    They're the only ones I have seen so far. On Facebook: https://www.facebook.com/groups/137012246341854 and https://www.facebook.com/groups/342580832556845

    I've seen similar issues reported on social media groups. I'll be testing it myself later

    Interestingly enough, that's exactly the fix that was reported here ๐Ÿ˜‰
  4. Your project appears to include a folder in its search path that contains the file Macapi.ObjectiveC.pas, which by default is in the source\rtl\osx folder in the Delphi install, but perhaps you have a copy of the file elsewhere. The fact that it reports: Undeclared identifier: 'SObjCClassRegistrationFailed' means that there's a mismatch between the Macapi.ObjectiveC.pas it finds, and the System.RTL.Consts unit, which contains the missing identifier.
  5. I have kept Kastri very much up to date, and I "officially" support the last 2 major updates, i.e. presently 10.4.x and 11.x. Rest assured that the same will apply to Delphi 12.
  6. Where did you have the idea that SharedFileName was a property of TShowShareSheetAction? This class supports sharing only images and text. If you want to share a file, you may be interested in this: https://github.com/DelphiWorlds/Kastri/tree/master/Demos/ShareItems

    iOS 17

    No official fix as yet, however I have come up with the following workaround - Note: this has had no testing beyond a blank app: 1. Copy FMX.Platform.iOS from source\fmx into your project folder. 2. In the TApplicationDelegate.applicationDidFinishLaunchingWithOptions method towards the end, make the following change (i.e. add the one line of code indicated๐Ÿ˜ž // Creating window WindowManager := PlatformCocoaTouch.WindowManager; WindowManager.Window := TFMXWindow.Create(MainScreen.bounds); WindowManager.RootViewController := TFMXViewController.Create; // *** iOS17 SDK crash issue - Add the following line: *** WindowManager.RootViewController.Super.init; WindowManager.NativeWindow.makeKeyAndVisible; Note also that this measure is needed only if you are building against the iOS 17 SDK - it is not required when building against earlier SDKs.

    The In-App purchase issue might have been occurring only on earlier betas. Chris has extreme users ๐Ÿ˜‰

    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?
  11. Dave Nottage

    iOS 17

    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?

    TWebbrowser & camera permission

    Can you give an example of a site where it does this?
  13. Dave Nottage

    TWebbrowser & camera permission

    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 );
  14. 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

    Permissions Android 13

    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.

    Kastri and Camera Erro Demo Project

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

    Decryption of values encrypted by crypto-js, using OpenSSL

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

    Use IOS built in scan text in my iOS app

    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!

    Use testflight with Delphi

    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.
  21. Dave Nottage

    Call for Delphi 12 Support in OpenSource projects.

    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?

    Querying mvnrepository

    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?
  23. I must be missing the part in the answer where a body is being sent in the request.
  24. Well, that explains it - a bug in Android ๐Ÿ˜‰
