Anyway I am trying out NextCloud and its Calendar. However their does not seem to be just an app for the Calendar. How do I add the Calendar to my iphone?


Have you thought about reading the Nextcloud user guide.

Also I’d like to point out, I’m not sure what has caused this, but in my cause, for the “password” when putting all this info into your IOS device to sync and such, I had to put an app password, not my log in pass for NextCloud, which is the info all over the internet. Not sure if it’s because of an update recently, but I think it has to do with two-factor authentication. Which I have enabled.

Settings>Personal>Security>Devices & Sessions

Found it ironically by mistake from this post. NextCloud Forum

In order to connect NextCloud calendar or contacts on iOS you need first to generate an app password as follows:
Settings → Personal → Security → “Create new app password” → Copy the credentials and use them within the iOS.
This needs to be appended to the Nextcloud official procedure here: Synchronizing with iOS — Nextcloud latest User Manual latest documentation
