Umm watch docm77 video about it, have the golem go through 3 lava things then into water, and then in the water place a tnt and you will be able to get the loot.. just watch the new video from doc it'll help you out.
Iron golem spawning is completely overhauled, so is villager breeding and trading. This makes all previous iron farms useless.
