Hi folks, I have an issue with using a heterogeneous array of objects conforming to a protocol - I want to write an extension on Array (or CollectionType) that applies only when Element : MyProtocol, but I can’t call methods in that extension from an instance of [MyProtocol] because "Using ‘MyProtocol' as a concrete type conforming to protocol ‘MyProtocol' is not supported”
(For more background, my full use case can be seen in this gist: https://gist.github.com/sadlerjw/2cc16b4375b02fe7f400) I’ve asked about this on swift-users (https://lists.swift.org/pipermail/swift-users/Week-of-Mon-20160321/001560.html) and got some good workarounds but no one was able to provide me with information on any future plans in swift to address this issue - whether that’s making protocols conform to themselves, or some other improved approach to heterogeneous collections. I wonder if anyone here can shed some light on this? (I’m new to the mailing lists, sorry!)
