The code is unfinished but from what I have so far I keep getting an error stating that "no operator '=' matches these operands"

do
		{
			swap = false;
			for (int c = 0; c < size - 1; c++)
			{
				if (data[c].getName() > data[c+1].getName())
				{
					temp = data[c];
				}
			}
		} while (swap = true);

#include <vector>
#include <algorithm>
#include <iostream>
#include <string>
using namespace std;

class Movie
{
private:
  string name;
  string director;
public:

  Movie(string n="Movie", string d="Director"):name(n), director(d){}

  void setName(string n)
  {
    name = n;
  }
  void setDirector(string d)
  {
    director = d;
  }
  const   string getName() const
  {
    return name;
  }
  const string getDirector() const
  {
    return director;
  }
};

ostream & operator << (ostream & os, const Movie & movie)
{
  os << movie.getName();
  return os;
}

int main()
{
  vector< Movie > mv{ Movie("Foo", "boo"), Movie("Goo"), Movie("AAA", "BBB")};

  cout << "list of movies: ";
  for ( const auto & m : mv)
    cout << m << " ";
  cout << endl;

  sort( mv.begin(), mv.end(), [](const Movie & m1, const Movie & m2) {return (m1.getName() < m2.getName());});

  cout << "sorted list of movies: ";
  for ( const auto & m : mv)
    cout << m << " ";
  cout << endl;
}
