alt Hacker NewsMine still does this, especially when it's correcting a word. It happens when your cursor is in the word.
But I'm not sure what I hate more: the one I hate the most is when it completes for you and then you get two instances of the word, no space separation or where it corrects the word you just swiped AND the word before it... and then when you press backspace it deletes both words...
Btw, I have autocorrect disabled...
iOS typing is a fucking nightmare
The absolute worst part of OS autocomplete in general is the myriad of apps which some-fn-how break typing wherever an autocompletion is available.
I have an autocompletion for "aa" and it's triggered before I press space, meaning it's impossible to type Aaron in these fields.
I can only imagine the pain of using "composed" input methods like CJK, etc where every glyph requires multiple keypresses: https://en.wikipedia.org/wiki/Input_method
