Is there a reason why Apple's iPhone spellcheck is often really poor, significantly worse than both LLMs and just...human eyes?

I often find myself butchering the spelling of a word in a way where the correct answer is obvious to human eyes (probably because of "typoglycemia" [1]) and an AI LLM immediately understands what I meant to say, but Apple's spellcheck has "No Guesses Found."

Does anyone else have this experience?

Yes but it’s much broader. Just in general the lack of Steve Jobs noticing these glaring issues and coming down hard to solve them is pretty clear.

I remember when macbooks briefly came out with a ridiculously bright standby led that required Black electrical tape over if you wanted to sleep with it in the house. Shortly after no more status leds on any MacBook (thank you!).

Nowadays i find non stop little annoyances with threads from others on the same issues on Apple devices. From.the.overly.prominent.full.stop when searching textually in the url bar to the crappy spell check and crappy spam filtering. As much as Jobs apparently came across as an asshole there’s a need for someone at the top to say ‘WTF is this, fix it or get fired!’.

  • I worked at Apple and heard a lot of Steve stories. He really did personally approve everything. He would be sitting in a room, and team leads would all line up to give their quick 2-minute update. So it's the MacBook Air guy's turn. He comes in and places his prototype down in front of Steve. Steve opens the lid. Two seconds later he picks up the laptop and heaves it so hard it skipped across the table like a stone on water: "I said fxxking INSTANT ON!!" The poor guy collected his prototype and exited the room. Later the MacBook Air launched... it fxxking turned on the moment you open the lid

    • Good product development really does seem to require some sort of leader who demands quality and smacks people when they don't deliver. Linux is nice because of Torvalds for example.

    • Latency is actually an interesting case, because it’s one of those things that, by default, nobody owns end-to-end

      If you’re booting a computer or building web search, every subsystem can contribute to latency. If you have more teams and more features, you’re likely to have more latency.

      In the early days of Google, Larry Page would push hard on this as well, in person. So Google search was fast.

      But later the company became larger and bureaucratized, so nobody was in charge of latency. So then each team contributes a bit to latency, and that’s what ends up shipping.

      Google products used to be known for being fast, but they’ve reverted to the mean

    • The instant on thing actually bothered me enough to make switch from windows back to Mac( by proxy the idle battery drain on windows was also pretty terrible)

    • >Two seconds later he picks up the laptop and heaves it so hard it skipped across the table like a stone on water: "I said fxxking INSTANT ON!!"

      When did the OG MacBook Air have instant on at launch in 2008?

      IIRC the M1 brough Instant on and Jobs wasn't around anymore.

  • I've also found a lot of this stuff is due to naysayers telling people that things can't be fixed (because really they don't want to bother). You need a strong leader to say "no it can and we will".

    • It takes a village. Also to be successful in tech it takes an asshole. No way around it. At some point all successful companies share an overly aggressive visionary. The entire company doesn’t need to be toxic, but the apex does. If you don’t like it, don’t climb the ladder.

    • Not just that, but the strong leader needs to ensure that it can be fixed.

      Yelling at a rank-and-file to unfuck some random system, then not giving them any time, resources, or tools to fix it is just being a dictatorial dickhead.

  • > From.the.overly.prominent.full.stop when searching textually in the url bar

    One of the most aggravating things in iOS. Trips me up almost every day (and it's been there for what? 10 years now?)

    • Wait until you realize that the icon of the period and spacebar don't at all line up to the touch area due to touch gravitation. You can tap slightly more on the spacebar side and still end up with a period. https://www.reddit.com/r/iphone/comments/1ekszul/comment/lgn...

      So if you suffer from this it's not even your fault. You're literally hitting the spacebar but some incentive at Apple in their org structure has led to the period literally having waaaay too much weighting and the lack of exec oversight at Apple in the post Jobs days is leading to us all.typing.periods.whenever.we.just.wanted.to.search.

  • It's hard to pinpoint exactly what it is, but yes, there seems to be an increasing number of small issue with Apple devices. They aren't major stuff simply not work, but yes, spam filter being pretty terrible, text overlapping on non flagship phones (e.g. the iPhone SE). All sorts of minor annoyances.

    • Yep I've worked at other big tech where they had periodic "executive bug filing" where executives would flag minor things that are annoying. These minor issues would then have higher than normal priority purely by virtue of being flagged by an exec. I have a likely controversial opinion that this executive bug filing actually led to better outcomes.

