I have run into the following a number of times. I have always found a workaround, but I think there is a better (more Kotlin) way to solve it. The situation is when I have a wrapper around an Array. I often have a few functions/variables/constants etc I want to associate with the array, so a wrapper seems like a good way to organize the code. However, I get a message that says I need to implement the Iterator interface and I never succeed so I give up and just expose the Array. I see the Iterator interface, but I can’t figure out how to implement it, let alone know even if I did, would I just run into another problem?
A simple example of a class that wraps a private Array object that I could loop though would be helpful.
Of course, if this is simply not a good idea in Kotlin, that would be good to know too.
