Well, it seems that we will have to wait for the reflection mechanism to be in place.

I started off a thread about this a while back: https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20151207/001455.html

Based on the feedback I got, it seemed like the design for a serious custom annotation system should wait until work starts on a macro system so that they can be designed to complement each other. IMO, neither the java nor python versions feel right for swift and we can do a lot better than just copying them so it’s worth spending the time to get it right.

Additionally, the property behaviors proposal currently on the table would cover some of the use cases for annotations, depending on where it lands. It seems plausible that we can make all these features work together in a nice way.

Maybe it’s worth setting up a wiki page or something for use cases of annotations to help inform a future design as well as the design of related features?

Dear all,

I am quite new to Swift, though I have made some small checks within Xcode, so I could have missed some feature in swift that provides a functionality similar to the want I am proposing.

I have been using my own annotations in Java or decorators in Python, and I would like to have an equivalent functionality in Swift. As far as I have seen, there are attributes that can provide a similar solution, but AFAIK you cannot create new ones. Would it be possible to add this feature in Swift.

       Thanks in advance,

               Jose M.