      It did break prioritization in the opinion of the ground level teams and their goals but I argue it's not bad to at least periodically do this since grating against the current org structure prioritization and goals is not a bad thing to do on occasion.

      Chances are they'll find there's no team that considers themselves the owners of spell check or spam filtering and the goals the keyboard team are going for is likely some silly thing like "number of sentences with correct punctuation" leading to the current ridiculous outcomes where the period in the URL is way too prominent, especially considering we don't even type full URLS into the search bar that often these days.

      Dear Apple leads: if you're reading this do a short initiative where execs aim to file an annoyance a day. It's not hard to find such. There will be some complaints at the ground level that these executive annoyances get too much priority but part of that will be because you're questioning lower level org priorities (a healthy thing to do!), not because the issues don't matter. The end result will bring Apple a bit more in line with the quality we saw during the Jobs period since this is exactly the kind of shake up he did on occasion.

  • Currrent MBPs have bright green/orange charging lights on both sides of the magsafe connector. They're bright enough I have to block them when I'm in a hotel and my laptop is in the same room.

  • There has to be something going on with iOS Safari and the keyboard because my typing goes to complete shit in ways it never does in any other application.

    Here are some random examples I thought of for this comment. Notice how everything is spelled wrong as though the screen input doesn’t match the location of the buttons.

    - tomoroww eather in united.kingdom

    - lookip exhange rate

    - devopper news

    - download twotter.video

    • I notice this as well, i think it is because the autocorrect is turned off and we may just be so used to it learning our typing habits that our "raw" typing is really that bad

  • > I remember when macbooks briefly came out with a ridiculously bright standby led that required Black electrical tape over if you wanted to sleep with it in the house. Shortly after no more status leds on any MacBook (thank you!).

    The lack of status LEDs is actually the only thing I really REALLY hate about MacBooks!

    Too often I have been bitten by the thing not properly going to sleep because SOMETHING keeps a wake lock (and of course macOS doesn't indicate this anywhere outside of Energy Monitor, nested in System Activity) and overheating in my bag as a result. A simple LED would have been a good visual indicator that it is still awake.

There's nothing more frustrating than when you type the word you want to type, it changes it to a different word, you delete it and type the word you wanted to type again and then rinse/repeat 3 to 4 times before you have the word you actually wanted.

And if you're not paying attention, your message ends up looking like you're having a stroke.

  • It used to be that if you typed, deleted the correction, and retyped, that spelling would now be the preferred and you wouldn’t have to play that game anymore. Apple broke that years ago.

I'd be happier if the suggested word didn't move between the time I saw it appear and the time my finger touched the screen.

I have the same experience. Some things I’ve noticed:

- they really don’t want you saying bad words of any kind.

- they do not look at context at all

- they focus too much on the first letter of the word for suggestions

  • > they focus too much on the first letter of the word

    They also do that in Apple Notes. On the iPad the search can only match word prefixes. So if you type "oo" and the entire note consists of just the word "foo", it will find nothing. This doesn't even require fuzzy search, yet they couldn't be bothered while solving the much more difficult handwriting recognition problem.

    Also the iPhone's Settings app still doesn't have all settings in the search index. So it's impossible to find the section "headphone safety" & "reduce loud audio" using words like "headphone", "audio" or "safety". This setting was introduced five years ago, by the way.

  • > they really don’t want you saying bad words of any kind.

    Not true anymore, I just typed fuck in this comment without having to fight it. They made a change I think last year and they even announced it.

    > they do not look at context at all

    Also not true. It's true that they're not perfect at it, but replacement after you typed 2 more words happen specifically because it can tell better what you want to say. Sometimes works against you because language is highly personal.

Meanwhile, vim's spell checker is one of the best I have used. I recommend reading [:h spell](https://vimhelp.org/spell.txt.html#spell).

Here are some nice examples (excluding obvious edit distance based ones which it does right)

"snowbalfight" --> "snowball fight"

"unrelevant" --> "irrelevant"

"fone" --> "phone"

"the the" --> "The"

And all of this with auto capitalization if it notices you're at the start of a sentence, and stuff like handling proper nouns, punctuations, etc,.

What I find really interesting is swipe-type spell checking (its basically word prediction) on phones. That is a really cool problem to solve well. Sometimes it works like a dream and other times it's annoying. I wonder how they write those.

> Is there a reason why Apple's iPhone spellcheck is often really poor, significantly worse than both LLMs and just...human eyes?

It's somewhat funny that human performance is seen as a baseline here, and not the pinnacle of achievement to aim for.

(I agree with you. I just find it entertaining.)

