Dwarf apple tree questions

Sooo, I have a passion for a good apple that almost matches my passion for cannabis. I have done some research on possibly attempting a dwarf tree to keep with my weed, and I ran across a bit of a problem. I found out only certain strains are "self-fruiting" and I don't know which are. If anyone could give me any information on a good self fruiting strain it would be much appreciated, also if anyone has ever done this and has any insight it would be appreciated as well.

Lol as long as you don't go planting an apple seed, well, unless you want a 90' tree dropping things that may or may not be apples...
