How do I have to configure my iPhone device for CardDAV synchronizing?
Please use the following iPhone CardDav description as starting point. This documentation should help you figuring out how to configure your device.
In Settings open «Accounts & Passwords»
Select «Add Account»
Select «Add CardDAV Account»
Insert server name (e.g. rc.syncgw.com/sync.php), your user name (e.g. firstname.lastname@example.org), your password and a description. Then click on «Next». Please note, it might happen your iPhone claims the server certificate does not match. This might happen if you use Let's Encrypt certificates. In this case, please accept certificate shown.