Bit off-topic - macOS has excellent built-in dictionary. Just select the word in any app, press Ctrl+Command+D and it opens it. It even guesses most incorrect words correctly. Also translation available if it exist for current keyboard locales.

E.g.

> No entries for "typoglycemia", did you mean "hypoglycemia"?

  • These user activated dictionaries tend to be excellent (even in vim, a pretty barebones system, I tend to get fantastic guesses from the machine).

    Actually, come to think of it, the problem must be a bit easier than on smartphones, right? Real keyboard input is very precise. Smartphone keyboards already guess what word you were trying to spell, so they are influencing the typos in the direction of likely words… cannibalizing the very guess list that the dictionary uses!

  • Alfred ties into it nicely too, you can type `spell someword` and the completions below have the various spellings of words, fuzzy matched. Select one and the word goes onto your clipboard

  • that's great. I usually use the context menu on MacOS and the "Define" option on long press on iOS

    That said, trying to use long press on iOS (or whatever it actually is), is one of those places that often drives me nuts. I don't know if the issue is a specific app or the OS or what but sometimes I want the popup menu to appear and I can't get it to appear. Or I do something to make it appear but it doesn't appear for x hundred milliseconds, during which I think it didn't get my gesture so I start a new one, just as it's finally responding in which case my new gesture dismisses it. Repeat 3-4 times before I'm ready to tear my hair out

    It also shows why canvas based websites suck. Open Google Docs, select a word, press Cmd-Ctrl-D, ... nothing. Try it in gmail (which is not canvas based) and it works.

> Is there a reason why ...

Yes: Apple doesn't care.

> Does anyone else...

Yes. I just typed in "Tipografical earer" - and iOS 18.6 suggested "Tipograxical" for the first word, and one of "eared", "eager", and "eater" for the second word.

The spell check is truly bad. It boggles the mind how this is even possible given how solved the problem is everywhere else. Also the period being to the right of the spacebar such that it gets hit instead of space. So annoying!

I run into this all the time. I've just given up on the built-in spell checker and search the word in Google now.

I feel the same way about Android's. It just seems like spell check used to be so much better then years ago. But I'm not sure whether it's comparing mobile with desktop expectations. It really seems extremely dumb on Android.

  • When I used Windows Phone 8.1 I felt like I was typing text twice as fast as on Android. Better suggestions, more accurate keyboard inputs on the same screen size, and selecting an entire word was just a single tap which made fixing a typo very quick as well. Meanwhile back then it was impossible to make certain text selections without a bluetooth keyboard because of how Android constantly tried "fixing" touch-based selections. It's sad that Microsoft shut down the only system & UI that felt like the developers were actually thinking of the user when designing it. To this day no other mobile OS is as friendly to left-handed users.

Wouldn't typoglycemia be lack of typos in your blood? Don't you mean the opposite?

  • "Hypo", meaning low; "glyc-", meaning sugar; and "emia", meaning of the blood. "Low sugar of the blood". (With apologies to chubbyemu.)

    Since "typo" comes from "typography", it roughly means "symbolic". So "typoglycemia" should mean "symbolic sugar of the blood". Low typos in your blood would be "hypotypemia".

    I have no idea why "typoglycemia" refers to a human ability to autocorrect, but it brings me joy, so I'm not going to question it ^_^

I mean, TBH I would expect this to be true: an LLM is trained over a massive corpus of internet data, which contains many typos, and is required to accurately predict tokens despite edit errors. A spellchecker is typically running a deterministic algorithm really, really quickly, and has hardcoded limits on acceptable edit distance (and has no learned knowledge of what looks correct/incorrect to human eyes). An LLM should generally trounce a spellchecker at figuring out what you meant to type, unless the spellchecker is secretly a tiny LLM / ML model of some kind under the hood.

I have definitely noticed this too. I also use the built in swipe to type feature, and it may as well be a coin flip as to whether it gets the word right. I get that swiping is vague, but even a little bit of frequency prediction would tell you that “sounds good” is going to be more likely than “sings hood”. It’s an absolutely infuriating feature.

  • This drives me insane.

    I use the swipe feature because I guess I have wide fingertips and frequently hit unintended, adjacent keys when pecking on the keyboard (especially as I’ve gotten older). The words produced by swiping often make no grammatical sense, and are frequently esoteric words that I just can’t believe rank high enough on a basic frequency list to suggest. Not to mention my own vocabulary, which apparently is not considered by the keyboard at all.

    I had a way better experience using SwiftKey on my android phone 15 years ago.
