Why do dry apricot placed in salt solution do not swell while they do so when kept in water?

The movement of water occurs from the region of high water concentration to a region of low water concentration through osmosis. When dry apricot is placed in salt solution, it will not swell up because the concentration of external solution is high (hypertonic solution) while when it is placed in water (hypotonic solution), it will swell up because water enter into the cell through endosmosis.
