[clang][ExtractAPI] Add a space between type and name in property declaration fragments

[zixuw]

Awesome! Thanks Daniel!

clang/lib/ExtractAPI/DeclarationFragments.cpp

if (Attributes != ObjCPropertyAttribute::kind_noattr) {
 
     Fragments.append(")", DeclarationFragments::FragmentKind::Text);
   }
 
   // Build the property type and name, and return the completed fragments.
   return Fragments.appendSpace()
       .append(getFragmentsForType(Property->getType(),
                                   Property->getASTContext(), After))
+      .appendSpace()
       .append(Property->getName(),
               DeclarationFragments::FragmentKind::Identifier)
       .append(std::move(After));
 }
 
 DeclarationFragments DeclarationFragmentsBuilder::getFragmentsForObjCProtocol(
     const ObjCProtocolDecl *Protocol) {
   DeclarationFragments Fragments;
