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

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.
