This is missing the most annoying one for me: when I type a search term into safari and it randomly interprets it as an address that it can’t resolve. E.g. “how to bake cookies” gets resolved to how%20to%20bake%20cookies (which safari tries to resolve via DNS or whatever instead of piping it to the search provider). Even better, it’s entirely nondeterministic, though it does seem to be due to some race condition with whatever determines whether it’s a search or a url, and is more likely to happen when typing quickly.

I’d say it happens about 10% of the time I type anything in the search bar. It’s incredibly annoying. Without getting into too much detail, but I confirmed they’re tracking it internally too for close to a decade and are intentionally choosing not to prioritize.

When you had gone to a site using a deep link, Safari insists on autocompleting any URL in the domain to that link you used even if you just want to go to the top-level URL/index of that site. You have to type out the entire URL and add a space at the end or something (and that still doesn't work sometimes) to stop iOS from doing that, which defeats the entire purpose of autocompletion. Btw switched off any autocorrection feature a long time ago. Still, I happen to mistype a lot compared to my old non-Apple phones (there was even an "it's not just you" article last year about it).

Apple needs to spend an entire release cycle to unfuck text entry and completion. However, with their qa lately (or lack thereof) they'd only manage to make it worse. The sad thing is they're still better than the alternatives, all things considered.

I personally reported that around time when Mac OS X 10.9 (first non-cat) came out and immediately saw it marked as duplicate. So at least 13 years and counting.

Yep, this seems to be the case whenever one types a bit too fast.

Maybe you have an ISP that captures DNS checks to return ad sites, and Safari interprets that as a real website?

But honestly it seems extremely weird that Safari would interpret something with spaces as a URL instead of a search
