Depends on the child, but started with Scratch with mine for the visuals. I've heard good things about Swift Playgrounds recently too but it was rougher a few years ago. One thing that I'm not doing is pushing this too heavily as there are so many other potential interests they could develop and (I believe that) the set of STEM options are wider these days -- excepting chemistry kits which all seem to have been neutered.
