I've got a UITableViewCell that is in a TableView that is in editing mode. I have the cell's editing accent set to the Detail option. How can I access that little circle detail button that appears when my table view goes into editing mode, so that I can add a target to it?

I want to be able to get an array of all the available emojis in Swift. What I mean by available is all the ones that are current accessable to the device. Like when Apple adds some new emojis, I would like to not have to change any code, and the new emojis just get added in the array with all the other ones.If getting updated emojis is not possible, then how can I get all of the current emojis into an array (or perhaps a .plist file I can then load into an array) so I can access them in code?
