Unfortunately iOS text editing is also completely worthless. It forces strange selections and inserts edited text in awkward ways.
I’m a QWERTY texter but text entry on iOS is a complete disaster that has only gotten worse over time.
My only issue is that no keyboard implementation really supports more than two languages which makes me switch back to plain qwerty with autocomplete all the time.
It's even worse on the watch somehow. I take care to hit every key exactly, the correct word is there, I hit space, boom replaced with a completely different word. On the watch it seems to replace almost every word with bullshit, not just technical terms.
Sort of related, it also doesn't let you cuss. It will insist on replacing fuck with pretty much anything else. I had to add fuck to the custom replacement dictionary so it would let me be. What language I choose to use is mine and mine alone, I don't want Nanny to clean it up.
