The whole selecting text with your finger thing sux in iOS as far as I'm concerned. Selecting text or positioning the insertion point (cursor if there was one) is not precise at all, especially if you have old, ft fingers! You can manipulate the selection point, but that is still very clunky. And far too often trying to position an insertion point is so clunky that you wind up selecting a word instead. Say I type the word wrong and want to correct the typo, and not all typo are automatically caught BTW, trying to select the precise position within the word is a lessen in frustration. Chances are it will just select the entire word, I get frustrated, let out a string of words that would make a sailor blush, then give up and just retype the whole word. Yes, I know there are a gillion gestures built in, but I really think that iOS should be intuitive and it should not require reading a huge document to find the one odd rarely used gesture that will save you 20 sec, especially since it probably took you 20 minutes to find what that gesture was. I have a few gestures for the iOS development team, if they are interested I can send them a video.
And BTW, try selecting text or an insertion point while editing a post in this forum. The screen will move around as the keyboard pops up, and it often obscures your point of insertion so you have to scroll the screen down to see what you were doing, then you might lose the insertion point by scrolling because old hands don't work like Millennial hands.
Apple needs to address these things.
