alt Hacker NewsiOS autocomplete for the longest time was just absolutely insane. It would inject the selected suggested option into the middle of a word when I was correcting a spelling error. Really made me feel like I was doing something weird but I swear I was being normal for once.
Mine 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
