In Apple-land there's bizarre quirks that are in the swipe-typing function too. Try swiping out "white woman" or "black woman" for example and it "corrects" it to the same incorrect phrase ("whites woman" or "black roman") every time despite getting it right originally.

It's a huge shame that (in my humble opinion) peak touchscreen typing was a decade ago when I used Windows Phone 8.1. It's been a slow decline since that only became apparent in the past couple (maybe few) years to me.

It also works for words you have typed before

I mentioned in another comment that I'm using Gboard, which is Google's POS keyboard. It's not great (and I'm looking for better replacements currently), but it does learn words if you swipe them 3 or more times in a short time.

I have a unique first and last name that never pop up in dictionary words or common name lists, and Gboard swipes them for me now, because I've used them enough times in typing and fixed their attempt at autocorrecting it. Or if it mis-reads my swiped name, it's usually one of the suggested corrections across the top of the keyboard.

I really don't like Gboard, but it's been the best I've found lately, so I always install it on new phones and tablets as soon as I get them. I'm getting suggestions in another comment thread here for viable FOSS replacements, so I'll need to test those out.

That's ducking ridiculous
