So some languages that have ?. short circuit when the value is null (C#), which makes variable assignment awkward (as well as some other things). If you do variable assignment then you want ?. to return null so afterwards, which is why Kotlin handles it the way it does. I wasn’t sure which way Swift handled it which is why I asked.
