I remember being amazed by how great swiping was, and after using it recently (it's not really great on gboard or samsung keyboard either, not bad but just meh) I was wondering if it was just rose tinted glass. But nope, I booted up my old nexus 5 with a normal gboard (not even swiftkey!) and it was still amazing. The contrast was amazing even when I wiped typing data on both phones to make sure that it was a fair comparison.
I guess the most glaring difference was the subtle, but extremely important handling of edge cases or particularly ambigious letter combinations. Even the "bad" modern google keyboard is still 95% accurate, but the difference between that and the 99% accuracy on my nexus 5 basically makes all the difference. It goes from predictive magic to having to swipe across every single letter to make sure it works.
I remember not even knowing the spelling of words but being able to swipe in the general direction of letters I thought might be correct and it inputting the correct word.
Now now it seems I have to have near perfect tracing and pathing to get correct words.
It's very disappointing.
Note: the above paragraph was typed with swipe typing. I actually typed “Y O U” for both of the above instances of “your.”
Apple swipe typing is the opposite of AI: it’s like an idiot is going behind you taking even correct words you swipe and turning them into gibberish. Don’t even get me started about its obsession with “it’s” and “we’re” to the exclusion of the words without apostrophes. Ughhhhhh
//Edit: Would really like to know for what I got down voted for?
Therefore, I have the impression that this is not a feature Apple would endorse much.
It's just less secure to use them than the one built into the OS because the third party keyboards might run input through some web service instead of keeping it completely local.
i would not for the life of me trust google with a 1st attempt at any hardware implementation. especially with one that will be pretty expensive
