Long to int32 conversion issues in Xcode 5.0.2 when building plugin for Indesign CC 2014

Question

Hi, I am trying to build one of the sample plugin WriteFishPrice from the SDK on mac System
I am using Xcode 5.0.2 as per the documentation, but I am encountering the below errors during compilation.
In UnicodeSavvyString.h
template <class FwdIterator>
inline void UnicodeSavvyString::assign_impl(FwdIterator b, FwdIterator e, size_type nCodePoints, std::forward_iterator_tag)
  const difference_type nCodeValues = std::distance(b, e);
  ASSERT(nCodeValues >= 0);
// Make room for the chars
  code_value* buffer = GetBufferForWriting(nCodeValues);  // <----Implicit conversion loses integer precision long to int
// Copy them into the buffer
  std::copy(b, e, buffer);
// Ensure terminating null
  buffer[nCodeValues] = code_value();
  fUTF16BufferLength = nCodeValues;                         // <----Implicit conversion loses integer precision long to int
// Calculate how many code points we will have at the end
  if (nCodePoints == 0 && nCodeValues)
  fNumChars = CountCharsUtil(buffer, nCodeValues);          // <----Implicit conversion loses integer precision long to int
else
  ASSERT((size_type)CountCharsUtil(buffer, nCodeValues) == nCodePoints);
  fNumChars = nCodePoints;
And similar errors are coming in WideString.h.
Can some one tell me what is wrong with the new SDK? Or if I need to make some changes in these files which surely is not advisable.

Hi kapoor_aman27,
this is just a warning, because the size of the string is stored as an int32 and some function has Argument with type int32. You can change the compiler setting "Treat Warnings as Errors" to "No". Then it is only a warning and you can ignore it as long as you use string with less than 4GB.
