Haha sometimes I want to type f*ck and it gets auto corrected to duck. But once I was trying to type “pura” (pure in Spanish, I do have Spanish enabled for auto correct) and it auto corrected it to “puta” (look it up). Shrug.
I'm in the same boat. This is bewildering to me, because I recall Apple making a joke about (it being fixed) in this in the 2023 developer conference:
The workaround is to add fuck as a shortcut for fuck. They intended the translation for doing things like translating omw to "On my way" but it works as a hack to let you use profanity without autocorrect killing it.
