Seems like you're talking about autocompletion, not autocorrect. In autocorrect you have completed the word, hit space and then the software fixes your typos. In autocomplete you get a list of suggested words while typing and you can tap them if your intended word is shown.
No - while auto completion is also broken, I’m talking about autocorrect. It’s a very common occurrence in Turkish iOS that something that you typed in correctly gets autocorrected to something else that makes no sense.
