    uint8_t MGCopyAnswer_arm64_impl[8] = {0x01, 0x00, 0x80, 0xd2, 0x01, 0x00, 0x00, 0x14};
      const uint8_t* MGCopyAnswer_ptr = (const uint8_t*)MSFindSymbol(NULL,"_MGCopyAnswer");
      if(MGCopyAnswer_ptr!=0){
          NSLog(@"*************************step 1");
          if (memcmp(MGCopyAnswer_ptr, MGCopyAnswer_arm64_impl, 8) == 0) {
              NSLog(@"*************************step 2");
          } else {
              NSLog(@"*************************step 3");
          }
      }
  
   i got the (TweakInject.dylib)[1494] <Notice>: Received signal 11 after step 1, does anyone know why?
