Description romain.goyet 2019-04-09 16:27:51 UTC 
While there is support for on-screen software keyboard on iOS, apparently hardware keyboard support is missing.
Comment 1 Sam Lantinga 2019-06-12 03:05:55 UTC 
This is implemented now:

Actually, this is only partially fixed: some keys work, but many don't!

Here are the keys that did produce an event with type SDL_KEYDOWN:
 - Arrow keys
 - Esc key

All the other keys don't produce any event at all. Number, letters, control keys just don't do anything at all.

On iOS you need to enable text input, or the OS won't generate any keyboard events. There's nothing we can do here, that's just the way it works. Unfortunately enabling text input will also pop up the onscreen keyboard, and you can't tell until you do that whether a hardware keyboard is attached - by OS design.

That's my understanding, if you find out differently, please let me know!

You might very well be right, thanks for replying.
I'll try to look things up and will reopen this ticket if I've anything interesting to add to the conversation :)
