My app uses JWT for backend authentication. The server puts the refresh token in the header as a set-cookies.
On the web and Android, cookies in the header work normally on the next request.
However, in iOS, cookies do not work properly.
I want to know why the cookie is not working only in ios WebView.
If you know how to solve it, help me
The default domain/origin where the app is running on iOS in WebView is
capacitor://localhost so that could be your problem. I would recommend not relying on cookies though for auth in a Capacitor app. From my knowledge and what I’ve seen on this forum, many people have issues with them and they aren’t guaranteed to stick around between app sessions.
Here is a post I wrote a while back that describes some other options other than cookies - Best way to store Bearer token from API? - #2 by twestrick.
