"Here is a guide for the definitively best method to chain for shiny/perfect IV Dittos (so people don't have to keep posting small changes to other existing methods)"

You need to get a Garbodor (holding a Leppa berry), any Pokemon that knows false swipe, a Hypno that knows Switcheroo, and a level 1 Klefki that only knows RecycleGarbodor should be holding a Leppa berry and have the moves Recycle, Substitute, Rock Polish, and any Poison type attacking move. Hypno should also be holding a Leppa berry and have the moves Switcheroo and Thunder Wave (So you can paralyze the Ditto when you find one you wanna catch)As soon as you encounter a Ditto, send out the level one Klefki and let Ditto transform, then switch to Hypno and use Switcheroo to give it the Leppa berry. Then switch to your false swipe Pokemon and bring the Ditto to one health. So now you have a Ditto that is a Klefki with the stats of a level one Pokemon and it only knows Recycle and it has a Leppa berry. So it can never kill itself and it can never hurt you.Now switch to Garbodor and use Subtitute. This will prevent the new Dittos from transforming even if they have Imposter. Then use an Adrenaline Orb and max out your speed by using Rock Polish 3 times. You should outspeed all of the new Dittos and now you are free to chain for as long as you want since you have a Leppa berry and Recycle. And your only attacking move is Poison type so there is no chance to accidentally kill the original Ditto since it is a Klefki and Klefki is immune to Poison type movesYou can chain infinitely with this setup with no risk at all.
