Is KDE connect good for iOS devices?
For my iPhone/Linux combination, I would say, yes.
I am using it for simple file transfers whenever I’m lazy to use a cable.
It’s not as perfect as with Android, though.
Ensure that iPhone does not get locked, otherwise transfers get stuck and won’t resume.
Preparation of media files takes quite some time – there seems to be some preprocessing on the iPhone before files are getting transferred. Most notable when sending videos from phone to my computer.
(Recent pairing issues on my newly updated iOS 17.4 have been solved by Settings > Advanced Settings: Erasing saved device cache and Delete host certificate.)
How were you able to click on those two options? mine has the same connection issues, yet it won’t even let me erase device cache or host certificate. Both buttons appear red for some reason.
I think they are just red to warn you.
You should be able to tap on them, then restart the app.
