Bug: compilation fails for unsigned integer types in containers

[eserg]

Using tiny_bridge example add a function returning a container of uint8_ts (or any other uint type):

#include <string>
#include <scapix/bridge/object.h>

#include <vector>

namespace tiny {

class contact : public scapix::bridge::object<contact>
{
public:
   std::vector<std::uint8_t> testUInt8Vec() const { return {0, 1, 2}; } // ADDED

   std::string name() { return "Hello from C++"; }
};

} // namespace tiny

Compile with:

cmake -B build/xcode_mac_objc -G "Xcode" -DSCAPIX_BRIDGE=objc -DSCAPIX_PLATFORM=apple
cmake --build build/xcode_mac_objc

The build fails:

Thank you for bug report.
I have already fixes this issue and will release an updated version soon.

[Boris-Rasin]

I've released new version, please update CModule release in your project CMake file and try again.
