Both diffraction and interference occur in the double slit experiment. The wavefront is diffracted as it passes through each of the slits. The diffraction causes the wavefronts to spread out as if they were coming from light sources located at the slits. These two wavefronts overlap, and interference occurs. This is what give the diffraction pattern.
I think what you are confused about is the single slit experiment. In the single slit experiment, light passes through a single slit which produces an interference pattern. This not do to diffraction of the light. In the single slit experiment, the slit is large enough that diffraction does not occur. Instead every point along the width of the slit acts like it's own point light source, which all interfere with one another. In fact, if you make the slit narrow enough in the single slit experiment, diffraction occurs and the interference pattern goes away.
