RNBiometrics.createSignature method is crashing only on iPad devcies.

[bgrajesh57]

Only iPad device (iOS version 17 and above ) createSignature method is crashing.

npm version: "react-native-biometrics": "^3.0.1",

import ReactNativeBiometrics from 'react-native-biometrics'

let epochTimeSeconds = Math.round((new Date()).getTime() / 1000).toString()
let payload = epochTimeSeconds + 'some message'

const rnBiometrics = new ReactNativeBiometrics()

rnBiometrics.createSignature({
    promptMessage: 'Sign in',
    payload: payload
  })
  .then((resultObject) => {
    const { success, signature } = resultObject

    if (success) {
      console.log(signature)
      verifySignatureWithServer(signature, payload)
    }
  })

Here is the iOS Native code

RCT_EXPORT_METHOD(createSignature: (NSDictionary *)params resolver:(RCTPromiseResolveBlock)resolve rejecter:(RCTPromiseRejectBlock)reject) {
  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    NSString *promptMessage = [RCTConvert NSString:params[@"promptMessage"]];
    NSString *payload = [RCTConvert NSString:params[@"payload"]];

    NSData *biometricKeyTag = [self getBiometricKeyTag];
    NSDictionary *query = @{
                            (id)kSecClass: (id)kSecClassKey,
                            (id)kSecAttrApplicationTag: biometricKeyTag,
                            (id)kSecAttrKeyType: (id)kSecAttrKeyTypeRSA,
                            (id)kSecReturnRef: @YES,
                            (id)kSecUseOperationPrompt: promptMessage
                            };
    SecKeyRef privateKey;
    OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)query, (CFTypeRef *)&privateKey);

    if (status == errSecSuccess) {
      NSError *error;
      NSData *dataToSign = [payload dataUsingEncoding:NSUTF8StringEncoding];
      NSData *signature = CFBridgingRelease(SecKeyCreateSignature(privateKey, kSecKeyAlgorithmRSASignatureMessagePKCS1v15SHA256, (CFDataRef)dataToSign, (void *)&error));

      if (signature != nil) {
        NSString *signatureString = [signature base64EncodedStringWithOptions:0];
        NSDictionary *result = @{
          @"success": @(YES),
          @"signature": signatureString
        };
        resolve(result);
      } else if (error.code == errSecUserCanceled) {
        NSDictionary *result = @{
          @"success": @(NO),
          @"error": @"User cancellation"
        };
        resolve(result);
      } else {
        NSString *message = [NSString stringWithFormat:@"Signature error: %@", error];
        reject(@"signature_error", message, nil);
      }
    } else {
      NSString *message = [NSString stringWithFormat:@"Key not found: %@",[self keychainErrorToString:status]];
      reject(@"storage_error", message, nil);
    }
  });
}

Please assist me on this. Do we need anything specific change required on iPad devices ?

Thanks in advance.
