Fringed Twinevine

I suppose it is also known as Climbing Milkweed.  The pitcure below shows the twining.

The flowers can be white or tinged with pink or purple. 

The seed definitely looks like milkweed. 

And they may taste like milkweed, too as the milkweed bugs seem to like it. 

One is hiding behind the plant.  You can see the twinevine twisting through another plant, the Desert Broom (aka Turpentine Bush)
