.Android.pas. If you have a Delphi subscription, you would be able to take advantage of changes in the Yukon beta, as per this information.

Not sure how it happened, but there was an issue with the .dproj file. I've just pushed a fix for it.

If you're building for Android 64-bit, please see this link.

That it does, thanks! From other code I found. Yes, I guess that part is wrong since the output is wrong.

Should be possible using Vision and VisionKit, as indicated by this article. It's in Swift, so you'd need to know how to translate it into Delphi, but you could use these imports: https://github.com/DelphiWorlds/Kastri/blob/master/API/DW.iOSapi.Vision.pas https://github.com/DelphiWorlds/Kastri/blob/master/API/DW.iOSapi.VisionKit.pas Please take heed of the notes in this unit!

Please see: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Deploying_Your_iOS_Application_for_Submission_to_the_App_Store You can use Transporter on the Mac to deliver the .ipa file mentioned in that link. Ignore the parts about 32-bit - it no longer applies.

That would depend on what the exact wording of the NDA is. For instance does having something like this in source code: {$IF CompilerVersion > 35} Violate the NDA?

I have some code that queries mvnrepository via HTTP, specifically looking for packages for Android. It essentially boils down to this: uses System.Net.HttpClient; procedure TForm1.Button1Click(Sender: TObject); var LHTTP: THTTPClient; LResponse: IHTTPResponse; begin LHTTP := THTTPClient.Create; try LResponse := LHTTP.Get('https://mvnrepository.com/search?q=play+services+maps'); // for example // At this point, LResponse.StatusCode is 403 :-( // The same query works in regular browsers finally LHTTP.Free; end; end; Except that recently, as per the comment, it now returns a 403 result, with this content (truncated): <!DOCTYPE html><html lang="en-US"><head><title>Just a moment...</title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=Edge"><meta name="robots" content="noindex,nofollow"><meta name="viewport" content="width=device-width,initial-scale=1"><link href="/cdn-cgi/styles/challenges.css" rel="stylesheet"></head><body class="no-js"><div class="main-wrapper" role="main"><div class="main-content"><noscript><div id="challenge-error-title"><div class="h2"><span class="icon-wrapper"><div class="heading-icon warning-icon"></div></span><span id="challenge-error-text">Enable JavaScript and cookies to continue</span></div></div></noscript></div></div> ..and is followed by a bunch of cryptic JavaScript. If there was an API (such as REST), I'd use that, however there does not appear to be, and I haven't had a reply for my email to info@mvnrepository.com. Any ideas as to how I might be able to handle it?

I must be missing the part in the answer where a body is being sent in the request.

Well, that explains it - a bug in Android 😉

It can, but there are warnings against doing it. This is an interesting article on the topic. The fact that it is possible (even though ill advised) means that the code in Delphi that turns the GET into a POST on Android, is a bug. Jon R should describe why they need to subvert the warnings against doing it 🙂

A brief example of how to reproduce it would help.

At the moment, there's nothing to solve - the error does not appear to affect creating apps using the SDK.

I've decided to go down this route - it has turned out easier than I expected, especially when using ExecuteJavascript to extract the relevant parts out of the HTML

Already did

Yeah, I had considered that, but I'd prefer to avoid it.

Complete error messages may help.

Not when using classes that parse the JSON (at least, properly), since they won't include the quotes (given your example). What code are you using to parse it?
