Optional string in a model throws partial specializations ambiguity error

[ahmdmhd]

Defining an optional string in a model throws a Ambiguous partial specializations of 'persisted_type<std::optional<std::string>>' compilation error in Xcode. I'm defining a model as such:

struct Model: realm::object {
  realm::persisted<std::optional<std::string>> optional_string;

  using schema = realm::schema<"model",
  realm::property<"optional_string", &Model::optional_string>
  >;
};

How is it possible to define an optional string? Thank you :)

Hey @ahmdmhd,

This is a bug that will be fixed later today. I will link the PR shortly. Thanks for the catch!

@ahmdmhd This will be fixed by: #18

Note that we are now supporting cpp17, so the schema does have to be declared slightly differently:

struct Model: realm::object {
  realm::persisted<std::optional<std::string>> optional_string;

  static constexpr auto schema = realm::schema("model",
      realm::property<&Model::optional_string>("optional_string")
  );
};

Once the PR is passing on CI, I will merge it.

@ahmdmhd this should work now. Please check it out and let us know.
