Estimote NFC iOS

I would like to implement NFC in the iOS app. Is there any documentation that explains how to write data to NFC tags.
I came across a link regarding NFC.


But the above link explains mostly about android integration. Are there any specific APIs available in iOS Estimote SDK to write NFC messages to beacon?

Interested in this as well. From what I understand, only the Android SDK supports writing to NFC tag but have been unable to get information on this can be done. Sample app templates seems to be missing/broken for “writing” as well
