AP Yi isn't really suitable for jungling with. You can do it but AP Yi relies on farming up quickly and using the early game power of his alpha strike. Late game he falls off drastically since he only has 1 nuke, and meditate can be countered by a silence/stun/fear.
He is pretty heavily shut down by magic resist, forcing him to rely soley on lichbane procs to kill anything.
All in all, AP Yi is mostly a pubstomper Yi build. Versus teams that don't understand what to do, he'll be refreshing his alpha strike after getting a kill then proceeding to chain through your team and meditate back to full hp. Versus teams that do understand what to do, he gets forced to blow meditate after alpha striking into the middle of the enemy team, and is then CC'd and killed easily.
His early game and laning are both quite strong, though. Meditate gives him a lot of staying power, and you simply cannot stop him from farming.
