Arcade code to create unique ID for new field

[anonymous55]

Hello

I need to create new field with unique ID for hosted layer which already published in AGOL. I can't find any Arcade code for creating unique ID for new field in AGOl here. I am thinking about to copy object id to new field but I don't know the arcade code for it.

I will appreciate any help

Hi anonymous55, 

You might find the Guid function in Arcade useful for this to create unique guids for each feature with Field Calculation.
