I use it almost exclusively/when it makes sense to. But so many people are surprised that I use it.
Part of it is because I was an android user until about 2015 and that was always a feature on the phones I had. I also use it because I have small hands and the biggest iPhone so I find it easier to type one-handed sometimes.
I do but it’s often frustrating to due to two notable issues with Apple’s implementation:
The don’t use the conventional “swipe in a loop over a letter to use two of that letter” approach. Instead they just try to figure it out if you swipe over a letter.
They don’t take grammar into consideration when trying to determine what word you just swiped.
Both of these lead to the feature failing A LOT to under what I’m trying to say.
